Question

In a stored procedure I have an IF condition to check whether the orgID exists in the result of the query to set the flag. What would be the correct syntax??

create procedure temp
(@TEMpID char(6)
)
declare @orgID char(3),flag char(1)
SET flag ='N'

BEGIN
set
 @OrgID =(selecte orgID from table1)
IF @OrgID exists in ( select distinct(OrgID) from table2)
set flag = 'Y'

END

Begin 
select p1, p2, p3, flag
from table3

END 

Answer 1

Something like this:

IF exists ( select 1 from table2 where OrgID=@OrgID)
   set flag = 'Y'

Note: I think you have too many begin/end blocks.

You can write your proc as:

create procedure temp
( 
   @TEMpID char(6)
)
as
BEGIN
   --whole body here
END
