Martin,
In SQL Server 7/2000, you can build a dynamic SQL statement and use the SP_EXECUTE stored produre. Ex.

declare @cSQL nvarchar(4000)

set @cSQL = N'update mytable set W' + convert(nvarchar(2),datepart(wk,getdate()))	+
   N' = somevalue where mytable.pk = somepk'
exec sp_executesql @cSQL

HTH.
