Oracle Enterprise Manager: Integration with 3rd Party Systems
 
18:26
Enterprise Manager has a number of management connectors to integrate with popular 3rd party management systems. The management connectors leverage EM’s connector framework in order to forward event and incident details to 3rd party systems. Besides the management connectors, Enterprise Manager also has a number of Advanced Notification Methods when the use case is more complicated or when there is no management connector available. Enterprise Manager is highly extensible and provides a Connector Framework API which leverages web service calls to create and update events or tickets in 3rd party systems. We provide a Connectors Integration Guide with instructions and examples to build your own connector. See Enterprise manager online documentation for more information: http://docs.oracle.com/cd/E73210_01/nav/connectors.htm http://docs.oracle.com/cd/E73210_01/EMADM/GUID-B48F6A84-EE89-498D-94E0-5DE1E7A0CFBC.htm#EMADM9066 http://docs.oracle.com/cd/E73210_01/EMCIG/GUID-FBA700A1-B2F0-4A7B-980C-E4816A21FAD4.htm#EMCIG169 Copyright © 2017 Oracle and/or its affiliates.

This means a given student can be enrolled into many courses and a given course can have many students enrolled. Below is the question asked in an interview for SQL Server Developer role. Write a SQL script to insert data into StudentCourses table. Here are the rules that your script should follow. 1. There will be 2 inputs for the script Student Name - The name of the student who wants to enroll into a course Course Name - The name of the course the student wants to enroll into 2. If the student is already in the Students table, then use that existing Student Id. If the student is not already in the Students table, then a row for that student must be inserted into the Students table, and use that new student id. 3. Along the same lines, if the course is already in the Courses table, then use that existing Course Id. If the course is not already in the Courses table, then a row for that course must be inserted into the Courses table, and use that new course id. 4. There should be no duplicate student course enrollments, i.e a given student must not be enrolled in the same course twice. For example, Tom must not be enrolled in C# course twice. Answer : To avoid duplicate student course enrollments create a composite primary key on StudentId and CourseId columns in StudentCourses table. With this composite primary key in place, if someone tries to enroll the same student in the same course again we get violation of primary key constraint error. Alter table StudentCourses Add Constraint PK_StudentCourses Primary Key Clustered (CourseId, StudentId) Here is the SQL script that inserts data into the 3 tables as expected Declare @StudentName nvarchar(50) = 'Sam' Declare @CourseName nvarchar(50) = 'SQL Server' Declare @StudentId int Declare @CourseId int -- If the student already exists, use the existing student ID Select @StudentId = Id from Students where StudentName = @StudentName -- If the course already exists, use the existing course ID Select @CourseId = Id from Courses where CourseName = @CourseName -- If the student does not exist in the Students table If (@StudentId is null) Begin -- Insert the student Insert into Students values(@StudentName) -- Get the Id of the student Select @StudentId = SCOPE_IDENTITY() End -- If the course does not exist in the Courses table If (@CourseId is null) Begin -- Insert the course Insert into Courses values(@CourseName) -- Get the Id of the course Select @CourseId = SCOPE_IDENTITY() End -- Insert StudentId & CourseId in StudentCourses table Insert into StudentCourses values(@StudentId, @CourseId) If required, we can very easily convert this into a stored procedure as shown below. Create procedure spInsertIntoStudentCourses @StudentName nvarchar(50), @CourseName nvarchar(50) as Begin Declare @StudentId int Declare @CourseId int Select @StudentId = Id from Students where StudentName = @StudentName Select @CourseId = Id from Courses where CourseName = @CourseName If (@StudentId is null) Begin Insert into Students values(@StudentName) Select @StudentId = SCOPE_IDENTITY() End If (@CourseId is null) Begin Insert into Courses values(@CourseName) Select @CourseId = SCOPE_IDENTITY() End Insert into StudentCourses values(@StudentId, @CourseId) End Use the following statement to execute the stored procedure Execute spInsertIntoStudentCourses 'Tom','C#'

Oracle Enterprise Manager: Advanced Threshold Management
 
16:34
Advanced Thresholds allow you to define and manage alert thresholds that are either adaptive (self-adjusting) or time-based (static). There are monitoring situations in which different workloads for a target occur at regular (expected) intervals. Under these conditions, a static alert threshold would prove to be inaccurate. For example, the accurate alert thresholds for a database performing Online Transaction Process (OLTP) during the day and batch processing at night would be different. Similarly, database workloads can change based purely on different time periods, such as weekday versus weekend. In both these situations, fixed, static values for thresholds might result in false alert reporting. See Enterprise manager online documentation for more information: http://docs.oracle.com/cd/E73210_01/EMADM/GUID-02356AB5-4B03-46AE-8354-2E9517A8F439.htm#EMADM15123 ================================= To improve the video quality, click the gear icon and set the Quality to 1080p/720p HD.

