SQL - using a variable for an IN clause

Question

I wish to do something like the following:

declare @FrameNumber nvarchar(20)
set @FrameNumber = \'(p1, p2)\'

select from myTable where c1 in @FrameNumber
         


        

Answer 1

DECLARE @FrameNumbers TABLE (code NVARCHAR(20) PRIMARY KEY)

INSERT
INTO   @framenumbers
VALUES ('p1')

INSERT
INTO   @framenumbers
VALUES ('p2')

SELECT  *
FROM    mytable
WHERE   c1 IN
        (
        SELECT  code
        FROM    @framenumbers
        )
