About procedures and triggers

This is an article about procedures and triggers.

hello everyone! Today, we will learn about ‘procedures’ and ‘triggers’, which play important roles in database management.

Both features greatly help automate database operations and increase efficiency.

Procedure

A procedure is a function that allows a series of SQL commands to be executed as a single function in the database.

This means you can process complex queries that are used multiple times in one go.

This reduces code duplication and makes maintenance convenient.

A procedure is not executed until it is called, either by an explicit request from the user or by another trigger or procedure.

Additionally, you can receive parameters within a procedure and perform operations dynamically.

Trigger

A trigger is a procedure that is automatically executed in the database when a specific event (data insertion, modification, deletion, etc.) occurs.

This allows you to ensure data consistency, automatically check that certain conditions are met, or process complex business rules within the database.

Triggers are automatically executed when certain conditions are met without any explicit call from the user.

This maintains the integrity of the database and enables efficient data management.

summary

If you understand the characteristics of procedures and triggers and utilize them well, you can perform database operations more efficiently.

This reduces the complexity of database management and increases the accuracy and stability of operations.
