MySQLERRORNotableSecurity / PrivilegesHIGH confidence

Insufficient privileges to view procedure/function with column-level grants

Production Risk

Low — the user simply cannot view the routine definition.

What this means

ER_VIEW_OTHER_USER (1448, SQLSTATE HY000) is raised when a user attempts to view a stored procedure or function that requires column-level grant access they do not have.

Why it happens
  1. 1User lacks the necessary column-level privileges to inspect the routine definition
  2. 2SHOW CREATE PROCEDURE/FUNCTION called by a user without sufficient grants
How to reproduce
trigger — this will error
trigger — this will error
SHOW CREATE PROCEDURE sensitive_proc;
-- Called by a user without SHOW_ROUTINE or CREATE ROUTINE privilege

expected output

ERROR 1448 (HY000): The user specified as a definer ('other_user'@'host') does not exist

Fix

Grant appropriate privileges

Grant appropriate privileges
GRANT SHOW_ROUTINE ON *.* TO 'my_user'@'localhost';
-- Or for older MySQL versions:
GRANT SELECT ON mysql.proc TO 'my_user'@'localhost';

Why this works

The SHOW_ROUTINE privilege (MySQL 8.0+) or SELECT on mysql.proc allows viewing routine definitions.

Version notes
MySQL 8.0

SHOW_ROUTINE privilege was introduced; use it instead of SELECT on mysql.proc.
