The primary purpose of using triggers in PL/SQL is to automatically execute code when certain events occur in the database. Triggers are special types of stored procedures that are defined to execute automatically in response to certain events in the database. They can be associated with tables, views, schemas, or the database itself, and they can be invoked either before or after the event. This allows for complex business rules to be encapsulated in the database, ensuring data integrity and consistency.
