While condition is taking too much time

Question

I have a query that returns around 2100 records ( not many ! ) , when I am processing my result set with a while condition , it's taking too much time ( around 30 seconds ). Here is the code
public static GroupHierEntity load(Connection con)
     throws SQLException
     internalCustomer=false;
     String customerNameOfLogger = com.photomask.framework.ControlServlet.CUSTOMER_NAME;
if ( customerNameOfLogger.startsWith("DPI") || customerNameOfLogger.startsWith("DUPONT") || customerNameOfLogger==null || customerNameOfLogger.equals("") ||customerNameOfLogger.equals("Unavailable") )
{ internalCustomer=true;}
// System.out.println(" ***************** customer name of logger " + com.photomask.framework.ControlServlet.CUSTOMER_NAME + "internal customer " + internalCustomer);
// show all groups to internal customers and only their customer groups for external customers
if (internalCustomer) {
          stmtLoad = con.prepareStatement(sqlLoad);
     ResultSet rs = stmtLoad.executeQuery();
     return new GroupHierEntity(rs); }
     else
     stmtLoadExternal = con.prepareStatement(sqlLoadExternal);
     stmtLoadExternal.setString(1, customerNameOfLogger);
     stmtLoadExternal.setString(2, customerNameOfLogger);
     // System.out.println("***** sql " +sqlLoadExternal);
     ResultSet rs = stmtLoadExternal.executeQuery();
return new GroupHierEntity(rs);
GroupHierEntity ge = GroupHierEntity.load(con);
while(ge.next())
lvl = ge.getInt("lvl");
oid = ge.getLong("oid");
name = ge.getString("name");
if(internalCustomer) {
if (lvl == 2)
int i = getAlphaIndex(name);
super.setAppendRoot(alphaIndex);
gn = new GroupListDataNode(lvl+1,oid,name);
gn.setSelectable(true);
this.addNode(gn);
count++;
System.out.println("*** count "+ count);
ge.close();
========================
Then I removed every thing in the while clause and just run as it is , still it is taking same time ( 30 secs )
while(ge.next())
{count++;}
Why the while condition ( ge.next() ) is taking so much time ? Is there any other efficient way of reading the result set ?
Thanks ,

Answer 1

I tried all these things. The query is not taking much time ( 1 sec ). but the resultset.next() is taking too much time. I counted the time by putting System.out.pr.. at various points to see whuch is taking how much time.
executeQuery() is only taking 1 sec. Processing the result set ( moving the cursor to next position ) is taking too much time.
I have similar queries that return some 800 rows , that only takes 1 sec.
I have doubt on resultset.next(). Any other alternative ?
