Check Last Modified DateTime for An Object (Table,Stored Procedure,Trigger etc.) in SQL Server
 
04:23
We as SQL Server developers send our DDL Scripts ( Add New Column, Drop some column from table, or Alter Stored Procedure) to DBA. After deployment we verify those changes and sometime it happens that the changes are not done. Maybe DBA has missed one of the script to run. If we can get the last modified date for object ( Table,Stored Procedure, View etc) that can confirm the changes are done on given date. blog post link for scripts used in this video http://sqlage.blogspot.com/2014/01/tsql-how-to-check-when-object-table.html

Oracle TO_DATE Function Explained with Examples
 
06:14
https://www.databasestar.com/oracle-to_date/ The Oracle TO_DATE function is one of the most useful conversion functions in Oracle. It can be a little confusing though. The TO_DATE function is used to convert a character value to a date value. You can use it to convert a string that is in the format of a date, into a date data type. Why would you use this? Converting a character to a date is helpful if you want to insert a date into a column in a table. Being specific about the format (explicit) is better than assuming the conversion will be done for you (implicit). This TO_DATE function only converts to a DATE data type. If you want to convert to the other datetime data types, you’ll have to use other functions such as TO_TIMESTAMP or TO_TIMESTAMP_TZ. The syntax for this function is: TO_DATE(charvalue [, format_mask [, nls_date_language]]) The parameters for this function are: Charvalue: This is the character value that you want to convert to a date. It’s the main input of the function. Format_mask: This is the format that the input value, the charvalue, is in. This is used to help convert your character value into a date, as your character may be in a different format to the default. Nls_date_language: this is used to determine how the output is displayed. For more information about the Oracle TO_DATE function, including all of the SQL shown in this video and the examples, read the related article here: https://www.databasestar.com/oracle-to_date/

MySQL 33 - Datetime, Date, Time Data Types
 
06:40
Next up on our MySQL to-do list is to learn about storing dates and times. There are various data types in MySQL for storing dates and times. It seems MySQL and databases likes to break everything up into multiple data types to make things more organized at the consequence of being confusing and annoying. This video is going to be talking about the DATETIME, DATE, and TIME data types. These are all used to store, you guessed it, dates and times. The one you choose depends on your needs. If you just need dates, choose DATE. If you just need times, choose TIME, if you need both stored together, choose DATETIME. Now you set a column one of these data types whenever you want every row for this field to have some sort of date, time or both…but how exactly is the data formatted? This requires us to understand some convention. For example, in the USA at least, if you have something like 4:30AM, by convention you know the hour is 4 and the minutes are 30. But this is just an agreed upon convention. MySQL has its own convention…For example 2017-02-02. The first thing is the year, the second is the month, and the third is the day. That is for the DATE. The convention for time is 22:54:30. The first is the hour (military time), the second is the minute, and the third is the seconds. Lastly, there can actually be fractions of seconds…up to microseconds! .123456. To use fractional seconds though you must specify to MySQL the precision of the TIME or DATETIME when you create it, for example DATETIME(6) would allow microsecond precision. How do you actually give a date to MySQL? By that I mean let's say you have a table with a column of DATETIME(6), and you want to give a value for that column, how do you format it? It's quoted. For example: '2017-02-02 22:54:30.333333' MySQL interprets this as a DATETIME. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support 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!)

Hibernate Tip: How to use a timestamp for versioning and optimistic locking
 
04:45
Get more recipes like this one in my new book Hibernate Tips: More than 70 solutions to common Hibernate problems: https://goo.gl/XfywNk When you had to map a legacy table model in one of your projects, you probably know this situation. Instead of a numeric version column, the table model uses the timestamp of the last update. I don’t recommend using this approach because numeric versioning is much more efficient. But if you have to, you can also use a timestamp for versioning with JPA and Hibernate. If you like this video, please give me your thumbs up and share it with your friends and co-workers.

