Getting the record count from result set

Question

i'm retreiving the result set using the executeQuery method, now i want to know how many records are there in the result set, that is the record count of the result set.
one solution to that is to first use the executeUpdate and then use the executeQuery but i think that is not the right way.
so please tell me is there any method in jdbc to get that thing done

Hi
Do you know if your DB supports "insensitive scrolling"?
SQL generally do, but some don't - I had the same problem with the
open source version of Interbase from Phoenix...
Anyway - try creating your statement this way:
public Statement createStatement(int resultSetType, int resultSetConcurrency)
throws SQLException
...where resultset type should be:
ResultSet.TYPE_SCROLL_INSENSITIVE
Then you can do this:
ResultSet rs = stm.executeQuery(q);
int size = rs.last(); //this what you looking for?
rs.beforeFirst();
while(rs.next()){
}
