This article will explain in detail what is the role of mysql using the storage process, Xiaobian thinks it is quite practical, so share it with you as a reference, I hope you can gain something after reading this article.

The role of mysql using stored procedures: 1, enhance the functionality and flexibility of SQL statements;2, reduce network traffic, thereby reducing network load;3, improve database access efficiency;4, improve database security and data integrity;5, make data independent, achieve decoupling effect.

A stored procedure is a collection of SQL statements designed to perform a specific function. The purpose of using stored procedures is to write common or complex work in advance with SQL statements and store it with a specified name. This procedure is compiled and optimized to be stored in the database server, so it is called a stored procedure. When the database is later required to provide the same service as the defined stored procedure, simply call "CALL stored procedure name" to automatically complete it.

SQL statements for commonly used operation databases need to be compiled first and then executed. Stored procedures take a different approach to executing SQL statements.

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

MySQL did not support stored procedures before version 5.0, which makes MySQL a big discount in application. MySQL supports stored procedures since version 5.0, which improves both the processing speed of the database and the flexibility of database programming.

Stored procedure is an important function in database. Stored procedure can be used to convert data, migrate data and make reports. It is similar to programming language. Once executed successfully, it can be called at any time to complete the specified function operation.

The use of stored procedures can not only improve the efficiency of database access, but also improve the security of database use.

For callers, stored procedures encapsulate SQL statements, and callers do not have to think about the specific implementation of logical functions. It can be called by programming languages such as Java and C#.

Writing stored procedures is slightly more demanding for developers, but this does not affect the widespread use of stored procedures, because stored procedures have the following advantages:

1)encapsulation

Usually complete a logical function requires multiple SQL statements, and each statement is likely to pass parameters, so writing logical functions is relatively more complex, and stored procedures can include these SQL statements into a separate unit, so that the outside world can not see complex SQL statements, only a simple call can achieve the goal. And database professionals can modify stored procedures at any time without affecting the application source code that calls them.

2)Increase the power and flexibility of SQL statements

Stored procedures can be written with flow control statements, have strong flexibility, and can complete complex judgments and more complex operations.

3)Reduce network traffic

Because the stored procedure runs on the server and executes fast, when the stored procedure is invoked on the client computer, only the invocation statement is transmitted in the network, thereby reducing the network load.

4)high performance

When a stored procedure is successfully compiled, it is stored in the database server and can later be called directly by the client, so that all SQL statements are executed from the server, thereby improving performance. However, it needs to be explained that the more stored procedures are not the better, and excessive use of stored procedures will affect system performance.

5)Improve database security and data integrity

One way to improve security for stored procedures is to use them as intermediate components, where stored procedures can perform operations on certain tables, and then provide stored procedures as interfaces to external programs. In this way, external programs cannot directly operate database tables, but can only operate corresponding tables through stored procedures, so security can be improved to a certain extent.

6)Make data independent

Data independence can be decoupled, meaning that programs can invoke stored procedures instead of executing multiple SQL statements. In this case, the stored procedure isolates the data from the user. The advantage is that when the structure of the data table changes, the table is called without modifying the program, only the database administrator needs to rewrite the stored procedure.

What are the functions of mysql using stored procedures to share here, I hope the above content can be of some help to everyone, you can learn more knowledge. If you think the article is good, you can share it so that more people can see it.
