https://www.databasestar.com/oracle-date-functions/ The Oracle CURRENT_TIMESTAMP function will display the current date and time in the session time zone. Just like the CURRENT_DATE function, it uses the session time zone, which is where you logged in from. This could be different to the database time zone. The syntax of the CURRENT_TIMESTAMP function is: CURRENT_TIMESTAMP ( [precision] ) The return type of this function is TIMESTAMP WITH TIME ZONE. The precision parameter is optional, and it lets you specify the number of fractional seconds to return. If this is omitted, it uses the default of 6. It’s different to the SYSTIMESTAMP function, because CURRENT_TIMESTAMP returns the session timezone, and SYSTIMESTAMP returns the database time zone. So, if I’m logging in from Melbourne, Australia, and the database is in London, England, then the CURRENT_TIMESTAMP will return a date and time that’s 10 hours ahead of SYSTIMESTAMP, and in a different time zone. 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_TIMESTAMP - 7 for 7 days ago). However, it might be better to use interval data types so you can keep the original data type.

Oracle TO_TIMESTAMP Function
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’.

MySQL 33 - Datetime, Date, Time Data Types
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 CURRENT_DATE Function
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).

Check Last Modified DateTime for An Object (Table,Stored Procedure,Trigger etc.) in SQL Server
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
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/

How to Use MySQL Date and Time Functions
Follow this step by step easy tutorial to learn how to use MySQL date and time functions and see how to modify the time formats. Don't forget to check out our site http://howtech.tv/ for more free how-to videos! http://youtube.com/ithowtovids - our feed http://www.facebook.com/howtechtv - join us on facebook https://plus.google.com/103440382717658277879 - our group in Google+ There are various functions which can be used for calculating the date and time in MySQL but for the purpose of this tutorial we will use 3 primary functions for date and time each. For this tutorial, we will be using SQL YOG as an instance of MySQL.  Step 1- Current Date Let's start with MySQL date functions. For that write the following query: select curdate(); and press F5 to execute. It will show the current date of the system. Curdate is a short form of current date. Step 2-Changing date format Now if we want to view the date in a specific format, we can use a function called the date_format(). Write "date_format" function in a similar pattern as before, but this time inside the parentheses, we will write the date within single quotation marks and then specify the required format in single quotations after a comma. Here we are using W for week, M for Month and Y for years which are implicit format specified in the MySQL environment, and used with a percentage sign. The actual query would be: select date_format('2013-04-18','%W %M %Y'); Step 3- Viewing Name of the Day In MySQL date functions library, there is a method which can return the day name, when given the date as its perimeter. It is called "dayname" function. To use that, write dayname(), following the "select" keyword, and specify the date within single quotes inside the parenthesis. The query would be: select dayname('1998-04-25'); Step 4- Time Functions Now let's move on to mysql time functions First of all let's find out the current time. For that, we will write curtime(),which stands for the current time, and write the query in the same way as we did for the current date. Hence the query would be: select curtime(); Step 5- Changing time format Now let's see how we can change the format of the output. For that, use the time_format() function, as we did for the date format. Write the following query in the editor: select time_format('14:28:18','%h : %i : %s'); Over here, h, i and s are used for hours, minutes and seconds respectively. Step 6- Changing Time to Seconds In MyQL time functions library, there are various functions related to time. One of them which is widely used by programmers is the time_to_sec() function. This method changes the given time to seconds. To use this, write time_to_sec() and specify the time inside the parentheses within single quotes. In the Query Editor, write: select time_to_sec('14:28:18'); When we execute the query, we can see that the time being displayed is in seconds. Step 7- Date along with Time Lastly, to display the current date and time altogether, we can use now() function along with the select keyword. Write: select now(); in the query editor and execute it. And this was all about MySQL date & time functions.
Part 20   Using ROWVERSION or TIMESTAMP to detect concurrency conflicts
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

SQL Tutorial - Create Table with Constraints
This video tutorial will show you how to create a table with constraints in Microsoft SQL Server. The video covers, data types of columns, NOT NULL constraints, PRIMARY KEY constraints, FOREIGN KEY constraints, CHECK constraints and DEFAULT constraints. Data types enforce limits to the what can inserted in to tables and constraints further build on this, for example if you wanted to add a column called age, the values will usually range from 0 - 100 so we could choose a data type of TINYINT which allows values of up to 255 but this means if you enter 255 this is still a valid age. We want to control this even further so we can add a CHECK constraint that will only allow values from 0 - 100. Check out the video for how to add this constraint. CREATE TABLE dbo.[Login] ( Username VARCHAR(30) NOT NULL CONSTRAINT PK_Login_Username PRIMARY KEY (Username) , [Password] VARCHAR(30) NOT NULL , LastUpdate DATETIME2 NOT NULL CONSTRAINT DF_Login_LastUpdate DEFAULT (CURRENT_TIMESTAMP) , [Status] CHAR(10) NOT NULL CONSTRAINT CK_Login_Status CHECK ([Status] IN ('Active', 'Inactive')) , CustomerID INT CONSTRAINT FK_Login_CustomerId FOREIGN KEY (CustomerId) REFERENCES Customers (CustomerId) )

