Working with dates in Oracle PLSQL.
 
23:34
Dates in Oracle PL SQL is definitely the most powerful among all other databases. It gives us full flexibility to manipulate it of our choice, whether you are calculating days, months or year, printing date and time in various format. Useful date functions add_months, months_between, last_day, next_day and to_char helps us a lot in handling date time in our pl sql programming.

Oracle TO_TIMESTAMP Function
 
01:31
https://www.databasestar.com/oracle-to_timestamp/ The Oracle TO_TIMESTAMP function can be confusing, but we’ll explain it in this video. This function allows you to convert a string value into a TIMESTAMP value. A TIMESTAMP value is a type of DATE, but has a few components: - A date, including day, month, and year - A time, including hours, minutes, seconds, and fractional seconds This is a useful data type because it allows you to store a time down to fractions of a second. The syntax of the TO_TIMESTAMP function is: TO_TIMESTAMP ( input_string [, format_mask] [, nls_param] ) The input_string parameter is the string you want to convert. The format_mask is where you specify the format of the input_string parameter. This is so you can specify the input_string in a variety of formats, and just use this format_mask to indicate which format it is in. The nls_param parameter is another optional parameter, and allows you to specify the returning language of the month and day names. The default format will depend on the region you’re running your database in. In my example (using Oracle Express in Australia), the default format is ‘DD-MM-RRRR HH:MI:SS AM’. For more information on the Oracle TO_TIMESTAMP function, including the SQL used in this video, read the related article here: https://www.databasestar.com/oracle-to_timestamp/

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.

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

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!)

Oracle TO_TIMESTAMP_TZ Function
 
01:43
https://www.databasestar.com/oracle-timezone-functions/ The Oracle TO_TIMESTAMP_TZ function can be confusing, but we’ll explain it in this video. This function allows you to convert a string value into a TIMESTAMP WITH TIME ZONE value. A TIMESTAMP WITH TIME ZONE value is a type of DATE, but has a few components: - A date, including day, month, and year - A time, including hours, minutes, and seconds - A time zone, which is the number of hours and minutes difference from GMT This is a useful data type because it allows you to store dates in different time zones, and allow users in other time zones to see the data in a way that makes sense to them. The time zone part is the difference from GMT. This means that a “+7:00” is 7 hours ahead of GMT (e.g. Bangkok) and “-5:00” is 5 hours behind GMT (e.g. US Eastern Standard Time). The syntax of the TO_TIMESTAMP_TZ function is: TO_TIMESTAMP_TZ ( input_string [, format_mask] [, nls_param] ) The input_string parameter is the string you want to convert. The format_mask is where you specify the format of the input_string parameter. This is so you can specify the input_string in a variety of formats, and just use this format_mask to indicate which format it is in. The nls_param parameter is another optional parameter, and allows you to specify the returning language of the month and day names.

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.

Oracle SQL MERGE Statement
 
07:52
https://www.databasestar.com/oracle-merge-sql/ In this video, we’ll learn what the Oracle MERGE statement does and how you can use it. What is the MERGE statement? It’s a statement that lets you either insert or update data in a table - all in a single statement! It’s helpful if you’re using an ETL (Extract Transform Load) process when creating or updating a data warehouse. It’s also helpful when loading data into your own database if you’re not creating a data warehouse. It allows you to prevent duplicate data and ensure you have up-to-date data in your table. The syntax looks like this: MERGE INTO table_name USING table_name ON (condition) WHEN MATCHED THEN update_clause DELETE where_clause WHEN NOT MATCHED THEN insert_clause [LOG ERRORS log_errors_clause reject_limit integer | unlimited ] In this video, I also show an Oracle SQL MERGE statement example, so watch the video to find out more.

Difference between DateTime and DateTime2 in SQL Server
 
10:42
datetime vs datetime2 sql server In this video we will discuss the difference between DateTime and DateTime2 in SQL Server The date range for DateTime is January 1, 1753, through December 31, 9999 where as for DateTime2 it is January 1, 0001, through December 31, 9999 The time range for DateTime is 00:00:00 through 23:59:59.997 where as for DateTime2 it is 00:00:00 through 23:59:59.9999999 Accuracy for DateTime is 3.33 Milli-seconds where as for DateTime2 it is 100 nanoseconds Storage size for DateTime is 8 Bytes where as for DateTime2 it is 6 to 8 Bytes (Depending on the precision required) The default value for both DateTime and DateTime2 is the same - 1900-01-01 00:00:00 DATETIME2 has a bigger date range than DATETIME. Also, DATETIME2 is more accurate than DATETIME. So I would recommend using DATETIME2 over DATETIME when possible. I think the only reason for using DATETIME over DATETIME2 is for backward compatibility. DateTime2 Syntax : DATETIME2 [ (fractional seconds precision) ] With DateTime2 Optional fractional seconds precision can be specified The precision scale is from 0 to 7 digits The default precision is 7 digits For precision 1 and 2, storage size is 6 bytes For precision 3 and 4, storage size is 7 bytes For precision 5, 6 and 7, storage size is 8 bytes Text version of the video http://csharp-video-tutorials.blogspot.com/2015/10/difference-between-datetime-and_21.html Slides http://csharp-video-tutorials.blogspot.com/2015/10/difference-between-datetime-and_20.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