UniqueIdentifier, Guid, Newid, NewSequentialid in SQL Server
 
09:27
Click here to Subscribe to IT PORT Channel : https://www.youtube.com/channel/UCMjmoppveJ3mwspLKXYbVlg Uniqueidentifiers are also referred to as GUIDs. (Globally Unique IDentifier). That is, the API call that returns a GUID is guaranteed to always return a unique value across space and time. Its related to MAC address based On network card and the system time. The uniqueidentifier data type in SQL Server is stored natively as a 16-byte binary value. We can get a Guid from NewID() or NewSequentialID() NEWID() - randomly generates a guaranteed unique value based on the identification number of the server's network card plus a unique number from the CPU clock. We can use this in Insert, Select Statement. NEWSEQUENTIALID() - generates these values in sequential order as opposed to randomly. We can use this in Create Statement default value and We can’t use in Insert, Select Statement The major advantage of using GUIDs is that they are unique across all space and time. This comes in handy if you're consolidating records from multiple SQL Servers into one table, as in a data warehousing situation. GUIDs are also used heavily by SQL Server replication to keep track of rows when they're spread out among multiple SQL Servers The main disadvantage to using GUIDs as key values is that they are BIG. At 16 bytes a pop, they are one of the largest datatypes in SQL Server. Indexes built on GUIDs are going to be larger and slower than indexes built on IDENTITY columns, which are usually ints (4 bytes)

create sequence in sql server In this video we will discuss sequence object in SQL Server. Sequence object Introduced in SQL Server 2012 Generates sequence of numeric values in an ascending or descending order Text version of the video http://csharp-video-tutorials.blogspot.com/2015/10/sequence-object-in-sql-server-2012.html Slides http://csharp-video-tutorials.blogspot.com/2015/10/sequence-object-in-sql-server-2012_26.html All SQL Server Text Articles http://csharp-video-tutorials.blogspot.com/p/free-sql-server-video-tutorials-for.html All SQL Server Slides http://csharp-video-tutorials.blogspot.com/p/sql-server.html All Dot Net and SQL Server Tutorials in English https://www.youtube.com/user/kudvenkat/playlists?view=1&sort=dd All Dot Net and SQL Server Tutorials in Arabic https://www.youtube.com/c/KudvenkatArabic/playlists Creating the Incrementing Sequence : The following code create a Sequence object that starts with 1 and increments by 1 CREATE SEQUENCE [dbo].[SequenceObject] AS INT START WITH 1 INCREMENT BY 1 Generating the Next Sequence Value : Now we have a sequence object created. To generate the sequence value use NEXT VALUE FOR clause SELECT NEXT VALUE FOR [dbo].[SequenceObject] Output : 1 Every time you execute the above query the sequence value will be incremented by 1. I executed the above query 5 times, so the current sequence value is 5. Retrieving the current sequence value : If you want to see what the current Sequence value before generating the next, use sys.sequences SELECT * FROM sys.sequences WHERE name = 'SequenceObject' Alter the Sequence object to reset the sequence value : ALTER SEQUENCE [SequenceObject] RESTART WITH 1 Select the next sequence value to make sure the value starts from 1 SELECT NEXT VALUE FOR [dbo].[SequenceObject] Using sequence value in an INSERT query : CREATE TABLE Employees ( Id INT PRIMARY KEY, Name NVARCHAR(50), Gender NVARCHAR(10) ) -- Generate and insert Sequence values INSERT INTO Employees VALUES (NEXT VALUE for [dbo].[SequenceObject], 'Ben', 'Male') INSERT INTO Employees VALUES (NEXT VALUE for [dbo].[SequenceObject], 'Sara', 'Female') -- Select the data from the table SELECT * FROM Employees Creating the decrementing Sequence : The following code create a Sequence object that starts with 100 and decrements by 1 CREATE SEQUENCE [dbo].[SequenceObject] AS INT START WITH 100 INCREMENT BY -1 Specifying MIN and MAX values for the sequence : Use the MINVALUE and MAXVALUE arguments to specify the MIN and MAX values respectively. Step 1 : Create the Sequence object CREATE SEQUENCE [dbo].[SequenceObject] START WITH 100 INCREMENT BY 10 MINVALUE 100 MAXVALUE 150 Step 2 : Retrieve the next sequence value. The sequence value starts at 100. Every time we call NEXT VALUE, the value will be incremented by 10. SELECT NEXT VALUE FOR [dbo].[SequenceObject] If you call NEXT VALUE, when the value reaches 150 (MAXVALUE), you will get the following error The sequence object 'SequenceObject' has reached its minimum or maximum value. Restart the sequence object to allow new values to be generated. Recycling Sequence values : When the sequence object has reached it's maximum value, and if you want to restart from the minimum value, set CYCLE option ALTER SEQUENCE [dbo].[SequenceObject] INCREMENT BY 10 MINVALUE 100 MAXVALUE 150 CYCLE At this point, whe the sequence object has reached it's maximum value, and if you ask for the NEXT VALUE, sequence object starts from the minimum value again which in this case is 100. To improve performance, the Sequence object values can be cached using the CACHE option. When the values are cached they are read from the memory instead of from the disk, which improves the performance. When the cache option is specified you can also specify the size of th cache , that is the number of values to cache. The following example, creates the sequence object with 10 values cached. When the 11th value is requested, the next 10 values will be cached again. CREATE SEQUENCE [dbo].[SequenceObject] START WITH 1 INCREMENT BY 1 CACHE 10 Using SQL Server Graphical User Interface (GUI) to create the sequence object : 1. Expand the database folder 2. Expand Programmability folder 3. Right click on Sequences folder 4. Select New Sequence Next video : Difference between SEQUENCE and IDENTITY in SQL Server

