SSIS - cast a date to use in an expression
I want to cast a date into ISO format, and use it as a string in an expression in SSIS.
This is what I type in T-SQL
select convert(varchar(8), GetDate(), 112)
and this is what I get back
My goal - is to create an archive folder based on the date. I have the File System Task part of creating a folder sorted, I can do that ... I just need to be able to Cast the date to a string, so I can use that.
Thanks in advance.
You'll need to add an expression:
RIGHT((DT_WSTR, 4) DATEPART("yyyy", GetDate()), 4) + RIGHT("0" + (DT_WSTR,2)DatePart("mm", GetDate()), 2) + RIGHT("0" + (DT_WSTR,2)DatePart("dd", GetDate()), 2)
This expression will create the result that you are after.
Old question, better-er answer, from Adrian's comment here:
Try an intermediate cast to type DT_DBDATE. Casting to WSTR gives a string in format "YYYY-MM-DD", which is easily tidied up:
Or use without the REPLACE to get the YY-MM-DD
In SSIS you would use the DT_STR or DT_WSTR cast to accomplish. A few examples are
(DT_STR, 4, 1252)YEAR(GETDATE()) + RIGHT("0" + (DT_STR, 2, 1252)MONTH(GETDATE()), 2) + RIGHT("0" + (DT_STR, 2, 1252)DAY(GETDATE()), 2)
(DT_WSTR, 4)YEAR(GETDATE()) + RIGHT("0" + (DT_WSTR, 2)MONTH(GETDATE()),2) + RIGHT("0" + (DT_WSTR, 2)DAY(GETDATE()), 2)
See the MSDN documentation for more information.
