execute/create/alter/drop command denied for routine

Production Risk

Medium — application features depending on stored routines fail.

What this means

The user does not have the required privilege (EXECUTE, CREATE ROUTINE, ALTER ROUTINE, or DROP) on the specified stored routine.

Why it happens
  1. 1User lacks EXECUTE privilege when calling a procedure or function
  2. 2User lacks ALTER ROUTINE or DROP privilege when modifying or dropping routines
  3. 3Routine defined with SQL SECURITY DEFINER and the definer no longer has the required privileges
How to reproduce
trigger — this will error
trigger — this will error
CALL my_proc(); -- user lacks EXECUTE privilege

expected output

ERROR 1370 (42000): execute command denied to user 'user'@'host' for routine 'db.my_proc'

Fix 1

Grant EXECUTE privilege

Grant EXECUTE privilege
GRANT EXECUTE ON PROCEDURE db.my_proc TO 'user'@'host';

Why this works

Allows the user to call the procedure.

Fix 2

Grant all routine privileges

Grant all routine privileges
GRANT CREATE ROUTINE, ALTER ROUTINE, EXECUTE ON db.* TO 'user'@'host';

Why this works

Covers create, alter, and execute operations on routines.
