Question

Accepted Answer

Triggers are database objects that execute automatically in response to certain events. Mutating trigger problem occurs when a trigger tries to read or modify a table that is already being modified by the same transaction.

Triggers can be used to enforce business rules, audit changes, and maintain referential integrity.
They can be used to automatically update a table when a related table is updated.
Mutating trigger problem can be solved by using compound triggers, which allow the trigger to be executed in multiple stages.
Another solution is to use autonomous transactions, which allow the trigger to read and modify the table without interfering with the main transaction.
