You use the Freeform Query option to build queries using temporary tables, extra buffers, and preprocessor statements. Once you choose the Freeform option, you cannot return to using the Query Builder to maintain freeform queries, and can only maintain the query (and browse fields if the query is for a BROWSE object) through the Source view or Source Editor.
Choose from the radio set whether to change the selected query to a freeform query or cancel the operation.
