This article is to share with you about the use of stored procedures in databases. 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.

The role of the stored procedure in the database: 1, the stored procedure can accept parameters, output parameters, return single or multiple result sets and return values; 2, the stored procedure runs stably, there will not be too many errors; 3, the stored procedure mainly runs on the server to reduce the pressure on the client.

The role of stored procedures in the database:

First: the stored procedure runs faster because the SQL statement has been pre-compiled.

Second: stored procedures can accept parameters, output parameters, return single or multiple result sets, and return values. Returns the error reason to the program.

Third: the stored procedure runs stably and there are not too many errors. As long as it is successful once, it will run according to this program in the future.

Fourth: the stored procedure is mainly run on the server to reduce the pressure on the client.

Fifth: stored procedures can include program flow, logic, and queries to the database. At the same time, data logic can be encapsulated and hidden by entities.

Sixth: stored procedures can execute a series of SQL statements in a single stored procedure.

Seventh: stored procedures can reference other stored procedures from within their own stored procedures, which can simplify a series of complex statements.

Extended data:

Advantages of stored procedures:

1. The ability of stored procedure greatly enhances the function and flexibility of SQL language.

2. The security and integrity of the data can be guaranteed.

3. Through the stored procedure, the unauthorized users can access the database indirectly under control, so as to ensure the security of the data.

4. Through the stored procedure, the related actions can occur together, thus the integrity of the database can be maintained.

5. Before running the stored procedure, the database has analyzed the syntax and syntax of the stored procedure, and given the optimized execution scheme. This compiled process can greatly improve the performance of SQL statements.

6. It can reduce the traffic of the network.

7. Put the operation program that embodies the enterprise rules into the database server for centralized control.

Thank you for reading! About the use of stored procedures in the database 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.
