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.
Although they tell us that they want it real bad, our primary goal is to ensure that we dont actually give it to them that way.
Although change is inevitable, change for the better is usually not.
Just because you can do something in PowerShell, doesnt mean you should. Wink
