What is the MySQL command to view the definition of a stored procedure or function, similar to sp_helptext in Microsoft SQL Server?

I know that SHOW PROCEDURE STATUS will display the list of the procedures available. I need to see a single procedure's definition.

SHOW CREATE PROCEDURE <name>

Returns the text of a previously defined stored procedure that was created using the CREATE PROCEDURE statement. Swap PROCEDURE for FUNCTION for a stored function.

You can use this:

SELECT ROUTINE_DEFINITION FROM INFORMATION_SCHEMA.ROUTINES
WHERE ROUTINE_SCHEMA = 'yourdb' AND ROUTINE_TYPE = 'PROCEDURE' AND ROUTINE_NAME = "procedurename";
user_743140 
SHOW CREATE PROCEDURE proc_name;

returns the definition of proc_name

You can use table proc in database mysql:

mysql> SELECT body FROM mysql.proc
WHERE db = 'yourdb' AND name = 'procedurename' ;

Note that you must have a grant for select to mysql.proc:

mysql> GRANT SELECT ON mysql.proc TO 'youruser'@'yourhost' IDENTIFIED BY 'yourpass' ;

something like:

DELIMITER //

CREATE PROCEDURE alluser()
BEGIN
   SELECT *
   FROM users;
END //

DELIMITER ;

than:

SHOW CREATE PROCEDURE alluser

gives result:

'alluser', 'STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER', 'CREATE DEFINER=`root`@`localhost` PROCEDURE `alluser`()
BEGIN
   SELECT *
   FROM users;
END'