These are already discussed in SQL Server Tutorial. 1. Self-Join - http://www.youtube.com/watch?v=qnYSN_7qwgg 2. CTE - http://www.youtube.com/watch?v=ZXB5b-7HJHk 3. Recursive CTE - http://www.youtube.com/watch?v=GGoV0wTMCg0 Here is the problem definition: 1. Employees table contains the following columns a) EmployeeId, b) EmployeeName c) ManagerId 2. If an EmployeeId is passed, the query should list down the entire organization hierarchy i.e who is the manager of the EmployeeId passed and who is managers manager and so on till full hierarchy is listed. For example, Scenario 1: If we pass David's EmployeeId to the query, then it should display the organization hierarchy starting from David. Scenario 2: If we pass Lara's EmployeeId to the query, then it should display the organization hierarchy starting from Lara. We will be Employees table for this demo. SQL to create and populate Employees table with test data Create table Employees ( EmployeeID int primary key identity, EmployeeName nvarchar(50), ManagerID int foreign key references Employees(EmployeeID) ) GO Insert into Employees values ('John', NULL) Insert into Employees values ('Mark', NULL) Insert into Employees values ('Steve', NULL) Insert into Employees values ('Tom', NULL) Insert into Employees values ('Lara', NULL) Insert into Employees values ('Simon', NULL) Insert into Employees values ('David', NULL) Insert into Employees values ('Ben', NULL) Insert into Employees values ('Stacy', NULL) Insert into Employees values ('Sam', NULL) GO Update Employees Set ManagerID = 8 Where EmployeeName IN ('Mark', 'Steve', 'Lara') Update Employees Set ManagerID = 2 Where EmployeeName IN ('Stacy', 'Simon') Update Employees Set ManagerID = 3 Where EmployeeName IN ('Tom') Update Employees Set ManagerID = 5 Where EmployeeName IN ('John', 'Sam') Update Employees Set ManagerID = 4 Where EmployeeName IN ('David') GO Here is the SQL that does the job Declare @ID int ; Set @ID = 7; WITH EmployeeCTE AS ( Select EmployeeId, EmployeeName, ManagerID From Employees Where EmployeeId = @ID UNION ALL Select Employees.EmployeeId , Employees.EmployeeName, Employees.ManagerID From Employees JOIN EmployeeCTE ON Employees.EmployeeId = EmployeeCTE.ManagerID ) Select E1.EmployeeName, ISNULL(E2.EmployeeName, 'No Boss') as ManagerName From EmployeeCTE E1 LEFT Join EmployeeCTE E2 ON E1.ManagerID = E2.EmployeeId

