Help with resultset and looping thru a sql filed

Question

Hi,
I have a SQL statement which connects two tables with accounting number, the table2 have multiple rows for one accounting number in table1.
So I did if else condition in accounting number in resultset as following:
List<AccRecord> retval = new ArrayList<AccRecord>();
while(rs.next())
//instance of account record
AcciRecord acct1 = new AccRecord();;
               if(acc_No != accountNumber)
                       //then get all data from table1                    
               acc1.setEmpId(rs.getInt("ACC_ID"));
                         acc1.setEmpId(rs.getString("Acc_Name"));//and other 20 fields like this
          else if(acc_No == accountNumber) //this is where it breaks down if same acc number has more than one row in table2,we don't //want to get all other data again from table1
                                             //also get all data associated with that accounting number from table2
                             Other other1 = new Other();                         
                             other1.setEmpId(rs.getInt("EMP_ID"));//these are datas from table2
                             other1.setjobCode(rs.getString("JOB_CD"));
                             other1.add(crew1);
retval.add(acc1);
}My question is how can I make logic right, in above code for the first account number it will go to else if condition (coz very first time acc number is never going to be different then previous accounting number,so it won't get my accounting data, the way I have compared it)
I want to code like for one accounting number it brings all accounting data and for that accounting number it also brings all employee data (which is in table2) which will more than one entires,
So..when accounting number is same as previous it shouldn't get all data again from table 1 ,it should go to only else if condition to get data from table 2 , it should go to my if block only when there is a new accounting number, in other words when there is next record in table1
Can anybody help me??
Please...
Thanks

Answer 1

hi there,
thanks for ur feedback
but it is always going to contian accno .. so it will never go in your condition
May be I haven't explained it well
I need something which gets all data for every new account number in table 1
Now for that same account number, table2 have 3 rows including that account number 3 times (I am connecting this 2 tables with acc no, table 1 doesn't have duplicate acc no but table 2 does)So my resultset runs 3 times for the first record in table 1, because for that accno table 2 has 3 entries
This is because my sql is as follow,,which I have to,,I can't change due to requirements...
SELECT A.accNumber, A.Date, B.EMP_ID, B.JOB_CD
FROM Table A,  Table B,  (SELECT SSA.accNumber FROM Table SSA, Table SSB       
    WHERE SSB.EMP_ID = ?  AND
   SSA.accNumber = accNumber) C          
WHERE A.accNumber = C.accNumber                                            
   AND A.accNumber = B.accNumber                        
//so if I do: like this in my resultset
while(rs.next())
Integer accNumber = rs.getINt(accNumber);
accno =accnumber;
if (accno != accNumber)
{ get all account data
else if(accno == accNumber)
{ get all other data
}but question is it will not satisfy my if condition , because for a new record ,in this case,in first record acc number will never match...
I appreciate your help and time
Please help me
THnaks
