Hi, I am trying to create an update trigger and everything is correct except how do I pass variables into a stored procedure that I am calling within a trigger. My example is below:

CREATE TRIGGER master_update_trigger
ON dbo.ksu_master_term_table
FOR UPDATE

AS

if update(hall)
begin
      if exists (select * from restv.dbo.restv_table, inserted where restv.dbo.restv_table.
      client_id=inserted.stud_id and restv.dbo.restv_table.term_code=inserted.term_code
      and  restv.dbo.restv_table.active ="Y")
      begin
      
            update restv.dbo.restv_table set restv.dbo.restv_table.active = "N",
            restv.dbo.restv_table.done = "N",restv.dbo.restv_table.hall=inserted.hall,
            restv.dbo.restv_table.room = inserted.room, restv.dbo.restv_table.local_phone=inserted.
            local_phone From inserted where restv.dbo.restv_table.client_id=inserted.stud_id and
            restv.dbo.restv_table.term_code=inserted.term_code

--------------------------->  exec restv_insert_sp

--------------------------->insert into restv.dbo.restv_table (client_id,hall,room,first_name,last_name,term_code,
            converter_cost,converter_qty,coax_cable_qty,coax_cable_cost,hbo_cost,showtime_cost,
            total_cost,previous_term_code,done,active,date_time_stamp,local_phone,billed,order_num)
            values ("deleted.client_id","deleted.hall","deleted.room","deleted.first_name","deleted.
                  last_name","deleted.term_code","deleted.converter_cost",CONVERT(tinyint,"deleted.converter_qty"),
            CONVERT(tinyint,"deleted.coax_cable_qty"),CONVERT(smallmoney,"deleted.coax_cable_cost"),
            CONVERT(smallmoney,"deleted.hbo_cost"),CONVERT(smallmoney,"deleted.showtime_cost"),
            CONVERT(money,"deleted.total_cost"),"deleted.previous_term_code","deleted.done","deleted.active",
            "getdate()","deleted.local_phone","deleted.billed",CONVERT(int,"deleted.order_num"))
            From deleted where restv.dbo.restv_table.client_id=inserted.stud_id and
            restv.dbo.restv_table.term_code=inserted.term_code
      end      
end


All I am trying to do is to create an update trigger that will update a record in another datebase and will
insert the old record before the update also into another datebase. Can you tell mw what is wrong with my syntax where I am trying to insert the old record after the stored procedure

To call a stored proc from inside a trigger all you have to do is pass the right parameters to the stored proc. So if the stored proc is expecting two parameters, just call the stored proc with the right parameters inside paranthesis
exec stored_proc(parameterA, parameterB)

That should work.

By the way I do not know of any before update triggers in MS SQL Server..maybe you wanna check whether that is allowed. However I do not see any before or update clause in your code. maybe you're doing so by the stored proc?
