Retrieving all FK from child table in a resultset

Question

I have a parent and its child table.In child table there are many records containing the same PK of the parent as a foreign key(one to many relationship).Now how can I get all those values (in a resultset) of child table containing the same FK .The code i produced can fetch the first record of the same PK of the parent.But how can I get all with a single SQl statement and iterate through them as necessary.
String sql1="SELECT * FROM ChildTableName WHERE id= ' 100 ' ; //100 is the PK of Parent table // there are many records in Child Table having 100 as foreign key resultset = statement.executeQuery(sql1); resultset .next();      try{          System.out.println("Data> "+resultset.getString(1));         System.out.println("Data> "+resultset.getString(2));         System.out.println("Data> "+resultset.getString(3));   }catch(SQLException sqle){System.out.println("ERROR REFRESH : " + sqle); }{code} Edited by: Tanvir007 on Apr 17, 2008 4:35 AM Edited by: Tanvir007 on Apr 17, 2008 4:37 AM Edited by: Tanvir007 on Apr 17, 2008 4:40 AM

First of all,ARE U BLIND brother, didn't you see what I wrote-
String sql= "SELECT Flat_Rent.rent_id,Flat_Rent.flat_name FROM Month_Rent INNER JOIN Flat_Rent ON Month_Rent.rent_id = Flat_Rent.rent_id WHERE Flat_Rent.rent_id = '4-2008'" ;      
Actually, I did see that. It makes me wonder why you were asking in the first place and what the problem is now.In the first place, I didnt use join,I did it later as u advised.But u asked me later about the join.Why?

People who have empty catch blocks are fools. If you don't want to be one, log or print the stack trace. It's good information to have, and it'll help you avoid problems in the future.People are fools for many reasons LIKE - even if I told u that I can retrieve record (but only the first record),there is no question of throwing an exception.And I DID fill catch block in the first place,look back.Later, it wasnt that much necessary bcos no exception throws at all.
However brother many thanks for an attempt to help me.I think I have solved the problem-
try{
String sql= "SELECT flat_name,flat_rent,elec_bill FROM Month_Rent INNER JOIN Flat_Rent ON Month_Rent.rent_id = Flat_Rent.rent_id WHERE Flat_Rent.rent_id = '4-2008'" ;      
                         resultset = statement.executeQuery(sql);               
                         resultset .next();
                         do
                              System.out.println("Flat Name>> " + resultset .getString(1));
                              System.out.println("Rent>> " + resultset .getString(2));
                              System.out.println("Elec Bill>> " + resultset .getString(3));
                         while(rs.next());
                    }catch(SQLException sqle){ sqle.printStackTrace();           }But the problem is, The fields in my DB are in this serial- rent_id,flat_name,flat_rent,elec_reading,elec_bill,total_rent,status
But as you can see from the code that I get the Flat name in 1,Rent in 2 and bill in 3 which should be 2,3,5 respectively.Can you tell me why it is so?
