This article shares with you about the advantages of the mysql storage process. The editor thought it was very practical, so I shared it with you as a reference. Let's follow the editor and have a look.

However, in the actual operation of the database, there is often a complete operation that requires multiple SQL statements to deal with multiple tables.

For example, in order to confirm whether a student can graduate, you need to query the student file table, score table, and comprehensive table at the same time, and you need to use multiple SQL statements to complete this processing requirement for several data tables. Stored procedures can effectively complete this database operation.

Stored procedure is an important function of database storage, but MySQL did not support stored procedure before 5. 0, which greatly reduced the application of MySQL. Fortunately, MySQL 5.0 has finally begun to support stored procedures, which can not only greatly improve the processing speed of the database, but also improve the flexibility of database programming.

A stored procedure is a collection of SQL statements that perform specific functions. The purpose of using stored procedures is to pre-write common or complex work in SQL statements and store them with a specified name. This process is compiled and optimized and stored in the database server, so it is called a stored procedure. When you need the database to provide the same service as the defined stored procedure in the future, you only need to call "CALL stored procedure name" to do it automatically.

The SQL statements commonly used to manipulate the database need to be compiled and then executed. Stored procedures execute SQL statements in a different way.

A stored procedure is a programmable function that is created and saved in the database and is generally composed of SQL statements and some special control structures. Stored procedures are especially appropriate when you want to perform the same specific functions on different applications or platforms.

Stored procedures usually have the following advantages:

1) encapsulation

After a stored procedure is created, it can be called many times in the program without having to rewrite the SQL statement of the stored procedure, and database professionals can modify the stored procedure at any time without affecting the application source code that calls it.

2) it can enhance the function and flexibility of SQL statement

The stored procedure can be written with flow control statements, which has strong flexibility and can complete complex judgments and more complex operations.

3) reduce network traffic

Because the stored procedure runs on the server side and executes quickly, when the stored procedure is called on the client computer, only the calling statement is transmitted in the network, thus reducing the network load.

4) High performance

After the stored procedure is executed once, the resulting binary code resides in the buffer, and in future calls, only the binary code needs to be executed from the buffer, thus improving the efficiency and performance of the system.

5) improve database security and data integrity

All database operations can be completed by using stored procedures, and the access to database information can be controlled programmatically.

Thank you for reading! What are the advantages of mysql storage process to share here, I hope the above content can be of some help to you, so that you can learn more knowledge. If you think the article is good, you can share it and let more people see it.
