If you want to count how many rows are in result set, I dont think you can, but you could always run a count statement for that sql
say your sql is
select field1, field2, field3
from table1, table2
where field4=field5 ......
then you can count the rows this statement returns by
select count(*) from
(say your sql is
select field1, field2, field3
from table1, table2
where field4=field5 ......)
This way you will get the count for just that sql
