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

mysql> CALL add_pixel();
ERROR 1318 (42000): Incorrect number of arguments for PROCEDURE pixels.add_pixel; expected 3, got 0
和SHOW CREATE PROCEDURE作品：
mysql> SHOW CREATE PROCEDURE add_pixel;
