Date and Time Conversions Using SQL Server

Problem

There are many instances when dates and times don't show up at your doorstep in the format you'd like it to be, nor does the output of a query fit the needs of the people viewing it. One option is to format the data in the application itself. Another option is to use the built-in functions SQL Server provides to format the date string for you.

Solution

SQL Server provides a number of options you can use to format a date/time string. One of the first considerations is the actual date/time needed. The most common is the current date/time using getdate(). This provides the current date and time according to the server providing the date and time. If a universal date/time is needed, then getutcdate() should be used. To change the format of the date, you convert the requested date to a string and specify the format number corresponding to the format needed. Below is a list of formats and an example of the output:

DATE FORMATS
Format # Query (current date: 12/30/2006) Sample
1 select convert(varchar, getdate(), 1) 12/30/06
2 select convert(varchar, getdate(), 2) 06.12.30
3 select convert(varchar, getdate(), 3) 30/12/06
4 select convert(varchar, getdate(), 4) 30.12.06
5 select convert(varchar, getdate(), 5) 30-12-06
6 select convert(varchar, getdate(), 6) 30 Dec 06
7 select convert(varchar, getdate(), 7) Dec 30, 06
10 select convert(varchar, getdate(), 10) 12-30-06
11 select convert(varchar, getdate(), 11) 06/12/30
101 select convert(varchar, getdate(), 101) 12/30/2006
102 select convert(varchar, getdate(), 102) 2006.12.30
103 select convert(varchar, getdate(), 103) 30/12/2006
104 select convert(varchar, getdate(), 104) 30.12.2006
105 select convert(varchar, getdate(), 105) 30-12-2006
106 select convert(varchar, getdate(), 106) 30 Dec 2006
107 select convert(varchar, getdate(), 107) Dec 30, 2006
110 select convert(varchar, getdate(), 110) 12-30-2006
111 select convert(varchar, getdate(), 111) 2006/12/30
TIME FORMATS
8 or 108 select convert(varchar, getdate(), 8) 00:38:54
9 or 109 select convert(varchar, getdate(), 9) Dec 30 2006 12:38:54:840AM
14 or 114 select convert(varchar, getdate(), 14) 00:38:54:840

You can also format the date or time without dividing characters, as well as concatenate the date and time string:

Sample statement Output
select replace(convert(varchar, getdate(),101),'/','') 12302006
select replace(convert(varchar, getdate(),101),'/','') + replace(convert(varchar, getdate(),108),':','') 12302006004426
Next Steps
  • The formats listed above are not inclusive of all formats provided. Experiment with the different format numbers to see what others are available
  • These formats can be used for all date/time functions, as well as data being served to clients, so experiment with these data format conversions to see if they can provide data more efficiently

I just had a request from our Oracle team to see if I could supply them with dates in a MMDDYYYYHHMMSS format. Came here and found what I need in all of about 30 seconds. Thanks.

Select the particular year,month, day,pls do following query

 ---------------------------------------------------------------------------------------

select * from barrowBooks where year(barrow_date)='2008' and month(barrow_date)='11' and day(barrow_date)='12'  order by barrow_date desc

 

convert the date and time  using this query

----------------------------------------------------------------

select convert(char(11),getdate(),108) -->Result of time  11:18:18

select convert(char(10),getdate(),101) -->Result of Date  11/06/2008

Actually, I was simply complimenting the "tip" as it provided exactly what I needed for ANY date:

 select replace(convert(varchar, getdate(),101),'/','') + replace(convert(varchar, getdate(),108),':','')

This converts any MSSQL datetime to MMDDYYYYHHMMSS - exactly what the Oracle folks wanted!

 

Thanks anyway :-)

It's very helpful info thanks for help!!!!!


Wednesday, May 16, 2012 - 7:42:46 AM - Tessa Read The Tip

I would like to see the complete date and time a DD-MM-YYYY HH:MM:SS

I use: convert(varchar,getdate(),105) + convert(varchar,getdate(),108)

I get: 16-05-201213:42:18

 

How would I get the extra space between the Date and Time to get 16-05-2012 13:42:18

Tessa,

Would this work for you?

convert(varchar,getdate(),105) + ' ' + convert(varchar,getdate(),108)

Is there any reason you would not use this format:

9 or 109 select convert(varchar, getdate(), 9) Dec 30 2006 12:38:54:840AM

Can any one help me out this

satheeshkumar,

Have you checked out Tim Ford's tip - http://www.mssqltips.com/sqlservertip/1712/sql-server-function-to-convert-integer-date-to-datetime-format/?

I believe he has a function to take care of the date logic, but I think you will have to modify it to include the time logic you need.

HTH.

Thank you,
Jeremy Kadlec
