This is for an inventory table. When the inventory Field is changed or a new record inserted, I would like to set another field to 1.

This is what I have and it throws a lot of errors.I know next to nothing about Transact-SQL and could use some assistance.

CREATE TRIGGER upd_flag on (MyTable)
For UPDATE
AS
if update (Inventory)
Update MyTable SET tbl_Flag = 1
Where Inventory (select inventory FROM inserted)

Any help would be appreciated.
Thanks
Bill

CREATE TRIGGER upd_flag on (MyTable)
For UPDATE
AS
if update (Inventory)
Update MyTable
SET tbl_Flag = 1
from inserted
Where MyTable.Inventory = insertd.inventory

or you could

if update (Inventory)
Update MyTable SET tbl_Flag = 1
Where Inventory in (select inventory FROM inserted)

==========================================
Cursors are useful if you don't know sql.
DTS can be used in a similar way.
