SQL with Oracle 10g XE - Using INSERT to Add Data to a Table
 
06:20
In this video I use the INSERT command to add an entire record into a table. When using the command you must also use the keyword VALUES. If you want to enter a null value (one that has no value) for a field you can use the keyword NULL. Be sure to put single quotes around data types that are not numbers. Values need to be entered in the order the fields appear in the table. The commands I used are: INSERT INTO BOOKS VALUES (1,'140231862','9780140231861','The Winter King: A Novel of Arthur','Fiction','14.99','P',1996,1,2) INSERT INTO BOOKS VALUES ('2','140232478','9780140232479','Enemy of God: A Novel of Arthor','Fiction',14.99,'P','1997',1,2); INSERT INTO BOOKS VALUES ('3','140232877','9780140232875','Excalibur: A Novel of Arthor','Fiction',14.99,'P','1998',1,2); INSERT INTO BOOKS VALUES ('4','6513840','9780006513841','Harlequin: Grail Quest','Fiction',19.99,'P','2001',1,1); INSERT INTO BOOKS VALUES ('5','6513859','9780006513858','Vagabond: Grail Quest','Fiction',19.99,'P','2003',1,1); INSERT INTO BOOKS VALUES ('6','7149891','9780007149896','Heretic: Grail Quest','Fiction',19.99,'P','2004',1,1); INSERT INTO BOOKS VALUES ('7','553103547','9780553103540','A Game of Thrones','Fiction',13.99,'H','1996',2,4); INSERT INTO BOOKS VALUES ('8','553801473','9780553801477','A Dance with Dragons','Fiction',13.99,'H','2010',2,5); INSERT INTO BOOKS VALUES ('9','055357342X','9780553573428','A Storm of Swords','Fiction',4.99,'P','2003',2,4); INSERT INTO BOOKS VALUES ('10','1596590424','9781596590427','50 Success Classics','Audio',17.99,NULL,NULL,3,3) INSERT INTO AUTHOR VALUES (1,'Cornwell','Bernard'); INSERT INTO AUTHOR VALUES (2,'Martin','George'); INSERT INTO AUTHOR VALUES (3,'Butler','Tom'); INSERT INTO PUBLISHER VALUES (1,'HarperCollins Publishers Canada, Limited'); INSERT INTO PUBLISHER VALUES (2,'Penguin Books Canada, Limited'); INSERT INTO PUBLISHER VALUES (3,'Gildan Media Corp'); INSERT INTO PUBLISHER VALUES (4,'Bantam Dell Pub Group'); INSERT INTO PUBLISHER VALUES (5,'Spectra'); This video is part of a series of videos with the purpose of learning the SQL language.

We can also say that SQL tables are kind of data structure which are used by database for efficient storage of data. To create a table in our database we use SQL CREATE TABLE command. SQL CREATE TABLE is a type of DATA DEFINITION LANGUAGE also known as DDL. To Create a table in your schema you will require CREATE TABLE system privilege. In our future videos we will see what are system and object privileges and how to grant them to a user. Today for this video we will be using Sample schema HR which already has all the necessary privileges. Ohk Let's see the syntax. CREATE TABLE table name ( column name1 Data-Type(size), column name2 Data-Type(size), ..... ); CREATE TABLE is an oracle reserved word or say an Oracle key word whereas There are 3 different ways of creating a table in Oracle database. Creating a table using Command Line Interface (CLI) in Oracle database For demonstrating how to create table in oracle database using CLI, I'll be using Command prompt. Thats how we create table using command prompt. you can check your table structure by DESCRIBE command for that just write DESC and your table name. Like this Another way of creating a table is by using Graphic user interface (GUI) in Oracle database To demonstrate how to create table using GUI we will use SQL developer. Lets open our SQL developer I am connected to HR schema if you do not know how to create a connection to database using SQL developer please watch my oracle database tutorial 4 that explains database connectivity using SQL developer and command prompt. Link for this video is in the description below. So lets create a table. Creating a table using SQL developer is very easy we do not have to fire any query here. Let's start First of all right click on your connection in which you want to create a table and choose schema browser. This will open a separate schema browser pane or you can expend your connection by clicking this + sign and then right click on table and choose New Table. However I prefer working with schema browser so let's skip to schema browser pane here from the first drop-down list you can choose connection name and in the second drop down list you can choose what database objects you want to work with we want to create a table thus I'll choose table and then click this arrow here and choose option for new table Ok we have created a table wizard first of all give a unique name to your table and add some column as well. For this, click the green plus button. Now we already have a column so give it some name. Also choose a datatype from the list and specify any size you can check this not null column if in case you want to make this a mandatory column you can also specify default value and constraint If you want to make this column a primary key you can click here In my future video i'll show you what are these constraints and different ways of applying them on a column in a table. for this video we will concentrate on create table only so when you are done with all your columns click ok Thats your table You can double click on your table here and can see its structure. Thats it

