Known Causes
3 known causesSchema Deleted Accidentally
A database schema was inadvertently removed, but its references persist within the SDI of other database objects (e.g., tables, views) that were not properly cleaned up.
Incomplete Database Migration
During a database migration or restore, not all required schemas were transferred or recreated, leading to dangling references in the SDI of imported objects.
Corrupted Internal Metadata
MySQL's internal data dictionary information (SDI) has become corrupted, leading to incorrect or invalid references to schemas that do not exist.
