Hi does anyone know how to create a query in SQL 2000 or 2005 to get the year and week number together for a date i.e. the 01/01/2008 would be 200801. I know how to get them seperately using datepart but i need them joined together.
Any help would be much appreciated.

select ltrim(year('01/01/2008')) + right('0' + ltrim(datepart(week, '01/01/2008')), 2)

Solutions are easy. Understanding the problem, now, that's the hard part.

If you want a whole bunch of them, you should consider making use of this date function...

http://www.sqlteam.com/forums/topic.asp?TOPIC_ID=61519

select DATE, ISO_YEAR_WEEK_NO from dbo.F_TABLE_DATE('1/1/2008', '1/1/2009')

Better still, use that function to create a permanent, fully-indexed table, and then use that.

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.