Oracle SQL PLSQL 12C Tutorial 7   How to Insert Record or Data in Table
 
04:24
This Video Tutorial Will Describe how to insert values or data into the table in oracle 12C version. This command will also work on other versions of database like Oracle 11g Database, Oracle 10g Database, Oracle 9i Database, Oracle 8i Database, Oracle 8 Database and so on. Whenever you create a new table in oracle, you need to insert some data into that table otherwise that table is not usable. Example to select data, to update data and delete data, you first need to insert some data. Full Syntax will be given in this video tutorial about how to insert records in oracle database table. Along with the live example to insert records. All the keywords, format, mandatory clauses etc are described in this video. In this video, I use the INSERT command to add an entire record into a table. When using the command you must also use the keyword VALUES. If you want to enter a null value (one that has no value) for a field you can use the keyword NULL. Be sure to put single quotes around data types that are not numbers. Values need to be entered in the order the fields appear in the table.

SQL with Oracle 10g XE - Using ALTER TABLE to Modify Table Columns
 
05:23
In this video I use the ALTER TABLE command to modify an existing field column. The command will allow you to change the data types, whether the field can be null, or even the primary key. When using the ALTER TABLE command you would use the keyword MODIFY to make changes to an existing column. Be careful when changing a data type of the null field as existing data may cause an error if not in compliance with the new change. The code I used to alter the Books table is : ALTER TABLE BOOKS MODIFY ISBN_10 VARCHAR(13); This video is part of a series of videos with the purpose of learning the SQL language.

We will start with Simple primary key. You can create Primary key either with Create Table statement of by using Alter table Statement. Let's define simple primary key using create table statements. With create table statement we can either define primary key at column level or at table level. We will start with defining Primary key at column level using create table statement. You just have to put keyword Primary key after data type and size of column while defining a column of a table. Here oracle server will create a primary key on product id with default constraint name which will be slightly difficult to understand. You can give your own name to your constraint which is also a good practice.

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#'

We've also added some practice exercises that you can try for yourself. Description The Oracle INSERT statement is used to insert a single record or multiple records into a table in Oracle. Syntax The syntax for the Oracle INSERT statement when inserting a single record using the VALUES keyword : Parameters or Arguments table The table to insert the records into. column1, column2, ... column_n The columns in the table to insert values. expression1, expression2, ... expression_n The values to assign to the columns in the table. So column1 would be assigned the value of expression1, column2 would be assigned the value of expression2, and so on. source_table The source table when inserting data from another table. WHERE conditions Optional. The conditions that must be met for the records to be inserted. Note When inserting records into a table using the Oracle INSERT statement, you must provide a value for every NOT NULL column. You can omit a column from the Oracle INSERT statement if the column allows NULL values. .----------------------------------------------------------------------------------------------------------. video courses- list of playlist : tips and trics link► https://www.youtube.com/playlist?list=PLOfLYVXrwqXrI5jvwUEi6N13QR4xCj2k2 command prompt commands: link►https://www.youtube.com/playlist?list=PLOfLYVXrwqXobXGUdGk6JhzyQ216dNiQL oracle sql: link►https://www.youtube.com/playlist?list=PLOfLYVXrwqXqoUWCoh4cARGDW13SofDO- c programming: link►https://www.youtube.com/playlist?list=PLOfLYVXrwqXrZ_Ub8EXeLY7YP1YxhoJzf .-----------------------------------------------------------------------------------------------------------. watch more videos: learn oracle sql online overview tutorail : https://www.youtube.com/watch?v=Dfesgj4w8QA&t=8s how to fix or repair a corrupted usb flash drive or cd card using command prompt: https://www.youtube.com/edit?video_id... how to copy a folder using cmd: https://www.youtube.com/watch?v=Lblhb... how to move a folder using cmd: https://www.youtube.com/watch?v=YFfHZ... how to dell files in cmd: https://www.youtube.com/watch?v=3-lqg... how to make and remove directory: https://www.youtube.com/edit?video_id... how to change color and title in cmd: https://www.youtube.com/edit?video_id... how to change directory in command prompt: https://www.youtube.com/watch?v=SmLYx... .-----------------------------------------------------------------------------------------------------------. social media links: join our group: ► https://www.facebook.com/groups/24299... ► Follow on Google+: http://[email protected] ► Follow on Twitter: https://twitter.com/@rananavi4766669 :

