Question

For each row in the table SalesRep_Info, i have a column ManagerID. ManagerID is the primary key of the same table having the ManagerID saved for each Sales Rep. So i need to get the FirstName of the Manager as a new column. I am wondering if this is the right way of doing it in sql server 2005 by declaring and setting?!!

Thank you in advance!

declare @RepID int

set @RepID = (Select Manager from SalesRep_Info)

Select *, (Select FirstName from SalesRep_Info where RepID=@RepID) as ManagerFname from SalesRep_Info

You want a join:

SELECT
    a.*,
    b.FirstName AS ManagerFirstName
FROM
    SalesRep_Info a
    LEFT JOIN SalesRep_Info b ON a.ManagerID = b.RepID
