Editor to share with you what is the use of sql stored procedures, I believe most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

Sql stored procedures are programmable functions that are created and saved in the database. They consist of SQL statements and control structures. They are stored in the database and can be called by client applications.

Sql stored procedure

A stored procedure is an encapsulated process composed of some SQL statements and control statements, which resides in the database and can be called by the client application. The user can call and execute the stored procedure by specifying the name of the stored procedure and given parameters (if the stored procedure has parameters), or from another procedure or trigger.

Stored procedures are programmable functions that are created and saved in the database and can be composed of SQL statements and control structures. Stored procedures are useful when you want to execute the same function on different applications or platforms, or to encapsulate specific functions. The stored procedure in the database can be seen as a simulation of the object-oriented method in programming, which allows you to control how the data is accessed.

Stored procedure type

Depending on the type of return value, stored procedures can be divided into three categories: stored procedures that return recordsets, stored procedures that return numeric values (also known as scalar stored procedures), and behavioral stored procedures.

1. A stored procedure that returns a recordset: the result of its execution is a recordset. A typical example is to retrieve records from a database that meet one or more conditions.

2. A stored procedure that returns a value: returns a value after execution, such as executing a function or command with a return value in the database

3. Behavior stored procedure: it is only used to implement a function of the database without returning a value, such as update and delete operations in the database.
