Using Trigger in SQL Server 2005

    Hi all,

    I am using trigger in TABLE A for update TABLE B with below code

    CREATE TRIGGER [dbo].[UpdtMasterFG]

    ON [dbo].[RateLog]

    FOR Update

    As

    UPDATE FinishGoods SET

    dbo.FinishGoods.CurrentQty1 =(SELECT SUM(dbo.RateLog.Qty1) FROM dbo.RateLog WHERE

    dbo.RateLog.StyleNo = dbo.FinishGoods.StyleNo AND dbo.RateLog.ColorID = dbo.FinishGoods.ColorID AND dbo.RateLog.SizeID = dbo.FinishGoods.fldSize)

    Its working fine but problem is , it is updating all record (7000 record) of table "FinishGoods". i want to update only those record which i update in "RateLog" Table.

    i heard about inserted table but don't know how to use it.

    Any help would be appreciable.

    Thanks & regards,

    Mohammad Yusuf

    The inserted table has the same structure as the table the trigger is on, but only has the rows have been changed. Hence you would probably use it in place of RateLog in the trigger.

    Ya those exemples are harder to fin in the documentation (not in create trigger, but burried deep in a link).