Part 20   Using ROWVERSION or TIMESTAMP to detect concurrency conflicts
 
05:59
Link for all dot net and sql server video tutorial playlists http://www.youtube.com/user/kudvenkat/playlists Link for slides, code samples and text version of the video http://csharp-video-tutorials.blogspot.com/2014/10/part-20-using-rowversion-or-timestamp.html This is continuation to Part 19. Please watch Part 19 before proceeding. In this video we will discuss how to use ROWVERSION or TIMESTAMP columns to detect concurrency conflicts in linq to sql. Let us understand this with an example. By default LINQ to SQL uses all the columns of the table in the WHERE clause to detect concurrency conflicts. The query would look as shown below. exec sp_executesql N'UPDATE [dbo].[Accounts] SET [AccountBalance] = @p3 WHERE ([AccountNumber] = @p0) AND ([AccountName] = @p1) AND ([AccountBalance] = @p2)', N'@p0 int,@p1 nvarchar(4000),@p2 int,@p3 int',@p0=1,@p1=N'John Mary',@p2=1000,@p3=1500 This is OK if we have a few columns in the table. In real time applications we may have tables with large number of columns. For example, what if the table has 30 columns. The WHERE clause would be huge and it can impact the performance of the application. In situations like this we can use ROWVERSION or TIMESTAMP columns. Here are the steps Step 1 : Add a Version column to the Accounts table. The datatype of the column must be either ROWVERSION or TIMESTAMP. The value for this column is automatically generated by the database if the row gets changed. So this column can alone be used to detect concurrency conflicts. ALTER TABLE Accounts ADD [Version] ROWVERSION Step 2 : In Visual Studio, delete the Account Entity from the Sample.dbml file Step 3 : In Server Explorer window in Visual Studio, right click on Accounts table and select "Refresh". Step 4 : Drag and drop Accounts table on the Designer surface of Sample.dbml file. Notice that a Version Property is automatically added. Navigate to Sample.Designer.cs file and look at the code generated for this property. Notice that IsVersion & IsDbGenerated properties are set to true. [global::System.Data.Linq.Mapping.ColumnAttribute(Storage="_Version", AutoSync=AutoSync.Always, DbType="rowversion NOT NULL", CanBeNull=false, IsDbGenerated=true, IsVersion=true, UpdateCheck=UpdateCheck.Never)] public System.Data.Linq.Binary Version { get { return this._Version; } set { if ((this._Version != value)) { this.OnVersionChanging(value); this.SendPropertyChanging(); this._Version = value; this.SendPropertyChanged("Version"); this.OnVersionChanged(); } } } Testing for concurrency conflicts : Let's now simulate the scenario of 2 users updating the same record at the same time. To do this Step 1 : Throw a break point on the line where we call db.SubmitChanges(); in btnDeposit_Click() method. Step 2 : Run the application in Debug mode, and click "Deposit $500" button. The execution should stop on SubmitChanges() method. Step 3 : At this point open SQL Server Management Studio. a) Execute the following SELECT query Select * from Accounts where AccountNumber = 1 b) Notice the Value of Version column c) Execute the following UPDATE query Update Accounts set AccountBalance = AccountBalance - 300 Where AccountNumber = 1 d) Now notice that the Value of Version column is automatically changed to a new value Step 4 : Open SQL Profiler and run a new trace. Step 5 : Now come back to Visual Studio and press F5 to continue the execution. Notice that "ChangeConflictException" is thrown as expected. Step 6 : In SQL Profiler notice that the UPDATE query that is generated has used Version column in the WHERE clause to detect concurrency conflicts. exec sp_executesql N'UPDATE [dbo].[Accounts] SET [AccountBalance] = @p2 WHERE ([AccountNumber] = @p0) AND ([Version] = @p1) SELECT [t1].[Version] FROM [dbo].[Accounts] AS [t1] WHERE ((@@ROWCOUNT) ] 0) AND ([t1].[AccountNumber] = @p3)', N'@p0 int,@p1 timestamp,@p2 int,@p3 int',@p0=1,@p1=0x0000000000002715,@p2=1500,@p3=1

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 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.
