java - Prepared statement not working, resultset.next() has no records -


running below java code 

final string qry = queryconstants.query;         connection con = null;         preparedstatement stmt = null;         resultset rs = null;         try {             con = getdatasource().getconnection();             stmt = con.preparestatement(qry);             stmt.setstring(1, abc1);             stmt.setlong(2, abc2);                       stmt.setstring(3, abc3);             long st = system.currenttimemillis();                 rs = stmt.executequery();             long end = system.currenttimemillis();             logger.error("retrialdaoimpl.fetchfailedmessagefromdb:: time taken fetch failed messages::" + (end - st) + "|likepattern::" + likepattern);             while (rs.next()) {                 system.out.println(rs.getstring("version_number"));             }

query below 

select max(version_number) version_number,  tlo_type, tlo_id  msg_xml status ='n' , recoverable_flag ='y' , pattern  =1 ,  rownum <= 100 group tlo_type, tlo_id) t1, msg_xml x  x.tlo_type = t1.tlo_type , nvl(x.tlo_id,1) = nvl(t1.tlo_id,1) , x.vdps_version_number = t1.vdps_version_number , x.status  ='n' , x.recoverable_flag ='y' , x.pattern = 1 order x.retry_count,  x.updated_time

msg_xml view. tried running sql on sql developer returns record why result set not return anything.
