One extra candy in Quest w.r.t. queries is the ability to query the database directly. You can do this simply by prefixing your query with the text: /*direct*/ followed by the SQL query you want to execute. This will tell Quest that the rest of the text is a query that should be evaluated by the database. For example:

/*direct*/
SELECT * FROM concept

Direct queries can be used in virtual and classic mode, and are useful for debugging. Also, if you are curious about the in-memory databases created by Quest in classic mode, you can inspect them using direct queries.
