The following SQL will show you the current rank of your query for today. If the query doesn't make the top N for the day, it may get cleaned out of CONSW_X and the data will be no longer exist.
You will need to know the SQLHASH of the query you are interested in as well as the database id of the monitored database. Change CONSW_X to the database id (ie. CONSW_1).