Oracle SQL Tutorial 11 - CREATE TABLE
 
05:04
The way you create a table is to use the CREATE TABLE command. CREATE TABLE users() So in this situation, the name comes right after the TABLE keyword. The next thing we do is put all of the columns on a line that we want to put in our table. CREATE TABLE users( user_id, username, first_name, last_name ) Notice the naming conventions here. For this series we are going to make columns with what is known as snake casing. This is where each individual word is separated by an underscore. if you have more than one column, all of them have to have commas except the last one. The comma is a way to say that another column is coming, so you don't need to do it on the last one. Now you would think we were done, but we also have to say what data type each column is. Later we will extensively discuss data types so we can focus on them exclusively. For now, here are the data types we are going to use: CREATE TABLE users( user_id NUMBER, username VARCHAR2(50), first_name VARCHAR2(50), last_name VARCHAR2(50) ) Now, inside of the parenthesis for varchar2, we pass in a number... This is the max length of the string. But the question is, what is it measured in? The default is actually in bytes, not characters. For example if we have the string hello, it is 5 characters, but it might take up a total of 10 bytes of storage. So I would recommend adding the keyword char right after the number so it defaults to 50 characters, not bytes. CREATE TABLE users( user_id NUMBER, username VARCHAR(50 CHAR), first_name VARCHAR2(50 CHAR), last_name VARCHAR2(50 CHAR) ) This will work to create a table, but it's really missing a lot of information… which column is the primary key? Are we adding any indexes? Is there any thing else we need to say about these columns? So as you can tell, we are making progress, but there is still so much to learn. The biggest gotcha to remember from this video is that the data type VARCHAR ends in a 2, stupid, right? who would end the name of something with a 2? Once again, this is Caleb from CalebTheVideoMaker2, and we will catch you in the next one! ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ HELP ME! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

Creating a database, table, and inserting - SQLite3 with Python 3 part 1
 
10:59
Welcome to an SQLite mini-series! SQLite, as the name suggests, is a lite version of an SQL database. SQLite3 comes as a part of the Python 3 standard library. Databases offer, typically, a superior method of high-volume data input and output over a typical file such as a text file. SQLite is a "light" version that works based on SQL syntax. SQL is a programming language in itself, but is a very popular database language. Many websites use MySQL, for example. SQLite truly shines because it is extremely lightweight. Setting up an SQLite database is nearly instant, there is no server to set up, no users to define, and no permissions to concern yourself with. For this reason, it is often used as a developmental and protyping database, but it can and is used in production. The main issue with SQLite is that it winds up being much like any other flat-file, so high volume input/output, especially with simultaneous queries, can be problematic and slow. You may then ask, what really is the difference between a typical file and sqlite. First, SQLite will let you structure your data as a database, which can easily be queried, so you get that functionality both with adding new content and calling upon it later. Each table would likely need its own file if you were doing plain files, and SQLite is all in one. SQLite is also going to be buffering your data. A flat file will require a full load before you can start querying the full dataset, SQLite files don't work that way. Finally, edits do not require the entire file to be re-saved, it's just that part of the file. This improves performance significantly. Alright great, let's dive into some SQLite. https://pythonprogramming.net/sql-database-python-part-1-inserting-database/ Playlist: https://www.youtube.com/playlist?list=PLQVvvaa0QuDezJh0sC5CqXLKZTSKU1YNo https://pythonprogramming.net https://twitter.com/sentdex https://www.facebook.com/pythonprogramming.net/ https://plus.google.com/+sentdex

