Since you usually need to know the total number of
rows a query would return, do you think it's better
to:

a) Do one query with a LIMIT and OFFSET to get the
results, and another COUNT query to get the total
number of rows?

b) Do a single query without a LIMIT and OFFSET, then
do a seek or similiar to get at the rows you want?

Most tutorials, code, etc. I've seen do "a". The
eclipse library does "b".