Oracle FROM_TZ Function
 
01:45
https://www.databasestar.com/oracle-timezone-functions/ The Oracle FROM_TZ function is used to convert a value in a TIMESTAMP data type, and a specific TIME ZONE, to a TIMESTAMP WITH TIME ZONE value. It’s a helpful conversion function if you work with times and time zones a lot. The syntax of the FROM_TZ function is: FROM_TZ ( timestamp_value, timezone_value ) The parameters of this function are: - timestamp_value: the value in a TIMESTAMP format to convert. - timezone_value: this is the timezone value that the timestamp_value will be converted in to. If you want to know what values can be used as a timezone value, you can look in the database view here: SELECT * FROM v$timezone_names; For more information about the Oracle FROM_TZ function, including all of the SQL shown in this video and the examples, read the related article here: https://www.databasestar.com/oracle-timezone-functions/

Oracle DBTIMEZONE Function
 
01:17
https://www.databasestar.com/oracle-timezone-functions/ The Oracle DBTIMEZONE function returns the database timezone offset of the database. It returns it in the format of +/- TZH:TZM, or the time zone region name. It’s useful to know what timezone the database is in when working with dates and different time zones, as it can impact the queries you write. The syntax for this function is quite simple: DBTIMEZONE There are no parameters - just the function name. You can’t actually change the timezone of the database using this function. It uses the timezone of the operating system of the server the database runs on. It’s similar to the SESSIONTIMEZONE function, but that function returns the timezone of your session and not the database server. It’s also similar to the SYSTIMESTAMP function, but that function returns the date, time, and timezone of the database, where DBTIMEZONE just returns the timezone.

SQL Date Comparison - How to filter Datetime in SQL Server - SQL Training Online
 
08:41
http://www.sqltrainingonline.com SQL Date Comparison - How to filter Datetime in SQL Server - SQL Training Online In this video, I show you how to do a SQL Date Comparison in SQL Server when your Datetime has an actual time in it. I also include the latest trick that will make this easier if you are using SQL Server 2008 or SQL Server 2012. How do you compare a Datetime in SQL Server? A SQL Datetime stores both Date and Time. So when you are filtering using the SQL Where clause, you have to know if you Datetime is storing the time also. Let's take a look at the employee table in SQL Training Online Simple DB The column we are looking at is the hire date. I want to go after the person who was hired on February, 22 2005. So, I use the following SQL. select * from employee where hire_date='02/22/2005' Now, this works because we don't have any times stored in this column. But, if I change the record from 2005-02-22 00:00:00.000 to 2005-02-22 08:22:25.000 and rerun the query, you see that I don't get any results. That is because the value of 02/22/2005 is really 2005-02-22 00:00:00.000 and I just changed the hire_date to include a time other than 00:00:00.000. So, I have to tweak my query to use a greater than and less than sign. This works. But, to really understand what is going on, let me show you what SQL Server really sees. There are other ways, and in this StackOverflow article you can read more about these other ways. But, I want to point out a few. If you are working in SQL Server 2005 or earlier, the following is supposed to be the fastest performing way to do this. select datediff(dd,0, hire_date),* from employee where dateadd(dd,0, datediff(dd,0, hire_date)) = '2005-02-22' But, if you are working in SQL Server 2008 or SQL Server 2012, they have introduced an actual Date datatype that doesn't include the Time portion. Since this is the case, you can use the CAST function to remove the time from the Datetime. Here is the SQL to do that. select * from employee where CAST(hire_date AS Date) = '2005-02-22' And that's it. If you enjoy the video, please give it a like, comment, or subscribe to my channel.