Oracle SQL Tutorial 18 - How to Create Foreign Keys
 
07:09
In this video we are going to be creating foreign keys. I highly recommend watching the previous video before you watch this one. Essentially, we are creating a very simple database for a system where we can create projects and add people to those projects. We started with the users table: --Delete the table if needed: --DROP TABLE users; CREATE TABLE users( user_id NUMBER, username VARCHAR2(50 CHAR) UNIQUE, CONSTRAINT users_pk PRIMARY KEY (user_id) ); Now we are going to create a table for projects with a column that is a foreign key to the username. We're going to want to make this match data types: CREATE TABLE projects( project_id NUMBER, project_name VARCHAR2(50 CHAR) UNIQUE, creator VARCHAR2(50 CHAR) ) Next, we need to add the column attributes we decided on last video: CREATE TABLE projects( project_id NUMBER, project_name VARCHAR2(50 CHAR) UNIQUE, creator VARCHAR2(50 CHAR) NOT NULL ) NOT NULL because we want every project to have a creator, but we are not labeling UNIQUE because that means we could only have a specific username once in the table. We want to allow a user to create multiple projects. We also need to add a primary key: CREATE TABLE projects( project_id NUMBER, project_name VARCHAR2(50 CHAR) UNIQUE, creator VARCHAR2(50 CHAR) NOT NULL, CONSTRAINT projects_pk PRIMARY KEY (username) ) Now, the question that remains is, how can I tell Oracle that I want the username to reference the username column of the other table? We have to make a foreign key constraint. As you've learned from the previous videos, there are about three ways to create constraints. You can do it inline at the column level, unnamed. You can do it at the column level, named, and you can do it at the Table level, named. Usually the table-level is preferred, but I will quickly remind you how to do all three again. CREATE TABLE projects( project_id NUMBER, project_name VARCHAR2(50 CHAR) UNIQUE, creator VARCHAR2(50 CHAR) NOT NULL REFERENCES users (username), CONSTRAINT projects_pk PRIMARY KEY (project_id) ) This works, but if we want to name it, we should do this: CREATE TABLE projects( project_id NUMBER, project_name VARCHAR2(50 CHAR) UNIQUE, creator VARCHAR2(50 CHAR) NOT NULL CONSTRAINT projects_users_fk REFERENCES users (username), CONSTRAINT projects_pk PRIMARY KEY (project_id) ) This works, but the preferred method is to do it at the table level: CREATE TABLE projects( project_id NUMBER, project_name VARCHAR2(50 CHAR) UNIQUE, creator VARCHAR2(50 CHAR) NOT NULL, CONSTRAINT projects_pk PRIMARY KEY (project_id), CONSTRAINT projects_users_fk FOREIGN KEY (creator) REFERENCES users (username) ) Great! So you've learned how to create a foreign key, now we can see it inside of Oracle SQL Developer. One important thing when it comes to foreign keys is what happens when have data in your database and you try to delete the parent row that a row in the child table references? In the next video we are going to configure that using ON DELETE. See you all then and if you enjoy this series, please do me a huge favor by liking the video and subscribing to my YouTube channel. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ HELP ME! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

SQL Into - How to Copy Table Data with Select Into Statement - SQL Training Online
 
