I am making a connection to a remote data table. 9 times out of ten I expect to return more than one record. To get my result I use the while(rs.next()) function. But how do I check to see if there are no records returned. In situations where only one record is expected I use if(rs.next()) which works great. How do I handle the empty while condition?

If we don't do the shopping, we won't have anything for dinner. And I've invited this tiny ad:
