PostgreSQL supports row-level and statement-level triggers.Datagrip license Any exercise of rights under this license by you or your sub-licensees is subject to the following conditions: 1.A trigger is a function invoked automatically when an INSERT, UPDATE, DELETE, or TRUNCATE occurs on a table.PostgreSQL requires you to define a user-defined function as the action of the trigger, while the SQL standard allows you to use any SQL commands.PostgreSQL allows you to define the statement-level trigger on views.PostgreSQL fires trigger for the TRUNCATE event.PostgreSQL triggers vs SQL standard triggersĮven though PostgreSQL implements SQL standard, triggers in PostgreSQL has some specific features: The main drawback of using a trigger is that you must know the trigger exists and understand its logic to figure out the effects when data changes. For example, when a new row is added into the customer table, other rows must be also created in tables of banks and credits. For example, if you want to keep the history of data without requiring the application to have logic to check for every event such as INSERT or UDPATE.Īlso, you can use triggers to maintain complex data integrity rules which cannot implement elsewhere except at the database level. Triggers are useful in case the database is accessed by various applications, and you want to keep the cross-functionality within the database that runs automatically whenever the data of the table is modified. In case the trigger is invoked after the event, all changes are available to the trigger. If the trigger is invoked before an event, it can skip the operation for the current row or even change the row being updated or inserted. You can specify whether the trigger is invoked before or after an event. The differences between the two kinds are how many times the trigger is invoked and at what time.įor example, if you issue an UPDATE statement that modifies 20 rows, the row-level trigger will be invoked 20 times, while the statement-level trigger will be invoked 1 time. PostgreSQL provides two main types of triggers: The difference between a trigger and a user-defined function is that a trigger is automatically invoked when a triggering event occurs. To create a new trigger, you define a trigger function first, and then bind this trigger function to a table. An event could be any of the following: INSERT, UPDATE, DELETE or TRUNCATE.Ī trigger is a special user-defined function associated with a table. What are PostgreSQL triggersĪ PostgreSQL trigger is a function invoked automatically whenever an event associated with a table occurs. Summary: in this tutorial, you will learn about PostgreSQL triggers, why you should use the triggers, and when to use them.
