duplicate record in query.extend.where.in.zoom

hiii gurus,

I need a help in query.extend.where.in.zoom.
(Scenario)
field.orno.from:
   before.zoom:
   selection.filter:
      query.extend.select.in.zoom("tdcsl491.orno")
      query.extend.from.in.zoom("tdcsl491")
      query.extend.where.in.zoom("tdpur400.orno = tdcsl491.orno)
- i have used two table in query.extend.
- on above example tdpur400.orno has only one record but tdcsl491.orno has a multiple record.
So, When i am trying to open the zoom button,it show me many duplicate record...

Is that possible to get single/Unique record on  "query.extend.where.in.zoom" ???


Thanks in Advance,
DPatel

An easy approach would be to use exists in the where clause instead of equi-join.
However the above approach could become costly on the DB.
