Problem getting correct data from MS Access after doing an Update

Question

Hi all,
I have a problem getting correct data after doing an update. This is the scenario
I am selecting some(Eg: All records where Column X = �7� ) records and update a column with a particular value (SET Column X = �c� ) in all these records by going through a while loop. In the while loop I add these records to a vector too, and pass it as the return value.
After getting this return value I go through a for loop and get each record one by one from the DB and check if my previous update has actually happened. Since No errors were caught while updating DB, I assume all records are updated properly but my record set shows one after another as if it has not been updated. But if I open the DB it is actually updated.
This does not happen to all records, always it shows like this
1st record     Mode = �c�
2nd record     Mode = �7�
3st record     Mode = �c�
4nd record     Mode = �7�
9th record     Mode = �c�
10th record     Mode = �7�
I am relatively new to java and this is someone elses code that I have to modify,So I am not sure if there some thing wrong in the code too
//Here is the method that gets records and call to update and add to vector
public static Vector getCanceledWorkOrders() throws CSDDBException{
//Variable declaration
  try {
    objDBConn = DBHandler.getCSDBCon();
    strSQL  = "SELECT bal bla WHERE [Detailed Mode])=?)";
    objStmt = objDBConn.prepareStatement(strSQL);   
    objStmt.setString(1, '7');
    objWOPRs = objStmt.executeQuery();
    while (objWOPRs.next()) {
     //Add elements to a vector by getting from result set
      //updating each record as PROCESSING_CANCELLED_WO(c)
      iRetVal = WorkOrderDetailingPolicy.updateRecordStatus(objPWODP.iWorkOrderNumber, objPWODP.strPersonInformed, EMSConstants.PROCESSING_CANCELLED_WO);
      if (iRetVal == -1) {
        throw new NewException("Updating failed");
  catch (Exception e) {
    vecWONumbers = null;
    throw new CSDDBException(e.getMessage());
  }finally{
    try {
      objWOPRs.close();
      objStmt.close();
      DBHandler.releaseCSDBCon(objDBConn);
    catch (Exception ex) {}
  //return vector
//here is the code that actually updates the records
public static int updateRecordStatus(int iWONumber, String strPerInformed , String strStatus) throws CSDDBException{
   PreparedStatement objStmt = null;
   Connection objDBConn  = null;
   String strSQL = null;
   int iRetVal = -1;
   try{
     objDBConn  = DBHandler.getCSDBCon();
     objDBConn.setAutoCommit(false);
     strSQL = "UPDATE Table SET [Detailed Mode] = ? WHERE bla bla";
     objStmt = objDBConn.prepareStatement(strSQL);
     objStmt.setString(1, strStatus);    
     objStmt.execute();
     objDBConn.commit();
     iRetVal = 1;
   }catch(Exception e){
     iRetVal = -1;
   }finally{
     try{
       objStmt.close();
       DBHandler.releaseCSDBCon(objDBConn);
     }catch(Exception ex){}
   return iRetVal;
//Here is the code that call the records again
  public static WorkOrderDetailingPolicy getWorkOrders(int iWorkOrderNo) throws CSDDBException{
    Connection objDBConn = null;
    PreparedStatement objStmt = null;
    ResultSet objWOPRs = null;
    WorkOrderDetailingPolicy objPWODP = null;
    String strSQL = null;
    try {
      objDBConn = DBHandler.getCSDBCon();    
      strSQL = "SELECT * FROM [Work Order Detailing] WHERE [Work Order No] = ?";
      objStmt = objDBConn.prepareStatement(strSQL);
      objStmt.setInt(1, iWorkOrderNo);
       objWOPRs = objStmt.executeQuery();
      if (objWOPRs.next()) {
        objPWODP = new WorkOrderDetailingPolicy();
        objPWODP.iWorkOrderNumber = objWOPRs.getInt("Work Order No");
        //......Get Record values
    catch (Exception e) {
      objPWODP = null;
      throw new CSDDBException(e.getMessage());
    }finally{
      try {
        objWOPRs.close();
        objStmt.close();
        DBHandler.releaseCSDBCon(objDBConn);
      catch (Exception ex) {}
    return objPWODP;
  }

Hello,
Can you put an example of your problem online?
Are you sure you're not having problems with case sensitive data?
Thanks,
