MySQL Error 3556: No System Table Access
Description
This error indicates that a user or process attempted an operation on a MySQL system table without the necessary privileges or in an inappropriate context. It typically occurs when trying to query, modify, or create objects within critical internal databases like `mysql`, `information_schema`, or `performance_schema` without authorization.
Error Message
system table
Known Causes
3 known causesInsufficient User Privileges
The MySQL user attempting the operation lacks the necessary `GRANT` privileges (e.g., `SELECT`, `UPDATE`) on the specific system table or database.
Direct Modification of Protected Tables
The operation attempts to directly modify a system table that is managed internally by MySQL and not intended for user-level DML operations.
Incorrect Schema Context
The query implicitly targets a system table due to an incorrect `USE` statement or missing schema qualification, leading to an unauthorized action.