Omnichannel Services - Use UUID Keys to Your Data
 
03:46
Today I'm going to talk to you about why it's important to use universally unique identifiers (UUID) as keys to your data, and I will show you some of the problems that they can solve. In the distributed computing world of mobile devices and an internet of things it becomes almost impossible to have one source for key generation, so each device need to be able to create their own keys, while still making sure that those keys are unique. The answer is to use UUIDs, which is a standard by the Open Software Foundation, and there's an industry wide support for them (http://en.wikipedia.org/wiki/Universally_unique_identifier). For example, PHP, Java, .NET, Oracle, and MySQL all have ways to generate them, and SQL Server and ProgresSQL even has native UUID data types. Let talk about the benefits of using UUIDs, and I will start by pointing out some of the problems they can solve. When doing our data models, we have been taught to normalize our databases so that we find primary keys as one of the columns or a combination of columns. If not found, we usually add a generated id, such as an automatically incremented integer. One problem with using a multi-column key is that the queries become more complex as each column needs to be included in each join, and more complex means a lower performance and also larger indices. Another problem is that it's harder for the consumer of the data to know which columns are included in the key. With auto-generated keys, we get a simpler join, but a problem is that each consumer need to ask the generator for a valid key, and another problem is that there will be "holes" in the sequence when rows are deleted. Yet another problem is that any data type used has a fixed limit (even if huge), so it will eventually run out. Also, it becomes tricky for a client to find out which id was generated during an insert. With UUIDs, we get the same benefit of the simpler join as we got with the auto-generated keys, but now each user of the data can generate new keys and rows, without access to any central key generator -- it can even happen while disconnected. So any device or thing can generate a key and the maximum 3.4 x 10^38 combinations both ensure that each key is unique and that there's no practical limit of keys. But even UUIDs have drawbacks, and the most obvious is that they are hard to remember. Therefore, it's a good practice to provide ways of accessing data using attributes that are easier to remember. For example, provide a service that can get an order by providing an order number in addition to getting it using the primary key, the UUID. So make sure that you use UUIDs as keys to your data to allow distributed key generation, simplified joins, and get better performance.

Prevent sql injection with dynamic sql

In Part 140, we have implemented "Search Page" using dynamic SQL. Since we have used parameters to build our dynamic SQL statements, it is not prone to SQL Injection attack. This is an example of good dynamic SQL implementation. I have seen lot of software developers, not just the beginners but even experienced developers, buidling their dynamic sql queries by concatenating strings instead of using parameters without realizing that they are opening the doors for SQL Injection. Please check my blog at the following link for code used in the demo. http://csharp-video-tutorials.blogspot.com/2017/04/prevent-sql-injection-with-dynamic-sql.html Since we are concatenating the user input values to build the dynamic sql statement, the end user can very easily inject sql. Imagine, what happens for example, if the user enters the following in the "Firstname" textbox. ' Drop database SalesDB -- With the above SQL injected into the "Firstname" textbox, if you click the "Search" button, the following is the query which is sent to SQL server. This will drop the SalesDB. Select * from Employees where 1 = 1 AND FirstName = '' Drop database SalesDB --' On the other hand, if you use parameters to build your dynamic SQL statements, SQL Injection is not an issue. The following input in the "Firstname" textbox, would not drop the SalesDB database. ' Drop database SalesDB -- The text the user has provided in the "Firstname" textbox is treated as the value for @Firstname parameter. The following is the query that is generated and executed. exec sp_executesql N'Select * from Employees where 1 = 1 AND [email protected]',N'@FirstName nvarchar(26)',@FirstName=N''' Drop database SalesDB --' We don't have this problem of sql injection if we are using stored procedures. "SearchPageWithoutDynamicSQL.aspx" is using the stored procedure "spSearchEmployees" instead of dynamic SQL. The same input in the "Firstname" texbox on this page, would generate the following. Notice, whatever text we typed in the "Firstname" textbox is treated as the value for @FirstName parameter. exec spSearchEmployees @FirstName=N''' Drop database SalesDB --' An important point to keep in mind here is that if you have dynamic SQL in your stored procedure, and you are concatenating strings in that stored procedure to build your dynamic sql statements instead of using parameters, it is still prone to SQL injection. If this is not clear at the moment don't worry, we will discuss an example of this in out next video. So in summary, while dynamic sql provides great flexibility when implementing complicated logic with lot of permutations and combinations, if not properly implemented it may open doors for sql injection. Always use parameters to build dynamic sql statements, instead of concatenating user input values. Another benefit of using parameters to build dynamic sql statements is that it allows cached query plans to be reused, which greatly increases the performance. We will discuss an example of this in our upcoming videos.

Dynamic SQL in Stored Procedure
 
09:32
In this video we will discuss, using dynamic sql in a stored procedure and it's implications from sql injection perspective. We will discuss performance implications of using dynamic sql in a stored procedure in a later video. Text version of the video http://csharp-video-tutorials.blogspot.com/2017/04/dynamic-sql-in-stored-procedure.html Slides http://csharp-video-tutorials.blogspot.com/2017/04/dynamic-sql-in-stored-procedure_11.html All SQL Server Text Articles http://csharp-video-tutorials.blogspot.com/p/free-sql-server-video-tutorials-for.html All SQL Server Slides http://csharp-video-tutorials.blogspot.com/p/sql-server.html All SQL Server Tutorial Videos https://www.youtube.com/playlist?list=PL08903FB7ACA1C2FB All Dot Net and SQL Server Tutorials in English https://www.youtube.com/user/kudvenkat/playlists?view=1&sort=dd All Dot Net and SQL Server Tutorials in Arabic https://www.youtube.com/c/KudvenkatArabic/playlists Consider the following stored procedure "spSearchEmployees". We implemented this procedure in Part 139 of SQL Server tutorial. This stored procedure does not have any dynamic sql in it. It is all static sql and is immune to sql injection. Create Procedure spSearchEmployees @FirstName nvarchar(100) = NULL, @LastName nvarchar(100) = NULL, @Gender nvarchar(50) = NULL, @Salary int = NULL As Begin Select * from Employees where (FirstName = @FirstName OR @FirstName IS NULL) AND (LastName = @LastName OR @LastName IS NULL) AND (Gender = @Gender OR @Gender IS NULL) AND (Salary = @Salary OR @Salary IS NULL) End Go Whether you are creating your dynamic sql queries in a client application like ASP.NET web application or in a stored procedure, you should never ever concatenate user input values. Instead you should be using parameters. Notice in the following example, we are creating dynamic sql queries by concatenating parameter values, instead of using parameterized queries. This stored procedure is prone to SQL injection. Let's prove this by creating a "Search Page" that calls this procedure. Create Procedure spSearchEmployeesBadDynamicSQL @FirstName nvarchar(100) = NULL, @LastName nvarchar(100) = NULL, @Gender nvarchar(50) = NULL, @Salary int = NULL As Begin Declare @sql nvarchar(max) Set @sql = 'Select * from Employees where 1 = 1' if(@FirstName is not null) Set @sql = @sql + ' and FirstName=''' + @FirstName + '''' if(@LastName is not null) Set @sql = @sql + ' and LastName=''' + @LastName + '''' if(@Gender is not null) Set @sql = @sql + ' and Gender=''' + @Gender + '''' if(@Salary is not null) Set @sql = @sql + ' and Salary=''' + @Salary + '''' Execute sp_executesql @sql End Go Add a Web Page to the project that we have been working with in our previous video. Name it "DynamicSQLInStoredProcedure.aspx". Copy and paste the HTML and code available on my blog at the following link http://csharp-video-tutorials.blogspot.com/2017/04/dynamic-sql-in-stored-procedure.html At this point, run the application and type the following text in the "Firsname" text and click "Search" button. Notice "SalesDB" database is dropped. Our application is prone to SQL injection as we have implemented dynamic sql in our stored procedure by concatenating strings instead of using parameters. ' Drop database SalesDB -- In the following stored procedure we have implemented dynamic sql by using parameters, so this is not prone to sql injecttion. This is an example for good dynamic sql implementation. Create Procedure spSearchEmployeesGoodDynamicSQL @FirstName nvarchar(100) = NULL, @LastName nvarchar(100) = NULL, @Gender nvarchar(50) = NULL, @Salary int = NULL As Begin Declare @sql nvarchar(max) Declare @sqlParams nvarchar(max) Set @sql = 'Select * from Employees where 1 = 1' if(@FirstName is not null) Set @sql = @sql + ' and [email protected]' if(@LastName is not null) Set @sql = @sql + ' and [email protected]' if(@Gender is not null) Set @sql = @sql + ' and [email protected]' if(@Salary is not null) Set @sql = @sql + ' and [email protected]' Execute sp_executesql @sql, N'@FN nvarchar(50), @LN nvarchar(50), @Gen nvarchar(50), @sal int', @[email protected], @[email protected], @[email protected], @[email protected] End Go On the code-behind page, use stored procedure spSearchEmployeesGoodDynamicSQL instead of spSearchEmployeesBadDynamicSQL. We do not have to change any other code. At this point run the application one more time and type the following text in the "Firstname" textbox and click the "Search" button. ' Drop database SalesDB -- Notice "SalesDB" database is not dropped, So in this case our application is not succeptible to SQL injection attack. Summary : Whether you are creating dynamic sql in a client application (like a web application) or in a stored procedure always use parameters instead of concatnating strings. Using parameters to create dynamic sql statements prevents sql injection.

