How To Choke Only Appointment Or Fourth Dimension From Getdate() Inwards Sql Sever
The GETDATE is ane of the most pop built-in methods of Microsoft SQL Server, but dissimilar its advert suggest, it doesn't render only date, instead it returns engagement alongside fourth dimension information e.g. 2015-07-31 15:42:54.470 , quite similar to our own java.util.Date from Java world. If you lot desire only engagement similar 2015-07-31, or only fourth dimension similar 15:42:54.470 as well as hence you lot necessitate to either CAST or CONVERT output of GETDATE portion into DATE or TIME information type. From SQL Server 2008 onward, apart from DATETIME, which is used to shop both engagement as well as time, You too receive got a DATE data type to shop engagement without fourth dimension e.g. 2015-07-31, as well as a TIME information type to shop fourth dimension without whatever engagement information e.g. 15:42:54.470. Since GETDATE() portion render a DATETIME value, You receive got to usage either CAST or CONVERT method to convert a DATETIME value to DATE or TIME inwards SQL Server.
If you lot are looking for a VARCHAR value, formatted into a specific format e.g. YYYYMMDD as well as hence you lot tin too convert the DATETIME value to VARCHAR alongside a designing using CONVERT function every bit shown inwards the final instance of this article. I receive got too explained roughly divergence betwixt CAST as well as CONVERT methods as well as which ane you lot should prefer.
Remember, DATE as well as TIME types are exclusively available from Microsoft SQL Server version 2008 onward e.g. SQL Server 2012 or 2014, but you lot won't detect them into older versions e.g. SQL Server 2004. See Microsoft SQL Server 2012 T-SQL Fundamentals to larn to a greater extent than well-nigh DATE, TIME as well as DATETIME information types.
You tin too usage CONVERT() to acquire only DATE without fourth dimension from GETDATE() portion every bit shown below :
H5N1 span of worth noting points well-nigh DATE, TIME, as well as DATETIME information types inwards SQL Server:
Now, many of you lot volition last thinking whether to usage CAST or CONVERT for converting DATETIME into DATE as well as TIME information types? Well, you lot tin usage whatever of them but CAST is too SQL ANSI standard, it's meliorate to usage CAST than CONVERT. See Querying Microsoft SQL Server 2012 to larn to a greater extent than well-nigh cast as well as convert as well as dealing alongside engagement as well as fourth dimension inwards MSSQL. One of the must read books for whatever SQL Server developer.
Here is too a overnice slide well-nigh diverse engagement as well as fourth dimension information types inwards SQL Server, available from MSSQL 2008 onwards:
-- You tin too usage CAST which is measure agency to convert ane engagement type to roughly other inwards Microsoft SQL Server
-- If you lot desire Date every bit formatted String into VARCHAR variable as well as hence CONVERT portion too supports that i.e. it receive got GETDATE output as well as render VARCHAR inwards a specific engagement format. To accomplish that you lot should usage CONVERT alongside engagement format e.g. 101 to display engagement every bit MM/dd/yyyy format every bit shown inwards the next example:
Even though I suggested to prefer CAST over CONVERT at that spot are situations where you lot tin exclusively usage the CONVERT e.g. if you lot desire a formatted engagement e.g. Date inwards specific engagement format as well as hence you lot receive got to usage the CONVERT method because CAST doesn't supply engagement formatting. You tin farther read Querying Microsoft SQL Server 2012 to larn to a greater extent than well-nigh the divergence betwixt CAST as well as CONVERT operators inwards SQL Server.
Even though this majority is portion of Microsoft SQL Server instance 70-461, it's all the same a worth reading if you lot are non preparing for the examination because it teaches you lot all of import details well-nigh SQL Server. I receive got read a span of books on SQL Server as well as this is ane of the best to larn SQL Server inwards quick time.
That's all well-nigh how to shout back DATE without fourth dimension as well as TIME without engagement from GETDATE() function inwards SQL SERVER. You tin usage either CAST or CONVERT to acquire DATE as well as TIME value from DATETIME type inwards SQL Server, which obviously returns type of GETDATE function. If you lot are non converting the output of GETDATE to VARCHAR alongside specific engagement pattern, you lot should usage CAST method because it's too compliant alongside SQL measure as well as to a greater extent than probable piece of employment inwards other SQL-compliant databases similar Oracle or MySQL.

How to acquire DATE from GETDATE portion inwards SQL SERVER

You tin too usage CONVERT() to acquire only DATE without fourth dimension from GETDATE() portion every bit shown below :
SELECT CONVERT(DATE, GETDATE()) -- 2015-07-31
H5N1 span of worth noting points well-nigh DATE, TIME, as well as DATETIME information types inwards SQL Server:
- From SQL Server 2008 onwards nosotros receive got both DATE as well as TIME information types
- A DATE is only engagement without fourth dimension e.g. 2015-07-31, similar to LocalDate of Java 8
- A TIME is only fourth dimension without engagement e.g. 15:42:54:470 , similar to LocalTime of Java 8
Now, many of you lot volition last thinking whether to usage CAST or CONVERT for converting DATETIME into DATE as well as TIME information types? Well, you lot tin usage whatever of them but CAST is too SQL ANSI standard, it's meliorate to usage CAST than CONVERT.

Here is too a overnice slide well-nigh diverse engagement as well as fourth dimension information types inwards SQL Server, available from MSSQL 2008 onwards:
Getting TIME without DATE from GETDATE inwards SQL Server
SELECT CONVERT(TIME, GETDATE()) -- 15:43:20.4770000
-- You tin too usage CAST which is measure agency to convert ane engagement type to roughly other inwards Microsoft SQL Server
SELECT CAST (GETDATE() AS TIME) -- 15:47:54.6730000
-- If you lot desire Date every bit formatted String into VARCHAR variable as well as hence CONVERT portion too supports that i.e. it receive got GETDATE output as well as render VARCHAR inwards a specific engagement format. To accomplish that you lot should usage CONVERT alongside engagement format e.g. 101 to display engagement every bit MM/dd/yyyy format every bit shown inwards the next example:
SELECT CONVERT(VARCHAR(10), GETDATE(), 101) -- 07/31/2015 SELECT CONVERT(VARCHAR(10), GETDATE(), 112) -- 20150731
Even though I suggested to prefer CAST over CONVERT at that spot are situations where you lot tin exclusively usage the CONVERT e.g. if you lot desire a formatted engagement e.g. Date inwards specific engagement format as well as hence you lot receive got to usage the CONVERT method because CAST doesn't supply engagement formatting.
