MySQL Procedure Purpose Explained

MySQL stored procedure is a predefined database operation that accepts parameters, executes specific logic, and returns results. Its purpose can be summarized as follows:

1. Improving performance: Stored procedures can be executed on the database server, reducing the cost of network transmission and improving the efficiency of queries and operations.
2. Reusing code: Stored procedures can be called by multiple applications or queries, preventing the need to repeatedly write the same code.
3. Maintaining data integrity: Stored procedures can enforce complex data validation and constraints, ensuring the integrity and consistency of data.
4. Simplify security management: By using stored procedures, users’ direct access to the database can be restricted, allowing them to only perform specific operations through stored procedures, thus streamlining security management.
5. Support for transaction processing: Stored procedures can contain multiple SQL statements, enabling the use of transactions to ensure the atomicity of multiple operations and guarantee data consistency.

In conclusion, the function of MySQL stored procedures is to provide a way to execute pre-defined operations on the database server in order to improve performance, reuse code, maintain data integrity, simplify security management, and support transaction processing.