Debugging sql server stored procedures

debugging in ssms debugging t-sql code t sql debug stored procedure sql server management studio debug stored procedure how to debug t sql debug in sql server management studio In this video we will discuss how to debug stored procedures in SQL Server. Setting up the Debugger in SSMS : If you have connected to SQL Server using (local) or . (period), and when you start the debugger you will get the following error Unable to start T-SQL Debugging. Could not connect to computer. To fix this error, use the computer name to connect to the SQL Server instead of using (local) or . For the examples in this video we will be using the following stored procedure. Create procedure spPrintEvenNumbers @Target int as Begin Declare @StartNumber int Set @StartNumber = 1 while(@StartNumber [ @Target) Begin If(@StartNumber%2 = 0) Begin Print @StartNumber End Set @StartNumber = @StartNumber + 1 End Print 'Finished printing even numbers till ' + RTRIM(@Target) End Connect to SQL Server using your computer name, and then execute the above code to create the stored procedure. At this point, open a New Query window. Copy and paste the following T-SQL code to execute the stored procedure. DECLARE @TargetNumber INT SET @TargetNumber = 10 EXECUTE spPrintEvenNumbers @TargetNumber Print 'Done' Starting the Debugger in SSMS : There are 2 ways to start the debugger 1. In SSMS, click on the Debug Menu and select Start Debugging 2. Use the keyboard shortcut ALT + F5 At this point you should have the debugger running. The line that is about to be executed is marked with an yellow arrow Step Over, Step into and Step Out in SSMS : You can find the keyboard shortcuts in the Debug menu in SSMS. Let us understand what Step Over, Step into and Step Out does when debugging the following piece of code 1. There is no difference when you STEP INTO (F11) or STEP OVER (F10) the code on LINE 2 2. On LINE 3, we are calling a Stored Procedure. On this statement if we press F10 (STEP OVER), it won't give us the opportunity to debug the stored procedure code. To be able to debug the stored procedure code you will have to STEP INTO it by pressing F11. 3. If the debugger is in the stored procedure, and you don't want to debug line by line with in that stored procedure, you can STEP OUT of it by pressing SHIFT + F11. When you do this, the debugger completes the execution of the stored procedure and waits on the next line in the main query, i.e on LINE 4 in this example. To stop debugging : There are 2 ways to stop debugging 1. In SSMS, click on the Debug Menu and select Stop Debugging 2. Use the keyboard shortcut SHIFT + F5 Show Next Statement shows the next statement that the debugger is about to execute. Run to Cursor command executes all the statements in a batch up to the current cursor position Locals Window in SSMS : Displays the current values of variables and parameters If you cannot see the locals window or if you have closed it and if you want to open it, you can do so using the following menu option. Locals window is only available if you are in DEBUG mode. Watch Window in SSMS : Just like Locals window, Watch window is used to watch the values of variables. You can add and remove variables from the watch window. To add a variable to the Watch Window, right click on the variable and select "Add Watch" option from the context menu. Call Stack Window in SSMS : Allows you to navigate up and down the call stack to see what values your application is storing at different levels. It's an invaluable tool for determining why your code is doing what it's doing. Immediate Window in SSMS : Very helpful during debugging to evaluate expressions, and print variable values. To clear immediate window type ]cls and press enter. Breakpoints in SSMS : There are 2 ways to set a breakpoint in SSMS. 1. By clicking on the grey margin on the left hand side in SSMS (to remove click again) 2. By pressing F9 (to remove press F9 again) Enable, Disable or Delete all breakpoints : There are 2 ways to Enable, Disable or Delete all breakpoints 1. From the Debug menu 2. From the Breakpoints window. To view Breakpoints window select Debug =] Windows =] Breakpoints or use the keyboard shortcut ALT + CTRL + B Conditional Breakpoint : Conditional Breakpoints are hit only when the specified condition is met. These are extremely useful when you have some kind of a loop and you want to break, only when the loop variable has a specific value (For example loop varible = 100). How to set a conditional break point in SSMS : 1. Right click on the Breakpoint and select Condition from the context menu 2. In the Breakpoint window specify the condition Text version of the video http://csharp-video-tutorials.blogspot.com/2015/09/debugging-sql-server-stored-procedures.html Slides http://csharp-video-tutorials.blogspot.com/2015/09/debugging-sql-server-stored-procedures_28.html

