Creating A Trigger

2
Hallo,
I am new on this forum but I have an urgent problem. How can I

1. Create a trigger which has the following characteristics:
• It should be named reorder.
• It should fire after an update of the qty column on the stock table, if the new
value of qty is <= 5.
• New should be referenced as n.
• The triggered action should insert the values n.itemno and current timestamp
into the reorder table,
whereby when an inventory item in the STOCK table falls below a quantity of 6, the REORDER table will have a row inserted.

Any kind of help is very much appreciated.

hi jkag,

Check out the Trigger i have developed in sqlserver 2000.

sample tables used:
create table stock
(
itemid int identity(1,1) primary key,
prdname varchar(100),
qty int,
)

create table reorder
(
reoid int identity(1,1) primary key,
itemid int,
prdname varchar(100),
qty int,
currdate timestamp
)

create Trigger ReorderTrigg
on stock
for update
as
begin
insert into reorder(itemid,prdname,qty) select itemid,prdname,qty from stock where qty<=5
end
go

Go through the trigger and do let me know if it has solved ur query. If not also, pm me your problem. I shall try it. Gud Luck!

cheers,
jai
