[Zope] what if the query gives no records?

2007-04-10 Thread siva k 

Hi,

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

thanks,
