Two triggers on one table sql server
I have two triggers on one of the tables in my database. One is for insert trigger and the other 开发者_高级运维is an after update trigger. The insert trigger will update the table with values. My question is this; Is it possible that that the update trigger is firing at the same time that the insert is doing its job?
A FOR INSERT
trigger will fire only on INSERT
statements. A FOR UPDATE
trigger will fire only on UPDATE
statements. Of course, if your insert trigger executes any UPDATE
statements then it will fire the update trigger, and vice versa.
Your UPDATE
trigger won't fire for an INSERT
statement (excepting the update-within-trigger case above), but of course you still have to design for concurrency, since it's possible for two different users to be running two different operations at the same time - one INSERT
and one UPDATE
.
If your insert trigger does an update to the table, the update trigger will be called. If a trigger triggers another trigger, it's called a "recursive trigger".
Recursive triggers can be disabled for an entire server:
sp_configure 'nested_triggers', 0
go
reconfigure
Or for one database:
alter database yourdb set recursive_triggers off
