want to view those items that have been ordered in the last 14 days. To specify

LAST_ORDER_DATE > CURRENT DATE - 14 DAYS</kbd>. You can select the elements

you can enter them in the <span class="uicontrol">Clause</span> field.</span></li>

new names. The schema that the view is created into does not need to be the

same schema as the table it is built over. You can use any schema.</p>
