Hi, I have a query where I need to use the IN variable. Is there a way to do it without using dynamic query? For example,
select *
from table
where data IN ('A', 'B')

works fine. Is there a way for me to pass a variable to the IN clause instead of the static 'A', 'B'.

you can see



DECLARE @VarList varchar(1000)

SET @VarList = 'A,B'

SELECT *
FROM table
WHERE ',' + @VarList + ',' LIKE '%,' + data + ',%'

sorry didnt understand how this will work.

check below code


DECLARE @VarList varchar(1000)

declare @t table
(
id int identity(1,1),
chr char(1)
)
insert @t (chr)
values ('A'),('C'),('D'),('F')

SET @VarList = 'A,F'

SELECT *
FROM @t
WHERE chr IN(select @VarList)

If your table is large, use function for better performance.
