Yes, <esql:get-column-count/> does it. Thus
<esql:row-results>
<tr>
<xsp:logic>
for (int i=0; i < <esql:get-column-count/>; i++) {
<td><esql:get-column><esql:param
name="column"><xsp:expr>i</xsp:expr></esql:param/></td>
}
</xsp:logic>
</tr>
</esql:row-results>
would output all columns in a table. But for this you could also do
<esql:row-results>
<tr>
<esql:get-columns/>
</tr>
</esql:row-results>
which would produce a similar result (not the same, as ex.2 does not
use <td/> tags but column names... so the result would need to be
transformed properly)
Chris.