Proper rfc 4122 uuids as guids in wordpress bjrn johansen. Or if every human on earth generated 600,000,000 guids there would only be a 50. When identifiers are used solely within a database, their generation should be left starting with java 5, the uuid class provides simple means for generating uuids have many applications. 20 jul 2009 in other words, only after generating 1 billion uuids every second for the next 100 years, the probability of creating just one duplicate would be about 50. Uuids and linux everything you ever need to know [update uuid (java platform se 7 ) oracle help center.

What is Dynamic SQL 2. Simple example of using Dynamic SQL What is Dynamic SQL Dynamic SQL is a SQL built from strings at runtime. Simple example of using Dynamic SQL Here is the SQL Script to create Employees table and populate it with data Create table Employees ( ID int primary key identity, FirstName nvarchar(50), LastName nvarchar(50), Gender nvarchar(50), Salary int ) Go Insert into Employees values ('Mark', 'Hastings', 'Male', 60000) Insert into Employees values ('Steve', 'Pound', 'Male', 45000) Insert into Employees values ('Ben', 'Hoskins', 'Male', 70000) Insert into Employees values ('Philip', 'Hastings', 'Male', 45000) Insert into Employees values ('Mary', 'Lambeth', 'Female', 30000) Insert into Employees values ('Valarie', 'Vikings', 'Female', 35000) Insert into Employees values ('John', 'Stanmore', 'Male', 80000) Go One way to achieve this is by implementing a stored procedure as shown below that this page would call. Create Procedure spSearchEmployees @FirstName nvarchar(100), @LastName nvarchar(100), @Gender nvarchar(50), @Salary int As Begin Select * from Employees where (FirstName = @FirstName OR @FirstName IS NULL) AND (LastName = @LastName OR @LastName IS NULL) AND (Gender = @Gender OR @Gender IS NULL) AND (Salary = @Salary OR @Salary IS NULL) End Go The stored procedure in this case is not very complicated as we have only 4 search filters. What if there are 20 or more such filters. This stored procedure can get complex. To make things worse what if we want to specify conditions like AND, OR etc between these search filters. The stored procedure can get extremely large, complicated and difficult to maintain. One way to reduce the complexity is by using dynamic SQL as show below. Depending on for which search filters the user has provided the values on the "Search Page", we build the WHERE clause dynamically at runtime, which can reduce complexity. However, you might hear arguments that dynamic sql is bad both in-terms of security and performance. This is true if the dynamic sql is not properly implemented. From a security standpoint, it may open doors for SQL injection attack and from a performance standpoint, the cached query plans may not be reused. If properly implemented, we will not have these problems with dynamic sql. In our upcoming videos, we will discuss good and bad dynamic sql implementations. For now let's implement a simple example that makes use of dynamic sql. In the example below we are assuming the user has supplied values only for FirstName and LastName search fields. To execute the dynamicl sql we are using system stored procedure sp_executesql. sp_executesql takes two pre-defined parameters and any number of user-defined parameters. @statement - The is the first parameter which is mandatory, and contains the SQL statements to execute @params - This is the second parameter and is optional. This is used to declare parameters specified in @statement The rest of the parameters are the parameters that you declared in @params, and you pass them as you pass parameters to a stored procedure Declare @sql nvarchar(1000) Declare @params nvarchar(1000) Set @sql = 'Select * from Employees where [email protected] and [email protected]' Set @params = '@FirstName nvarchar(100), @LastName nvarchar(100)' Execute sp_executesql @sql, @params, @FirstName='Ben',@LastName='Hoskins' This is just the introduction to dynamic SQL. If a few things are unclear at the moment, don't worry. In our upcoming videos we will discuss the following 1. Implementing a real world "Search Web Page" with and without dynamic SQL 2. Performance and Security implications of dynamic sql. Along the way we will also discuss good and bad dynamic sql implementations. 3. Different options available for executing dynamic sql and their implications 4. Using dynamic sql in stored procedures and it's implications Once we discuss all the above, you will understand 1. The flexibility dynamic sql provides 2. Advantages and disadvantages of dynamic sql 3. When and when not to use dynamic sql

