Converting yyyy/mm/dd hh:mm:ss

  • How do you make this:

    yyyy/mm/dd hh:mm:ss

    Look like this:

    mm/dd/yyyy hh:mm --hh:mm needs to be in military time

  • This has pretty much every format imaginable for datetimes. http://msdn.microsoft.com/en-us/library/ms187928.aspx

  • Are these date/time values stored as character strings or as date/time values in a columns defined datetime or datetime2?

    I would be seriously concerned about performance if this is used. This is living proof that formatting should not be handled by sql server. Push formatting to the front end whenever possible.

    There is only one display format in ANSI SQL; the ISO-8601 version with dashes "yyyy-mm-dd HH:MM:SS.sssssss". Please notice I said display format.

    SQL is an abstract model of data. We do not care how it is kept internally because in an tiered architecture will pass it to a presentation layer that will turn the internal format into a local display of some kind. This is how client/server works.

    Your mindset is still back in monolithic code where there are no tiers. You are still programming in 1950's COBOL where the data was kept in strings and your programs worked with it that way.

    The CONVERT string function is a left-over from the early days of Sybase when we actually tried to write monolithic T-SQL. You need to catch up with the last 35 years of programming

    Um, the question was:

    How do you make this:

    yyyy/mm/dd hh:mm:ss

    Look like this:

    mm/dd/yyyy hh:mm --hh:mm

    My reply included a solution. I could have provided several solutions but chose the one with the least code. I am sorry that the CONVERT function is such a source of anxiety for you.

  • This would make the trick. But as noted by others, formatting should be done on the front end.

    DECLARE@Datedatetime

    SET @Date = '20120523 18:03:12.523'

    SELECT CONVERT( char(10), @Date, 101) + ' ' + CONVERT( char(5), @Date, 8)

  • There's a whole series of date manipulation examples on Robyn Page's site: http://www.simple-talk.com/sql/learn-sql-server/robyn-pages-sql-server-datetime-workbench/

    A little out of date now, but still useful.

    You are getting a lot of responses, but the biggest problem is that we are shooting in the dark as we have no idea how, where, or why you are trying to accomplish this in SQL. How about giving us some more information so we can offer better advice.
