| Sets the idle query timeout value for the session, in seconds. Queries that sit idle for longer than the |
| timeout value are automatically cancelled. If the system administrator specified the |
| <codeph>--idle_query_timeout</codeph> startup option, <codeph>QUERY_TIMEOUT_S</codeph> must be smaller than |
| or equal to the <codeph>--idle_query_timeout</codeph> value. |
