java - Oracle ERROR invalid number -

i have table this:

arithmos kod date         b c 1        ΑΓΟ 01/08/2016   5 2 3 2        ΠΛΗ 02/08/2016   3 2 1 

and netbeans program want insert name table , date , kod , rows meet criteria.

code:

string pote=ac3.gettext();//name table  string c=((jtextfield)jdt1.getdateeditor().getuicomponent()).gettext();//date       string d=((jtextfield)jdt2.getdateeditor().getuicomponent()).gettext();//date string s0=(string)jcb1.getselecteditem();//kod  string sql="select * "+pote+" (hmerominia between "+c+" , "+d+") , kod='"+s0+"' order arithmos";  

if (re == joptionpane.yes_option) { try{

    stm=(oraclestatement) conn.createstatement(rs.type_scroll_insensitive,rs.concur_updatable);       rs = (oracleresultset) stm.executequery(sql);     updatejtable();   /* while(rs.next()){         v0.settext(rs.getstring("arithmos"));      }*/  } catch(exception e1){     joptionpane.showmessagedialog(null, e1); }      }else if (re == joptionpane.no_option) {         this.setvisible(true);     } 

error showing invalid number.

fixed:
