Where..IN..

Hello all
I have this query
DECLARE @a nvarchar(50)
SET @a = '1,3'

select * 
from tableName 
where CAST(ColumnId as nvarchar(50)) in (@a)

Open in new window

which doesn't work.
i would like it to work like the following query
select * 
from tableName 
where ColumnId in (1,3)

Open in new window