Exploring Document Formats in Oracle UPK Developer - UPK Tutorials
 
05:23
http://www.itconvergence.com/oracle-upk-user-productivity-kit - This UPK Video is about Exploring Document Formats in Oracle UPK Developer. This UPK video is part of User Productivity Kit (UPK) Video Tutorial Series from IT Convergence. Here is the transcript of this tutorial: Hello and welcome to the IT convergence's User Productivity Kit tutorial series. This is the demonstration of what options are available for the different document formats when publishing content using the Oracle UPK developer. The UPK developer allows the user to publish content through various document formats which are predefined documents that can appear in Microsoft Word .doc or .docx and Adobe Acrobat .pdf formats. There are several document output options available for publishing in the Publishing Wizard. In this tutorial we're going to walk you through different options available into which document formats they apply. In this demonstration the first document we're going to talk about is a system process document. Each document output uses the text from a specific mode under this option. You can specify the mode text to use. This is applicable for the format system process, job aid, training guide, instructor manual, test document, test case and presentation. Screenshots are included in the document based on the settings for the topic in the topic editor includes screenshots option allows you to over add those settings. This is applicable for the formats: system process, job aid, training guide, instructor manual and test document. Convert screenshots to color reduces the number of colors used in the screenshot as well as the size of the published topic and improves the playback speed. This is applicable for the formats: system process, job aid, training guide, instructor manual, test document test case and presentation. Alternative action and path appear in the document presentation outputs. The Include alternative option allows you to disable this option and makes the output simpler with only one set of steps. This is applicable for the formats: system process, job aid, training guide, instructor manual, test document, test case, and presentation. If you select to include images from packages option. Images will appear if they are attached to a frame or to the concept paint. This is applicable for the formats: system process, training guide, and instructor manual. If you select to include images in a web page option, images will appear if they're attached to the frame or to the concept paint. This is applicable for the formats: system process, training guide and instructor manual. If the include relative links option is disabled, relative links will be excluded from the printed outputs. This is applicable for the formats: system process, job aid, training guide, instructor manual, test document and presentation. Choose an output format you want to publish the output. This is applicable for the format system process, job aid, training guide, instructor manual and, test document. Select Microsoft file type applicable for your version. This is applicable for the formats: system process, job aid, training guide, instructor manual, test document, test case and presentation. The paper size is set based on the location settings in the Regional and Language Options for your operating system locale. By selecting a different paper size, you can overwrite this setting. This is applicable for the formats: system process, job aid, training guide, instructor manual and test document, the using coded fill folder and file names option publishes the content using the document GUID instead of the actual module section in topic names including shortened path names prevents the possibility of duplicated file names in the published output. This option makes it more difficult to identify the source based on the file name. This is applicable for the formats: system process, job aid, training guide, instructor manual, test document, test case and presentation. Next we're going to look at the training guide. Disabling the included assessment option excludes assessments. This is applicable for the formats: training guide and instructor manual. Disable the include questions option to exclude questions. This is applicable for the formats: training guide and instructor manual. Next let's look at the test case document. Each action appears in a separate row in the test procedure table when the group action by context ID option is selected the actions with the same context idea are grouped together into one test step. This is applicable for the test case format. Next let's look at the presentation format. The include action areas option allows you to include a marquee around the action area for each frame. This is applicable for the presentation format.
