I was just surprised because I've never run into that
This is the wrong list i'm pretty sure but there are a couple of ways to get the
number but there isnt a direct method that returns it.
If the result set is scrollable you can iterate through it counting the number of
iterations, then set it back to the start when you want to process the

If the cursor is non scrollable, this will only work once.
It is better for you to execute a Select count(1) ... query, to find out how many
results you would get back. Or even better,
execute a stored procedure that returns the count as an

Thanks Adam :)
First of all I subscribe to the list yesterday and I m
new to JSP. Secondly could u plz tell me right list
name so I can subscribe to that.
Adam, I did exactly the same way u mentioned, but when
I use like
//---
ResultSet rs = stmt.executeQuery(query);
The first code will work if when you create your statement object you define it as
scrollable.
Statement stmt =
con.createStatement(
ResultSet.TYPE_SCROLL_INSENSITIVE,
ResultSet.CONCUR_READ_ONLY);

first code = result set not scrollable, you can only loop through it once

First of all forgive me for being very stressed and tired - All I did
was put into some kind of code model a suggestion previously put forward
by Matt:

you want to
Adam - I mentioned this in another post but unless the result set is scrollable then
you can't reset it back to the beginning. You need to declare the statement object as
scrollable when you create it to achieve this. So Filip was right in that it will only
work once with the default behaviour.