39. Google Firebase  - The behavior for Date objects stored in Firestore is going to change
 
10:23
A video to help understand the following Google Firebase Firestore error: @firebase/firestore: Firestore (5.0.4): The behavior for Date objects stored in Firestore is going to change AND YOUR APP MAY BREAK. To hide this warning and ensure your app does not break, you need to add the following code to your app before calling any other Cloud Firestore methods: const firestore = firebase.firestore(); const settings = {/* your settings... */ timestampsInSnapshots: true}; firestore.settings(settings); With this change, timestamps stored in Cloud Firestore will be read back as Firebase Timestamp objects instead of as system Date objects. So you will also need to update code expecting a Date to instead expect a Timestamp. For example: // Old: const date = snapshot.get('created_at'); // New: const timestamp = snapshot.get('created_at'); const date = timestamp.toDate(); Please audit all existing usages of Date when you enable the new behavior. In a future release, the behavior will change to the new behavior, so if you do not follow these steps, YOUR APP MAY BREAK. This video is part of a playlist: https://www.youtube.com/playlist?list=PLjuQOVlnQv2UxCWdis189jYjZESsYP4vP It is also part of a blog post on DedicatedManagers.com: http://www.dedicatedmanagers.com/real-time-database-with-vue-js-vuex-vuetify-firebase-authentication-firestore/ The source code for this project is available publicly on the Dedicated Managers Github account: https://github.com/DedicatedManagers/vue.vuex.vuetify.firebase-realtime-database

Oracle SQL Tutorial 29 - NCHAR Part 1
 
04:58
NCHAR is another data type available in Oracle database. This data type is very similar to the char data type with some key differences. NCHAR is also known as the national character set. This is a data type that allows us to store Unicode characters. It is really recommended that you watch the two videos over Unicode and UTF-8 because this video is going to talk a lot about it. Why is it that we have an entire data type dedicated to storing Unicode? That will be easily understood once we understand how character sets and encodings are applied to Oracle. They are applied at the database level. That means that you have a character set that applies to the entire database. This is in contrast to some database management systems that allow you to apply a data type at the table and column level. For example, in MySQL you can make a table have a character set, and make a specific column in that table a different character set. That means we can customize everything at the expense of adding potential complexity and confusion. Oracle does not work that way. In Oracle, we define one character set for the entire database. The problem with defining a character set for the entire database is that it may not be the character set we want to use for everything. That is where the NCHAR column comes in. The NCHAR column allows us to have a Unicode column inside of a database that does not use Unicode as the default character set. That is important because it is very often that we want to use Unicode but we may not need to use it for everything, for example if that application is working with ASCII nearly all of the time. If you are using Unicode for the database, then NCHAR is not going to be needed and should not be used. This data type is not as widely accepted, so only use it if you absolutely need to, specifically when you need to store Unicode in a non-Unicode database. Additionally, there is some controversy when it comes to whether or not you should use the CHAR and NCHAR data types in Oracle at all. We will discuss why in an upcoming video. In the next video we are going to go over some specific character sets that Oracle can use.

Oracle SQL Tutorial 24 - Important Data Types
 
06:09
In the upcoming videos we are going to discuss data types in depth, but I don't want to drown you in all of the details. Because of that, I'm giving you this video which is going to introduce you to the most important data types. Then, in the upcoming videos, I'll describe them in more depth. One of the data types we've already discussed in this video is NUMBER. This data type is used to, obviously, store a number. It can be used to store integers (whole numbers), or numbers with decimals. There are two other numeric data types you should know of. BINARY_FLOAT and BINARY_DOUBLE are both numeric data types that are known as floating point numbers. A floating point number is often used for large numbers that have decimal places where it is acceptable to not be completely precise. What I mean by this is that these numbers can only store numbers correctly up to a certain decimal point. If you need perfect precision, you will want to use the NUMBER data type. Now storing numbers is good sometimes, but occasionally you will want to store string data. String data can be any sequence of characters, including numbers. By telling the database that a column is a string data type, the database knows how to treat that column. There are four important string data types that you need to know about. The first two are CHAR and NCHAR. These data types are used to store a fixed-length string. So for example, you can say you want to store 12 characters. This means that every value for this column will be exactly 12 characters. If you insert less than 12 characters, the data will be padded with spaces. This means you will want to use one of these data types when every value in the column is the same length. What is the difference between CHAR and NCHAR? CHAR uses what is known as ASCII while NCHAR uses Unicode. The difference is what characters are allowed and how much space each character takes. ASCII takes up less space but only supports English, numbers, and some symbols. UNICODE allows you to store characters from multiple languages but takes up more space. Those were both fixed-length string. What if you want to store data that changes in length? That is where VARCHAR2 and NVARCHAR2 come in. When it comes to storing dates, the data types that are most important are DATE and TIMESTAMP. Date can be used to store dates and time. Timestamp is a data type that can be used to store an exact moment in time. Lastly, there are interval types. These store a date range. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support 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!)

