SHOW CREATE PROCEDURE

Syntax

SHOW CREATE PROCEDURE proc_name

Description

This statement is a MariaDB extension. It returns the exact string that can be used to re-create the named stored procedure, as well as the SQL_MODE that was used when the trigger has been created and the character set used by the connection.. A similar statement, SHOW CREATE FUNCTION, displays information about stored functions.

Both statements require that you are the owner of the routine or have the SELECT privilege on the mysql.proc table. When neither is true, the statements display NULL for the Create Procedure or Create Function field.

Warning Users with SELECT privileges on mysql.proc or USAGE privileges on *.* can view the text of routines, even when they do not have privileges for the function or procedure itself.

The output of these statements is unreliably affected by the sql_quote_show_create server system variable - see http://bugs.mysql.com/bug.php?id=12719

Examples

Here's a comparison of the SHOW CREATE PROCEDURE and SHOW CREATE FUNCTION statements.

SHOW CREATE PROCEDURE test.simpleproc\G
*************************** 1. row ***************************
           Procedure: simpleproc
            sql_mode: 
    Create Procedure: CREATE PROCEDURE `simpleproc`(OUT param1 INT)
                      BEGIN
                      SELECT COUNT(*) INTO param1 FROM t;
                      END
character_set_client: latin1
collation_connection: latin1_swedish_ci
  Database Collation: latin1_swedish_ci

SHOW CREATE FUNCTION test.hello\G
*************************** 1. row ***************************
            Function: hello
            sql_mode:
     Create Function: CREATE FUNCTION `hello`(s CHAR(20))
                      RETURNS CHAR(50)
                      RETURN CONCAT('Hello, ',s,'!')
character_set_client: latin1
collation_connection: latin1_swedish_ci
  Database Collation: latin1_swedish_ci

When the user issuing the statement does not have privileges on the routine, attempting to CALL the procedure raises Error 1370.

CALL test.prc1();
Error 1370 (42000): execute command denieed to user 'test_user'@'localhost' for routine 'test'.'prc1'

If the user neither has privilege to the routine nor the SELECT privilege on mysql.proc table, it raises Error 1305, informing them that the procedure does not exist.

SHOW CREATE TABLES test.prc1\G
Error 1305 (42000): PROCEDURE prc1 does not exist
