OK this helps, but what I am trying to do is to generate a general report
for any table - if I use the following dtml - how do I access the actual
data retrieved by the query? I could call the query again and get the data
but in terms of efficiency that is not too practical. I have looked for the
dtml that is called when a query is tested but haven't found it yet!
<dtml-with "queries.qrytest()">
<table border=1 >
        <tr>
                <dtml-in names>
                        <th><dtml-var sequence-item></th>
                </dtml-in>
        </tr>
<dtml-comment> I WANT TO PUT THE DATA FROM THE QUERY HERE </dtml-comment>
        <tr>
                <dtml-in ??????>
                        <td><dtml-var ????></td>
                </dtml-in>
        </tr>
</table>
</dtml-with>
Here is some tested DTML code to create an HTML table from any given SQL
query:
<table border="1">
<dtml-with name="sqlMethod">
    <tr>
    <dtml-in name="names">
        <th>&dtml-sequence-item;</th>
    </dtml-in>
    </tr>
    <dtml-in name="dictionaries">
        <tr>
        <dtml-in name="values">
            <td>&dtml-sequence-item;</td>
        </dtml-in>
        </tr>
    </dtml-in>
</dtml-with>
</table>
Actually, that may not put the values under the right columns, try this
instead:

<table border="1">
<dtml-with name="sqlMethod">
    <dtml-in name="dictionaries">
        <dtml-if name="sequence-start">
            <tr>
            <dtml-in name="keys">
               <th>&dtml-sequence-item;</th>
            </dtml-in>
            <tr>
        </dtml-if>
        <tr>
        <dtml-in name="values">
            <td>&dtml-sequence-item;</td>
        </dtml-in>
        </tr>
    </dtml-in>
</dtml-with>
</table>