Oracle SQL Tutorial 33 - NUMBER Data Type
 
07:18
This video we are going to discuss the NUMBER data type. The Number data type is used to store integers, and real numbers. When you create a column as a NUMBER, you can store pretty huge or pretty small numbers in this column. Now there are two things you need to consider when working with numbers, and that is the precision as well as the how big the number is. For example, we can store the number 9.9. This has two significant digits. We could also store the number 9.9 X 10^4. In this situation, the number is much larger, but the number of significant digits is the same. 9.9 are the significant digits. When we expand this out we just have 99000, and the zeros are just used for size and are not considered "significant" in this situation. In fact, you get a max precision of 38, but a maximum value of 9.99 * 10^125. You can also use this data type to store very small numbers. Check the docs for the specifics on maximums and minimums. You can provide it with two pieces of information: Precision - The total number of digits. Scale - The number of digits to the right of the decimal. You do it in this format: NUMBER (precision, scale). The important thing to remember in this is that when you specify a precision, you will be limiting the max size of the numbers. The secret behind this data type is that it is actually stored in scientific notation. That is we store a number and then we can multiply it by 10 raised to some power. This allows us to store much larger numbers without taking up a ton of space. The oracle docs actually gives a formula that you can use to see how much storage is going to be required for a specific NUMBER data type. How much precision can be used? The acceptable range is 1-38. What about scale? The range is actually -84 to 127. I'll explain the scale in more detail in an upcoming video. That's because there is a lot of confusing things here…What does it mean for the scale to be negative? How can we have a scale that is bigger that the total number of digits available through the precision. That's a topic for another video. It's important to understand that when we increase our scale, we decrease the max size of the number. For example if we have a precision of 5 and a scale of 3, the highest number we can store is 99.999. This is in contrast to a precision of 5 and a scale of 2 which allows for up to 99.999. Either way you get 5 significant digits, but the numbers of digits to the left and right of the decimal change. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support 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!)

Oracle CURRENT_DATE Function
 
01:54
https://www.databasestar.com/oracle-date-functions/ The Oracle CURRENT_DATE function is used to return the current date in the session timezone. The session timezone is the timezone that the current user is logging in from. This can be different from the database’s timezone. The syntax of the CURRENT_DATE function is: CURRENT_DATE No parameters are needed - just the function name. The function returns a DATE data type, and it includes hours, minutes, and seconds. This is good to know because the default display format for DATE does not include the time component, and it can be easy to forget. It’s different to the SYSDATE function as SYSDATE returns the date in the database timezone, and CURRENT_DATE returns the date in the session time zone. So, if I’m logging in from Melbourne, Australia, and the database is in London, England, then the CURRENT_DATE will return a date and time that’s 10 hours ahead of SYSDATE. It may be on the same day, or it could be a different day, depending on when I run the function. You can perform arithmetic on this function just like any other date value (e.g. CURRENT_DATE - 7 for 7 days ago). For more information about the Oracle CURRENT_DATE function, including all of the SQL shown in this video and the examples, read the related article here: https://www.databasestar.com/oracle-date-functions/

Custom date time format in Oracle SQL Developer?
 
01:03
From Oracle SQL Developer's menu go to Tools -- Preferences. From the Preferences dialog, select Database -- NLS from the left panel. From the list of NLS parameters, enter DD-MON-RR HH24:MI:SS or for 24-Hour, DD-MON-YY HH24:MI:SS Or just for an active session use below instead. alter SESSION set NLS_DATE_FORMAT = 'required_date_format' i.e. alter SESSION set NLS_DATE_FORMAT = 'DD-MM-YYYY HH24:MI:SS' into the Date Format field. Save and close the dialog.

