Question

I want to select some data from one table if a date from another table is at least 6 months before today.
I tried going off of something like this:
Select records from SQL Server if greater than 6 months
but I get the error: Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.
Here is my way of approching this:

SELECT FCIF, [Date], [Desc]
FROM tblFCIF
WHERE tblFCIF.FCIF =
(SELECT FCIFSignOff.FCIF
FROM FCIFSignOff
WHERE ID='12'
AND (DateDiff(month,SignOffDate,GetDate()) > 0) )

So this code withouth the last line selects everything with the ID, 12. I just need to get everything that is from 6+ months ago.

DATEDIFF(datepart,startdate,enddate)

when ‘month’ is in daypart it returns the difference in months.

Answer 1

Instead of your DateDiff line, use:

AND (DateAdd(MM, -6, GetDate()) > SignOffDate)
