−
<p>Two classes and a template class are used to manipulate tables in the database.</p>+
−
<p>The <codeph>RDbTable</codeph> class is used to manipulate a named table+
−
in the database, providing access to the data as a rowset. 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>+
