Syntax

SHOW PROCEDURE CODE proc_name

Description

This statement is a MariaDB extension that is available only for servers that have been built with debugging support. It displays a representation of the internal implementation of the named stored procedure. A similar statement, SHOW FUNCTION CODE, displays information about stored functions.

Both statements require that you be the owner of the routine or have SELECT access to the mysql.proc table.

If the named routine is available, each statement produces a result set. Each row in the result set corresponds to one "instruction" in the routine. The first column is Pos, which is an ordinal number beginning with 0. The second column is Instruction, which contains an SQL statement (usually changed from the original source), or a directive which has meaning only to the stored-routine handler.

Examples

DELIMITER //

CREATE PROCEDURE p1 ()
  BEGIN
    DECLARE fanta INT DEFAULT 55;
    DROP TABLE t2;
    LOOP
      INSERT INTO t3 VALUES (fanta);
      END LOOP;
  END//
Query OK, 0 rows affected (0.00 sec)

SHOW PROCEDURE CODE p1//
