View stored procedures and their definitions that have been created in MySQL

In MySQL, you can use a variety of methods to view stored procedures that have been created. Here are some commonly used methods:

Method 1: UseSHOW CREATE PROCEDURE

You can useSHOW CREATE PROCEDURECommand to view the definition of stored procedures. This will display the full SQL statement that creates the stored procedure.

Example

Suppose you want to view the nameload_dataThe stored procedure can be used with the following command:

SHOW CREATE PROCEDURE load_data;

This returns two columns:ProcedureandCreate Procedure。ProcedureThe column displays the name of the stored procedure.Create ProcedureThe column displays the complete SQL statement that creates the stored procedure.

Method 2: UseINFORMATION_SCHEMA.Routinessurface

MySQLINFORMATION_SCHEMAThe database contains information about all stored procedures. You can queryINFORMATION_SCHEMA.Routinestable to get detailed information of stored procedures.

Example

If you want to view information about all stored procedures, you can use the following query:

SELECT * FROM INFORMATION_SCHEMA.Routines
WHERE ROUTINE_TYPE = 'PROCEDURE';

If you want to view information about a specific stored procedure, you can use the following query:

SELECT * FROM INFORMATION_SCHEMA.Routines
WHERE ROUTINE_TYPE = 'PROCEDURE' AND ROUTINE_NAME = 'load_data';

This will return various properties of the stored procedure, includingROUTINE_DEFINITION, which contains the complete SQL statements that create stored procedures.

Method 3: Usesurface

MySQLmysqlThere is a name in the databaseprocThe table contains information about all stored procedures. You can also query this table to get information about stored procedures.

Example

Query all stored procedures:

SELECT * FROM 
WHERE type = 'PROCEDURE';

Query a specific stored procedure:

SELECT * FROM 
WHERE type = 'PROCEDURE' AND db = 'your_database_name' AND name = 'load_data';

Please note that queryThe table may require administrator permissions.

Method 4: UsesourceOrder

If you know the path to the created script file for the stored procedure, you can also usesourceCommand to view the definition of stored procedures.

Example

Assume that the stored procedure creation script is located in/path/to/your_script.sql, you can use the following command:

source /path/to/your_script.sql;

This will execute all SQL commands in the script file, including commands that create stored procedures.

Method 5: View the stored procedure documentation

If you use comments when creating stored procedures, you can also view the documentation for stored procedures. This is usually a comment added at the beginning of the stored procedure.

Summarize

  • useSHOW CREATE PROCEDUREis the easiest way to view the definition of a stored procedure.
  • QueryINFORMATION_SCHEMA.RoutinesTables can obtain more detailed stored procedure information.
  • If you have permissions, you can checksurface.
  • usesourceCommands can view the script for creating stored procedures.
