how to format getdate into YYYYMMDDHHmmSS

Question

In SQL Server how do I format getdate() output into YYYYMMDDHHmmSS where HH is 24 hour format?

I\'ve got the YYYYMMDD

Answer 1

converting datetime that way requires more than one call to convert. Best use for this is in a function that returns a varchar.

select CONVERT(varchar,GETDATE(),112) --YYYYMMDD
select CONVERT(varchar,GETDATE(),108) --HH:MM:SS

Put them together like so inside the function

DECLARE @result as varchar(20)
set @result = CONVERT(varchar,GETDATE(),112) + ' ' + CONVERT(varchar,GETDATE(),108)
print @result

20131220 13:15:50

As Thinhbk posted you can use select CONVERT(varchar,getdate(),20) or select CONVERT(varchar,getdate(),120) to get quite close to what you want.
