Show procedure code in MySQL

I've tried to show the SQL code of a stored procedure called add_pixel: mysql> SHOW PROCEDURE CODE add_pixel; ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 1 I've made sure that the procedure exists: mysql> CALL add_pixel(); ERROR 1318 (42000): Incorrect number of arguments for PROCEDURE pixels.add_pixel; expected 3, got 0 And SHOW CREATE PROCEDURE works: mysql> SHOW CREATE PROCEDURE add_pixel; +-----------+----------+------------------+----------------------+----------------------+--------------------+ | Procedure | sql_mode | Create Procedure | character_set_client | collation_connection | Database Collation | +-----------+----------+------------------+----------------------+----------------------+--------------------+ | add_pixel | | NULL | utf8 | utf8_general_ci | utf8_unicode_ci | +-----------+----------+------------------+----------------------+----------------------+--------------------+ 1 row in set (0.00 sec) and that my MySQL version supports `SHOW PROCEDURE (SHOW PROCEDURE CODE was added in MySQL 5.0.17 ). How do I view the source SQL code of the procedure?