05:08
http://www.sqltrainingonline.com SQL Into - How to Copy Table Data with Select Into Statement - SQL Training Online In this video, I show you how to copy data using the SQL INTO statement. Including a trick to copy only a table schema in SQL Server. How do you copy a whole table in SQL Server? You often see the SQL INTO statement when you are using INSERT, but there is a special INTO statement in SQL Server that is used with the SELECT statement that allows you to make a copy of a table for development, testing, or whatever purpose you can think of. So, to start, let's take a look at the SQL Training Online Simple DB employee table. You can see that we have 14 records Now, all we have to do to make a copy of the table is to simply add the SQL INTO clause: SELECT * INTO EMPLOYEE_TEST FROM EMPLOYEE If we run that, you see that we made a copy of the table with all of the data. Now, I want to go ahead and empty the employee_test table and show you how to use the INSERT INTO. If you already have a copy of the table, (I will show you a shortcut in a minute on how to create a copy without data.) then you can use the following insert into statement: INSERT INTO EMPLOYEE_TEST SELECT * FROM EMPLOYEE After running that statement, you see that I have inserted data from the Employee table into the employee_test table. This is sometimes referred to as INSERT INTO SELECT. But, there is one trick that I have used throughout the years that is pretty cool. Sometimes, you want the table schema, but you don't want the data. Now, I know that you can use Management Studio to script out the table for you, but there is an easier way that is more flexible as far as I am concerned. That is to use the SELECT INTO FROM, but put the following in the WHERE clause: SELECT * INTO EMPLOYEE_TEST FROM EMPLOYEE WHERE 1=2 The 1=2 makes is so not data will come over, but you get the new table with the right column types. Is that pretty cool? I have found many uses for this over the years. Let me know what you think bellow.

This is a home work about database where the goal is create something which automatically fill a table with data. So, for this, the idea was simulate a clock (table clock) and sound (table for sound of the clock 'tic' - 'tac'). The procedure insert the minutes at table clock and the trigger insert the sound at de table sound. The job control the time (minutes) to initiate the procedure and the trigger insert the sound at every procedure execution. I hope you find it funny best regards

Foreign key represent a link or say a relationship between columns of tables. Similar to primary key constraint Foreign Key constraint is also of two types. Simple Foreign key constraint and Composite Foreign key constraint. Constraint which involves only one column in foreign key in child table and one column in reference key in parent table is called Simple Foreign Key. While the constraint which involves more than one column in foreign key in child table and more than one column in reference key in the parent table is called Composite Foreign Key.

How to Insert Alternative Actions in UPK Developer - UPK Tutorials - UPK Videos
 
02:42
http://www.itconvergence.com/oracle-upk-user-productivity-kit - This UPK Video is about How to Insert Alternative Actions in Oracle UPK Developer . This UPK video is part of Oracle 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 how to insert an alternative action while using the Oracle UPK developer. Often there's more than one way to accomplish a given task. For instance to save in Microsoft Word document you can click on the File menu in the taskbar and then click Save. Or you can click the Save icon in the toolbar or you can just type control as. All three actions to save the document and there's no one correct way. Alternative actions allow you to document the multiple ways to perform task and icon will appear in the bubble text that alerts the user when there is no alternative way of performing their task. First start by opening an existing topic, select the frame where you want to insert an alternative action, click on Insert and then select alternative action from the drop down list. After creating an alternative action UPK developer will minimize and a recorder will appear. Ensure that you are on the same step of the process and press print screen to begin recording. Perform the alternative action to complete this step the recorder will capture the action and automatically close and then UPL developer will reopen. No. Alternative actions will only record one action. If you want to record multiple steps, insert alternative path the frame for the alternative action will not display a number of actions available. This will appears a fraction above the frame. To toggle between the actions, select the frame and press all down or press all up. No, only the default action will display in the see it mode. If you decide that you want to the end user to view the alternative action instead of the primary action you can set the new default action to do so. Ensure you are on the frame containing the alternative action click on the Edit menu and select Set as default. To delete not alternative action press the Delete button from the toolbar and choose the Delete action. Click Yes thus it confirm the deletion. No, you cannot delete both actions you must leave at least one action item. If you decide that you do not like either action, you can either edit the action area or you can delete the entire and re-record the action. This concludes our tutorial on how to insert an alternative action in the Oracle UPK developer. On behalf of IT Convergence, I would like to thank you for your time and invite you to join the IT Convergence YouTube channel where you can learn more about the User Productivity Kit features and functions. Thank you!
