A named index can be used to order the rowset, and to provide fast key-based row retrieval from the table.</p> <p>The <codeph>TDbSeekKey</codeph> class is used to pass a key value to <codeph>RDbTable::SeekL()</codeph>, for lookup in the currently active index on that rowset. It can store a key value of any type. </p> <p><codeph>TDbSeekKey</codeph> can only hold a single-column key. Use the <codeph>TDbSeekMultiKey&lt;TInt S&gt;</codeph> templated class to allow multi-column indexes to be searched using multi-column key values. The template parameter <codeph>S</codeph> specifies the maximum number of column values that can be added to the key value.</p> </conbody></concept>
