Can be solved using DECLARE and derived column

DECLARE @OrdNum varchar(5)
DECLARE @Empid int
SET @OrdNum='XZ1'
SET @Empid=200
SELECT * FROM (SELECT OrdNum,Empid,Mgrid,MgrLevel FROM #Orders
WHERE OrdNum=@OrdNum AND Empid=@Empid
) AS A

Heh... funny enough, that works for the data given. The given data isn't actually hierarchical data (yet).

You don't need the outer SELECT, though.

RBAR is pronounced ree-bar and is a Modenism for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
Stop thinking about what you want to do to a row... think, instead, of what you want to do to a column.
If you think its expensive to hire a professional to do the job, wait until you hire an amateur. -- Red Adair

NP. The following will do the exact same thing as your query. All I did was remove the outer SELECT.


DECLARE @OrdNum varchar(5)
DECLARE @Empid int
SET @OrdNum='XZ1'
SET @Empid=200
SELECT OrdNum,Empid,Mgrid,MgrLevel FROM #Orders
WHERE OrdNum=@OrdNum AND Empid=@Empid
