create trigger trg_pos_machine_after_insert
after insert 
on pos_machine
for each row
begin
declare @posno varchar(4)
select @posno = posno from inserted

insert into pos_receivedate(posno,itemno)
values( @posno,"会员资料")

insert into pos_receivedate(posno,itemno)
values( @posno,"商品条码")

insert into pos_receivedate(posno,itemno)
values( @posno,"商品资料")

insert into pos_receivedate(posno,itemno)
values( @posno,"店促商品")

insert into pos_receivedate(posno,itemno)
values( @posno,"店促档期")

insert into pos_receivedate(posno,itemno)
