Question

Does anyone know what is the syntax for renaming a mysql stored procedure/function? Or is this even supported in MySQL? I’ve been googling this for several minutes…

Answer 1

try this

 UPDATE `mysql`.`proc`
SET name = '<new_proc_name>',
specific_name = '<new_proc_name>'
WHERE db = '<database>' AND
  name = '<old_proc_name>';

Also note: If have granted privileges to users for this procedure you will need to update the procedure name in procs_priv as well.

UPDATE `mysql`.`procs_priv`
SET Routine_name = '<new_proc_name>'
WHERE Db = '<database>' AND
  Routine_name = '<old_proc_name>';
 FLUSH PRIVILEGES;
