Result set properties

Question

I have created a class that uses a result set object. I need to scroll through the result set twice and my code is not working. My first question is:
Is there a method that will return the length of a result set?
If there is a length method that will solve my problem. Otherwise from what I understand if I set my result set to have the following properties it will work:
(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_READ_ONLY)
In the API it states that you pass the above as a parameter to the createStatement method. However in our application we do not use the createStatement method. I am wondering is there any other way of setting the result set to have these values?
The problem is occuring with the following method:
public boolean selectEngsByClientName (TransactionManager tm) throws Exception
boolean foundData = false;
ResultSet clientResultSet = null;
PreparedStatement prepStatement = null;
String sqlStatement;
int i = 0;
int countResultSet = 0;
sqlStatement = " SELECT " +
" eg.eng_engagement_no engNo, " +
" cl.cln_short_name clientName, " +
" eg.eng_name engName " +
" FROM " +
" far.engagements eg, " +
" far.clients cl" +
" WHERE " +
" upper(cl.cln_short_name) like upper('" + this.clientSearchName +"%') AND" +
" eg.cln_client_no = cl.cln_client_no AND" +
" eg.eng_status_code = '2'";
try
// Instantiate prepared statement using the connection in the TransactionManager class
prepStatement = tm.getConnection().prepareStatement(sqlStatement);
// Execute the sql statement
tm.startTransaction();
clientResultSet = prepStatement.executeQuery();
//Determines number of objects in result set so that array size can be set
while (clientResultSet.next())
countResultSet ++;
//Creates array of engagement objects that is the same length as the result set
engagement = new Engagement[countResultSet];
for (int index = 0; index < engagement.length; index++)
engagement[index] = new Engagement();
clientResultSet.first();
while (clientResultSet.next())
// Populate DAO attributes with data in the ResultSet returned
System.out.println(clientResultSet.getString("engNo"));
engagement.setEngNo(clientResultSet.getString("engNo"));
engagement[i].setClientName(clientResultSet.getString("clientName"));
engagement[i].setEngName(clientResultSet.getString("engName"));
i ++;
// Set the result to success
foundData = true;
tm.endTransaction();
catch (SQLException sqle)
tm.rollback();
// Re-throw custom exception
throw new Exception();
finally
// Close the prepared statement and result set if not null
try
if (clientResultSet != null)
clientResultSet.close();
if (prepStatement != null)
prepStatement.close();
catch (Exception e) {}
return foundData;

Good atleast ur concepts are clear
ok then do both the thing simultaneously this way
engagement.setClientName(clientResultSet.getString("clientName"));
engagement.setEngName(clientResultSet.getString("engName"));
ResultSet rs=St.executeQuery()
int count=0;
While(rs.next())
count=count+1;
engagement.setClientName(rs.getString("clientName"));
engagement.setEngName(rs.getString("engName"));
System.out.println("Length od ResultSet = "+count);
