Failed to grant EXECUTE and ALTER ROUTINE privileges
MySQL raises error 1404 with the condition name ER_PROC_AUTO_GRANT_FAIL and message "Failed to grant EXECUTE and ALTER ROUTINE privileges" when it cannot automatically assign those privileges to the DEFINER of a stored procedure or function.
The server performs an implicit GRANT on the new routine so that the DEFINER can execute and alter it. If that GRANT fails due to missing privileges, nonexistent accounts, or privilege-table corruption, the CREATE statement aborts with this error.
Auto-grant failure usually happens because the DEFINER account does not exist, the statement executor lacks the GRANT OPTION or SUPER privilege, or the mysql.procs_priv table is locked or corrupted.
It can also be triggered when a DEFINER specifies an invalid host part, or when the server runs in SQL modes that treat privilege warnings as errors.
Fixes focus on ensuring the DEFINER account exists and that the session user holds sufficient privileges. Often you only need to create the missing account or run the CREATE statement as a DBA.
If you cannot obtain higher privileges, rewrite the routine with DEFINER = CURRENT_USER so that no automatic grant is required.
Developers hit this error after migrating routines between environments where the original DEFINER account is absent. Creating the account or updating the DEFINER clause removes the blocker.
CI/CD pipelines may see the error if deployment users have CREATE ROUTINE but not GRANT OPTION. Granting GRANT OPTION or delegating routine creation to a privileged role resolves the failure.
Standardize routine deployment by using DEFINER = CURRENT_USER or a dedicated service account that exists in every environment.
Automate privilege checks in Galaxy collections or pre-deployment scripts to ensure the executor holds GRANT OPTION before running CREATE PROCEDURE statements.
Error 1405 ER_PROC_AUTO_REVOKE_FAIL arises during DROP ROUTINE when the server cannot revoke privileges - verify privilege table integrity.
Error 1044 DBACCESS_DENIED_ERROR and 1045 ACCESS_DENIED_ERROR indicate broader permission issues - check user grants and authentication settings.
The user referenced in the DEFINER clause does not exist, so MySQL cannot assign privileges.
The session user can create routines but cannot grant privileges on them, causing the auto-grant to fail.
Issues in mysql.procs_priv or global privilege tables block the GRANT operation.
A wildcard or host that does not match any user entry prevents MySQL from finding the correct account.
Fires when MySQL cannot automatically revoke routine privileges during DROP; often tied to the same privilege-table issues.
Indicates the user lacks permission to access a database; check database-level GRANTs.
Authentication failure due to wrong password or plugin mismatch; resolve credentials.
Appears when attempting to create or drop users without proper rights; grant CREATE USER or SUPER privilege.
No. MySQL always attempts to grant EXECUTE and ALTER ROUTINE to the DEFINER during creation. Use a valid DEFINER or proper privileges instead.
No. Triggers use table-level privileges and do not require the same auto-grant mechanism as stored routines.
Yes, provided the deployment user always has the necessary privileges. This approach avoids hard-coding accounts.
Galaxy’s AI copilot warns when a CREATE PROCEDURE statement uses a nonexistent DEFINER. Teams can endorse corrected queries, reducing production incidents.
