how to count size of resultset in OJB

[Zhou, Andrew]

Hi guys,
 
I guess this question has been asked by many people. 
 
Basically, I'd like get the count(*) from query, that way, I can give
user an option if or not user want retrieve everything back.
 
I am wondering if there is any dicussion on this topic before. I'd
really appreciate if anyone can give some advice.
 
Thanks
