By default, the SQL terminal reuses existing connections. When multiple queries are queued for execution in an existing connection, consider using a new connection to avoid delays caused by sequential execution. However, it is best to reuse existing connections when working with temporary tables. For how to edit temporary tables, see <a href="DWS_DS_020.html">Editing Temporary Tables</a>.</p>
