SQL triggers are database objects that are associated with a table and are automatically executed in response to certain events

The triggers can be INSERT, UPDATE, or DELETE operations on the table.

Triggers are used to automate certain actions in response to changes in a database table.

Example:Update total amount in orders table after order_details is inserted, updated, or deleted.

Triggers are defined using the CREATE TRIGGER statement, and are associated with a specific table and a specific event.

Triggers can be used to enforce complex business rules that cannot be enforced using constraints or other database objects.

Triggers can be nested, meaning that a trigger can itself execute another trigger in response to a triggering event.

Triggers can cause performance issues if not properly designed and optimized
