<div class="section"><p>The <a href="javadoc/com/ibm/as400/util/servlet/RowMetaData.html"> RowMetaData</a> class defines an interface
that you use to find out information about the columns of a <a href="rowdata.htm#rowdata"> RowData</a> object. </p>

<div class="section"><p>With the RowMetaData classes you can do the following:</p>
</div>
<div class="section"><ul><li>Get the <a href="javadoc/com/ibm/as400/util/servlet/RowMetaData.html#GETCOLUMNCOUNT()"> number of columns</a></li>
