When QAN fails to detect the schema, the Query Abstract show wrong schema. In this case the Tables section for the query shows ``.`_object_state` and the CREATE section below shows: " SHOW CREATE TABLE _object_state: Error 1046: No database selected".
The fingerprint in this case is:
"SELECT `os` . * FROM `_object_state` `os` JOIN `_object_state` `pos` ON `os` . `from_object_state_id` = `pos` . `object_state_id` WHERE `os` . `object_id` = ? AND `pos` . `state_id` = ? ORDER BY `os` . `object_state_id` DESC LIMIT ?"
