hi you should see the resultset-object as a collection of references/pointers to the database, fields in the database, the cursor, etc. This means that once you reuse, close or otherwise decouple the connection from the first resultset, the data you wanted to read from that resultset isn't readable anymore. So, if you really need to (if you can't solve this with a join or group/order by), you should call the other query using a different connection. hope this helps
