When an Oracle user requests an explain plan on a query, Oracle must inert the rows into an explain table. Toad Data Point creates this table. This is the QUEST_TEMP_EXPLAIN table.
On the connections page under the OCI section is the field to specify the location of an existing explain plan table to use instead of Toad automatically creating one for you when you execute a statement. This is useful if you do not have the required permissions to create explain plan tables or want to use an existing table.
