I am having horrible issues with this Update query (TSQL MS SQL 2008r2)
------ This should update all the Frozen fields where Frozen = 1 and FrozenDate <= Today minus 5 -------------
DECLARE @MyDate DATETIME
SELECT @MyDate = DateAdd(DD, -5, GETDATE())
SET Frozen = 0
Where FrozenDate <= @MyDate
However, I am receiving this error:
Msg 512, Level 16, State 1, Procedure TR_FrozenDate, Line 8
Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.
The statement has been terminated.
I started with a subselect in the WHERE Clause, but altered the script to what you see above.
While I may SELECT all the rows which fit this description, I can not update the dbo.Frozen field.
Any help would be great appreciated.
