InnoDB does the following check for sequence table during check table command: - There should be only one index should exist on sequence table - There should be only one row should exist on sequence table - The leaf page must be the root page for the sequence table - Delete marked record should not exist - DB_TRX_ID and DB_ROLL_PTR of the record should be 0 and 1U << 55
