A stored procedure in MySQL is a set of precompiled SQL statements that are stored in the database and can be executed multiple times with different parameters. It is used to encapsulate a series of SQL statements to perform a specific task or operation. Stored procedures provide several benefits, such as improved performance, code reusability, and enhanced security.
Advantages of Stored Procedures
Improved Performance: Stored procedures are precompiled, reducing parsing and optimizing execution time.
Code Reusability: Procedures can be called from different parts of the application, promoting modular programming.
Security: Procedures allow better control over data access, reducing direct SQL injection vulnerabilities.
Maintainability: Centralized logic in stored procedures simplifies maintenance and updates.
How to show or list stored procedures in MySQL?
When we have several procedures in the MySQL server, it is very important to list all procedures. It is because sometimes the procedure names are the same in many databases. In that case, this query is very useful. We can list all procedure stored on the current MySQL server as follows:
SHOW PROCEDURE STATUS [LIKE 'pattern' | WHERE search_condition]
