For most triggers,you can avoid mutating table errors by using statement triggers with new and old values.

Question

Quizplus · Accepted Answer

Mutating table errors occur because a row-level trigger is trying to read or modify a table that is already being modified by the statement that fired the trigger. Using statement-level triggers instead does not inherently solve the problem, as these triggers do not have access to row-specific "new" or "old" values, which are necessary for many operations that could lead to mutating table errors. The solution often involves redesigning the logic, possibly using a combination of triggers, temporary tables, or changing the timing of the trigger.
