Dear
Rama,
To
know the number of records returned, use the following two lines of
code.
rs.last(); //moves the control to the last
record
int
count = rs.getRow(); //gets the row count
Thanks and
Regards,
Surya.

Hi,
I wonder how to know if the query returned is empty
or not.
I use this code:
ResultSet rs = stmt.executeQuery("SELECT *
FROM user");
if (rs.next()) {
while (rs.next())
{
out.println("username " +
rs.getString("username"));
}
}
else {
out.println("No record found");
}
but it always skips the first
line of the record.
1. How to know if the query returned is empty or
not.
2. Also, is there any way to know how many records
returned?
Thank
you,
Rama
