Hi,
I have two tables namely account and invoice.
I want to update one field in account table when there is A NEW RECORD inserted in invoice table. I want to use only triggers nothing else.
Thanks

If this is your most optimal way, I cannot tell, but if you insist on using a trigger...

Create trigger utr_I_Invoice on dbo.invoice

for insert

as

update A

set yourcol=yourcol + whatever

from dbo.account A

inner join inserted I

on A.account_id = I.Invoice_Account_Id

Thanks a lot 🙂

I got it; could you please tell me how to use for loop if I need to pick up one of the different lookup (drop-down) values.

for example, I want to update the flag to true in account table. but before updating the value I must compare one field (say id) with the one in another table but is in lookup format means you can select one value from the drop down.

Thanks

euhm ... there is no "dropdown" in sqlserver.

The only thing you have is a set of rows (from a table, view, ..)

just add an extra
