A very basic question: a dtml-in loop calls an zsql method
it works fine when there is data but when there is no data
it should display no records found. But it displays nothing when
there are no records. Please suggest a soultion
<dtml-in     "select_something(parameter=parameter 
,parameter1=parameter1)">
<dtml-if "_['sequence-start']==_['sequence-end']">
no records found
<dtml-else>
<dtml-var fieldname>
</dtml-if>
</dtml-in>
<dtml-in>
     work with content here
<dtml-else>
     if no content, dtml-in passes control here
</dtml-in>