Oracle SQL Tutorial 23 - Intro to Data Types
 
05:03
Every column within a table has to be given what is known as a datatype. A data type is a fairly simple concept when you dissect the word. It is literally the type of data. Why do we use types, though? The biggest benefit is so that Oracle knows how to interpret and work with our data. It also makes the database better at rejecting incorrect data. If we had to concept of a data type, there would be a lot more work involved in forcing data to be of the right format. It would also be harder for us to get the database to treat the data in the correct way. In addition to this, a database can optimize storage and performance for a column if everything is of the same data type. Because of this, each column can only support one data type. There are numerous different data types in Oracle and it helps us if we categorize them. The first types of datatypes we should learn about are: String, Numeric, Temporal Now, there are few more categories we could make, but these are the main ones. We will worry about the other ones another day as I am only introducing the topic. A string data type is anything within quotes. Most databases use single quotes for string data. Inside of the quotes can be any number of characters. What is a character? Think of any letter, number, or symbol you can type. Some people call these letters, numbers, and symbols alphanumeric. Numeric data type includes only numbers. These data types are often used for data that you plan on using for mathematical calculations. Temporal data types are data types that are used for dates and times. Now, each data type is probably going to have some options you'll need to worry about, but one that comes up with every data type is storage. The reason we need to consider storage is because we may end up with millions of rows in a table and the difference between a few bytes for each row will make a huge difference when we look at the whole picture. When a data type gives you the option of size, you will want to a size that will be able to hold what you need, but nothing more. In the upcoming videos we are going to discuss the available data types in more detail. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support 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!)

Can you flashback table into SYSTEM tablespace?
 
10:02
Flashback feature in Oracle database is well known to roll back the table to a specific timestamp (depends on undo retention) or to restore dropped table and many more. We must have used this flashback feature so far on application schema objects and found working without any issues. As an Oracle DBA did you configure any tools (might be monitoring, RMAN catalog or any) with objects created in SYSTEM tablespace? If so, you probably would see some problems later when you need to use Flashback on these objects though they are not Oracle supplied objects. Let us go through a case study which will clearly explain you the functionality of Flashback table. Did you like the video? Subscribe now, Like it and share it.

Step 1: Go to dbhome --- hostname_SID --- Sysman --- Config --- open emd.properties in notepad and set the value agentTZRegion=+06:00 to the value of your timezone and click save. You can also do it using export and time zone reset commands. Step 2: ALTER DATABASE SET TIME_ZONE='+06:00'; according to your time zone. You can check DB TIME Zone using " select dbtimezone from dual ; ". Step 3: In step 2 if you get the error "ORA-30079: cannot alter database timezone when database has TIMESTAMP WITH LOCAL TIME ZONE columns" then please FOLLOW following steps SQL--- select count (*) from dba_tab_columns 2 where data_type like 'TIMESTAMP%WITH LOCAL TIME ZONE' ; COUNT(*) 1 In this case there is only one table. The owner and name can be determined by: SQL--- select owner, table_name from dba_tab_columns 2 where data_type like 'TIMESTAMP%WITH LOCAL TIME ZONE'; OWNER TABLE_NAME ------------------------------ OE ORDERS SQL--- desc oe.orders ; Name Null? Type -------- ORDER_ID NOT NULL NUMBER(12) ORDER_DATE NOT NULL TIMESTAMP(6) WITH LOCAL TIME ZONE ORDER_MODE VARCHAR2(Cool CUSTOMER_ID NOT NULL NUMBER(6) ORDER_STATUS NUMBER(2) ORDER_TOTAL NUMBER(8,2) SALES_REP_ID NUMBER(6) PROMOTION_ID NUMBER(6) This oe.orders is just a table in the example schema of OE so this colums can be dropped. So please dont install sample schemas if you dont need them. SQL--- alter table OE.ORDERS drop column ORDER_DATE ; Table altered. Now the Time Zone can be altered using above command. Step 4: Also check the value of " SELECT SESSIONTIMEZONE FROM DUAL; " and if the value differs from os time zone, db time zone , emd.properties / agent time zone then also set it according to your timezone but I believe it always gives the OS time zone. Step 5: Stop and Restart all Services and check that Oracle DBConsole service is running or not and if not running then start from command prompt " emctl start dbconsole" . https://hostname:1158/em/
