What are the advantages and disadvantages of using MySQL stored procedures?

There are many advantages and disadvantages of using MySQL stored procedures, as shown below −

Advantages of MySQL stored procedures

Using MySQL stored procedures The advantages are as follows −

• Improving application performance − We know that after creating a stored procedure, it will be compiled and stored in the database. But MySQL implements stored procedures slightly differently, which helps improve the performance of your application. MySQL stored procedures are compiled on demand. After compiling the stored procedure, MySQL places it in the cache. And MySQL maintains its own cache of stored procedures for each individual connection. If the application uses the stored procedure multiple times within a single connection, the compiled version is used; otherwise, the stored procedure acts like a query.
• Fast − MySQL stored procedures are fast because the MySQL server takes advantage of caching. Another reason for its speed is that it reduces network traffic. Suppose we have a recurring task that requires checks, loops, multiple statements, and no user interaction, and can be accomplished with a single call to a procedure stored on the server.
• Portable − MySQL stored procedures are portable because when we write a stored procedure in SQL, we know that it will run on every platform that MySQL runs on, regardless of You need to install additional runtime environment packages or set program execution permissions in the operating system.
• Reusable and transparent − Stored procedures expose the database interface to all applications so that developers do not have to develop functions that are already supported in stored procedures. Therefore, we can say that MySQL stored procedures are reusable and transparent.
• Security − MySQL stored procedures are secure because the database administrator can grant appropriate permissions to applications that access stored procedures in the database without granting anything on the underlying database tables. permissions.

Disadvantages of MySQL stored procedures

The disadvantages of using MySQL stored procedures are as follows −

• Increased memory usage − If you use many Stored procedures, memory usage per connection using these stored procedures will increase significantly.
• Limitations on complex business logic − In fact, the structure of stored procedures is not suitable for developing complex and flexible business logic.
• Debugging Difficulty − Debugging stored procedures is difficult. Only a few database management systems allow you to debug stored procedures. Unfortunately, MySQL does not provide the ability to debug stored procedures.
• Difficulties in Maintenance − Developing and maintaining stored procedures is not easy. Developing and maintaining stored procedures often requires a specialized skill set that not all application developers possess. This can cause problems during application development and maintenance phases.
