Types of Triggers in Oracle PL/SQL

Triggers in Oracle PL/SQL are categorized into several types based on when they are fired. The different types include:

1. BEFORE Triggers: These triggers are fired before the execution of a DML (Data Manipulation Language) statement.
2. AFTER Triggers: These triggers are fired after the execution of a DML statement.
3. INSTEAD OF Triggers: These triggers are fired in place of the triggering action for views.
4. ROW Triggers: These triggers are fired for each row affected by the triggering statement.
5. STATEMENT Triggers: These triggers are fired once for each triggering statement regardless of the number of rows affected.
6. COMPOUND Triggers: These triggers combine various types of triggers, providing more advanced functionality.
