<p>Error 1370 indicates the current MySQL user lacks sufficient privileges to execute, alter, or drop the specified stored procedure or function.</p>
<p>MySQL Error 1370: ER_PROCACCESS_DENIED_ERROR occurs when the current user does not have EXECUTE or ALTER privilege on a stored routine. Grant EXECUTE (and, if needed, ALTER) on the routine or its database to the user, then re-run the command to resolve the issue.</p>
%s command denied to user '%s'@'%s' for routine '%s'
MySQL throws Error 1370 when it blocks a user from running a command on a stored routine because the user lacks the required privilege. The complete message is "%s command denied to user '%s'@'%s' for routine '%s'".
The message clearly identifies the command (EXECUTE, ALTER, DROP, etc.), the user and host, and the routine that triggered the denial. Fixing the error requires granting the missing privilege or changing the routine's definer.
The error fires when MySQL evaluates the user's privileges and finds that EXECUTE, ALTER ROUTINE, or DROP ROUTINE is missing for the target procedure or function.
It often appears after migrating databases, restoring from dumps, or switching to more restrictive permission policies. Shared hosting and CI pipelines frequently hit this error because service accounts run with minimal rights.
Identify the missing privilege by reading the first word of the error message (EXECUTE, ALTER, or DROP). Grant that privilege on the routine or on the entire database to the affected user.
After applying the GRANT statement, flush privileges or reconnect so changes take effect. If the routine's DEFINER no longer exists, recreate the routine with a valid definer that has the right privileges.
Application startup scripts may call stored procedures during deployment. Grant EXECUTE on those routines to the deployment user to eliminate failures.
CI tools often drop and create routines. Grant CREATE ROUTINE and ALTER ROUTINE to the CI user in addition to EXECUTE.
Provision least-privilege accounts with the exact rights they need, but remember to include EXECUTE for any routine they must call.
Version-control your GRANT statements and run them as part of migrations. Galaxy workspaces can store and endorse these scripts, ensuring teams apply privileges consistently.
Error 1044 (ER_DBACCESS_DENIED_ERROR) signals missing privileges on a database. Fix it with GRANT ALL ON db.* TO user@host.
Error 1227 (ER_SPECIFIC_ACCESS_DENIED_ERROR) covers general privilege denials. Inspect command and grant the specific right.
The user attempts to call a stored procedure but lacks EXECUTE on that routine or its database.
The user tries to alter a routine without ALTER ROUTINE rights.
The routine was created with a definer that no longer exists, so privilege checks fail for INVOKER users.
The user connects from a host not covered by the existing GRANT statement, causing privilege lookup to fail.
Permission denied on database level. Grant database privileges.
Generic privilege denial for various SQL commands.
SUPER privilege required to create or alter routines when binary logging is enabled.
Granting EXECUTE on the database covers all current and future routines, while granting on a single routine limits access to that specific object.
No. FLUSH PRIVILEGES only reloads the grant tables. You must first GRANT the missing privilege.
Yes. If SQL SECURITY DEFINER is used, the definer's privileges determine access. A dropped or under-privileged definer causes error 1370.
Galaxy stores and versions GRANT scripts alongside queries, ensuring teams apply correct privileges during migrations and reviews.
