This article will explain in detail whether mysql can support stored procedures. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

Mysql has supported stored procedures since version 5. 0. Stored procedures were not previously supported in the MySQL5.0 version, which greatly reduced the application of MySQL. MySQL has supported stored procedures since version 5.0, which not only improves the processing speed of the database, but also improves the flexibility of database programming.

Stored procedures are supported in MySQL version 5. 0.

A stored procedure (Stored Procedure) is a database object that stores complex programs in a database for external programs to call.

A stored procedure is a set of SQL statements for a specific function, which is compiled, created and saved in the database, and can be called and executed by the user by specifying the name of the stored procedure and giving parameters (when needed).

The idea of stored procedure is very simple, which is the code encapsulation and reuse at the level of database SQL language.

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

For the caller, the stored procedure encapsulates the SQL statement, and the caller does not need to consider the specific implementation process of the logic function. It's just a simple call, which 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, multiple SQL statements are needed to complete a logic function, and parameters are likely to be transferred between each statement, so writing logic functions is relatively complicated, and stored procedures can include these SQL statements in a separate unit, so that complex SQL statements can not be seen by the outside world, and only simple calls are needed to achieve the purpose. 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

When the stored procedure is successfully compiled, it is stored in the database server, and the client can call it directly later, so that all SQL statements will be executed from the server, thus improving performance. However, it should be noted that the more stored procedures, the better, too much use of stored procedures will affect system performance.

5) improve database security and data integrity

One way to improve the security of a stored procedure is to use it as an intermediate component. Some tables can be manipulated in the stored procedure, and then the stored procedure can be provided to external programs as an interface. In this way, external programs can not directly manipulate database tables, but can only operate the corresponding tables through stored procedures, so to a certain extent, security can be improved.

6) make the data independent

The independence of data can achieve the effect of decoupling, that is, the program can call stored procedures instead of executing multiple SQL statements. In this case, the stored procedure isolates the data from the user, and the advantage is that when the structure of the data table changes, the calling table does not need to modify the program, but only needs the database manager to rewrite the stored procedure.
