Triggers is a special type of stored procedure that is not called directly by user. When the trigger is created, it is defined to fire when a specific type of data modification is made against a specific table or column. Consider improving both the format and content of this answer.

Both are database objects containing blocks lof code that can be used for implementing business logic The differences are: 1 Triggers fire automatically but they need events for that. Karthick Kumar 2, 1 1 gold badge 15 15 silver badges 29 29 bronze badges.
Difference Between a Stored Procedure and a Trigger We can define a trigger as a database object just like a stored procedure, or we can say it is a special kind of stored procedure which fires when an event occurs in a database.
Triggers are fired implicitly while stored procedures are fired explicitly. Code Code 4 4 silver badges 8 8 bronze badges. Sign up or log in Sign up using Google. Sign up using Facebook. Sign up using Email and Password. Post as a guest Name. Email Required, but never shown.
The Overflow Blog. Does ES6 make JavaScript frameworks obsolete? Triggers are similar to stored procedures but differ in the way that they are invoked. Support for triggers in MySQL is only included beginning with release 5. All triggers defined on MySQL are row triggers, which means that the action defined for the triggers is executed for each row affected by the triggering statement. Error handling during trigger execution for transactional tables ensures that either both the triggering statement and trigger action is completed successfully or neither the trigger statement nor the trigger action is executed, that is all changes made are rollback on failure.
For non-transactional tables, all changes made prior to the point of error remains in effect. Oracle allows multiple triggers with the same trigger timing and trigger event to be defined on a table; however, these triggers are not guaranteed to execute in any specific order. Triggers can be defined as row triggers or statement triggers.
Statement triggers are fired once for each triggering statement regardless of the number of rows in a table affected by the triggering statement. The execution model for Oracle triggers is transactional.
All actions performed as a result of the triggering statement, including the actions performed by fired triggers, must all succeed; otherwise, they are rolled back.
Stored procedures provide a powerful way to code application logic that can be stored on the server. MySQL and Oracle both use stored procedures and functions. Stored functions are similar to procedures, except that a function returns a value to the environment in which it is called. In MySQL, stored procedures and functions are collectively called routines. Let us discuss some more differences between Trigger and Procedure with the help of a comparison chart shown below. Basis for Comparison Triggers Procedures Basic They are automatically executed on occurrence of specified event.
They can be executed whenever required. Calling Triggers can't be called inside a procedure. But, you can call a procedure inside a trigger.
Parameter We can not pass parameters to triggers. We can pass parameters to procedures.
