Re: Enforce business rule with before insert trigger?

[Bob Field]

Hello all,

I'm new here and I think this is the appropriate place to ask this:

I have a pair of tables, the first of which store a unique sequence number for each transaction, and the second that stores the detail lines of the transaction. I will be adding all the detail lines to the second table via a single INSERT operation and wish to have a trigger that fires upon completion of inserting these rows in order to calculate the total amount of these detail lines and be able to roll back the entire operation if the total does not meet my criteria.

Any insights here?

Thanks in advance,

Bob.
