Query based on query
  Available only with these kinds of connection
A query of query is a query performed from items coming from another query. The initial query must have been run before the query based on query. This type of query is available: Caution: Do not confuse "Query based on query" and "Sub-query". For more details, see Sub-query. Limitation: The queries based on queries are not available for the external databases (via OLE DB, ODBC or Native Access). Indeed, the database does not know the source query from which the second query is created.
