Re: conditionally add a table to the from clause just once if either or both of two parameters is not empty

[Koka Kiknadze]

<isNotEmpty property="supplierCompanyId">
       , suppliers_for_parts sp
</isNotEmpty>

<isEmpty property="supplierCompanyId">
   <isNotEmpty property="supplierRef">
        , suppliers_for_parts sp
    </isNotEmpty>
</isEmpty>

another ugly way I guess.
