MySQL Error 1100: Table Not Locked
Description
This error indicates that a MySQL operation attempted to access or manipulate a table that was expected to be locked using the `LOCK TABLES` statement, but no such lock was active. It typically occurs when a subsequent operation, like `UNLOCK TABLES`, finds the table in an unlocked state within the current session.

The `LOCK TABLES` statement was not properly executed or was skipped before an operation that expected the table to be locked.
Session State Reset
