Re: translate this Sql Server Query into DB2 Sql for AS/400 ?

You are very well correct, its a trigger which will generate LEVEL AND
HIERARCHY of given data, and I want to do the same thing in DB2 for AS/400.

The trigger is from Sql Server, its:

CREATE TRIGGER trg_employees_i_calchierarchy ON Employees FOR INSERT
AS
DECLARE @numrows AS int
SET @numrows = @@rowcount
IF @numrows > 1
BEGIN
  RAISERROR('Only single row inserts are supported!', 16, 1)
  ROLLBACK TRAN
END
ELSE
IF @numrows = 1
BEGIN
  UPDATE E
  SET lvl =
        CASE
          WHEN E.mgrid IS NULL THEN 0
          ELSE M.lvl + 1
        END
  FROM Employees AS E JOIN inserted AS I
    ON I.empid = E.empid
    LEFT OUTER JOIN Employees AS M
    ON E.mgrid = M.empid
END


Best Regards,