The SQL Server CURRENT_TIMESTAMP function returns the current date and time.
Date and Time Functions in SQL SERVER Part I || CURRENT_TIMESTAMP and DATEADD
This video will provide you the details of each Date and Time Data Types and Function in SQL Server 2014. I'll be walking through each and every kinds of build in function which are available in SQL Server in my next videos. Date and Time Data Types and Functions :-  CURRENT_TIMESTAMP (Transact-SQL) Returns the current database system timestamp as a datetime value without the database time zone offset. This value is derived from the operating system of the computer on which the instance of SQL Server is running. This function is the ANSI SQL equivalent to GETDATE.  Syntax CURRENT_TIMESTAMP  Arguments Takes no arguments.  Return Type Datetime  Remarks Transact-SQL statements can refer to CURRENT_TIMESTAMP anywhere they can refer to a datetime expression.CURRENT_TIMESTAMP is a nondeterministic function. Views and expressions that reference this column cannot be indexed. *********************************************************************  DATEADD (Transact-SQL) Returns a specified date with the specified number interval (signed integer) added to a specified datepart of that date.  Syntax DATEADD (datepart , number , date )  Arguments datepart Is the part of date to which an integernumber is added. The following table lists all valid datepart arguments. User-defined variable equivalents are not valid. datepart Abbreviations year yy, yyyy quarter qq, q month mm, m dayofyear dy, y day dd, d week wk, ww weekday dw, w hour hh minute mi, n second ss, s millisecond ms microsecond mcs nanosecond ns number Is an expression that can be resolved to an int that is added to a datepart of date. User-defined variables are valid. If you specify a value with a decimal fraction, the fraction is truncated and not rounded. date Is an expression that can be resolved to a time, date, smalldatetime, datetime, datetime2, or datetimeoffset value. date can be an expression, column expression, user-defined variable, or string literal. If the expression is a string literal, it must resolve to a datetime. To avoid ambiguity, use four-digit years. For information about two-digit years,  Return Types The return data type is the data type of the date argument, except for string literals. The return data type for a string literal is datetime. An error will be raised if the string literal seconds scale is more than three positions (.nnn) or contains the time zone offset part.  Return Value  datepart Argument dayofyear, day, and weekday return the same value. Each datepart and its abbreviations return the same value. If datepart is month and the date month has more days than the return month and the date day does not exist in the return month, the last day of the return month is returned. For example, September has 30 days; therefore, the two following statements return 2006-09-30 00:00:00.000: SELECT DATEADD(month, 1, '2006-08-30'); SELECT DATEADD(month, 1, '2006-08-31');  number Argument The number argument cannot exceed the range of int. In the following statements, the argument for number exceeds the range of int by 1. The following error message is returned: "Msg 8115, Level 16, State 2, Line 1.

SELECT DATEADD(year,2147483648, '2006-07-31'); SELECT DATEADD(year,-2147483649, '2006-07-31');  date Argument The date argument cannot be incremented to a value outside the range of its data type. In the following statements, the number value that is added to the date value exceeds the range of the date data type. The following error message is returned: "Msg 517, Level 16, State 1, Line 1 Adding a value to a 'datetime' column caused overflow." SELECT DATEADD(year,2147483647, '2006-07-31'); SELECT DATEADD(year,-2147483647, '2006-07-31');  Return Values for a smalldatetime date and a second or Fractional Seconds datepart The seconds part of a smalldatetime value is always 00. If date is smalldatetime, the following apply: • If datepart is second and number is between -30 and +29, no addition is performed. • If datepart is second and number is less than-30 or more than +29, addition is performed beginning at one minute. • If datepart is millisecond and number is between -30001 and +29998, no addition is performed. • If datepart is millisecond and number is less than -30001 or more than +29998, addition is performed beginning at one minute.

Difference between DateTime and DateTime2 in SQL Server
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

Working with Date Functions and Date Formatting in Excel
This video lesson is a response to two YouTube viewers who wanted my help to learn how to use Excel's Date Functions and Excel's Custom Formatting to reveal the results that they were expecting in each cell. For the first viewer: I demonstrate how to use the =DATE(Year(), Month()=9, DAY()) Function to create a date that is 9 moths after the starting date. For my second viewer, I show him how to create and apply a CUSTOM date format of yyyy-mm-dd - (Year, Month, Day) - to the DESTINATION cells when he uses Copy & Paste. This is a two step process as you will see in this video. Finally, I show you how to take advantage of the NETWORKDAYS() and WORKDAY() Functions in Excel - including an optional list of mandated Holidays in the USA.

Hibernate Tip: How to map a java.util.Date
Get more recipes like this one in my new book Hibernate Tips: More than 70 solutions to common Hibernate problems: https://goo.gl/XfywNk JPA and Hibernate offer a standard mapping for java.util.Date that stores it as a timestamp with nanoseconds. That’s OK as a default, but as always, it doesn’t fit all use cases. In this video, I want to show you how you can easily customize this mapping.
