for (int i=0;i<retlist.size (); i++) {
Record map = (record) retlist.get (i);
Object ob = Map.get ("A25");//first turn data into
Str_a25=ob.tostring ();
String ls_sql2= "Select A27,a28,sum (A13) A13 from GKKC where a13>0 and a25=" +str_a25+ "Group by A27,a28";
list<record> retlist2 = Db.find (LS_SQL2);
Add a list detail
Map.set ("Listmx", retlist2);
}
