<concept id="GUID-39897348-B27A-5C02-B65C-C26D122BCAE4" xml:lang="en"><title>Tables</title><shortdesc>Describes how to manipulate tables in the database.</shortdesc><prolog><metadata><keywords/></metadata></prolog><conbody>

<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>
