Greetings All

I have two tables, ab.comp_results and ab.competitions. I want to
execute a select query and JOIN these two tables. This is easy enough
but, here is my problem.

QUERY:
SELECT CR.pos, CR.member_name, CR.comp_img, CR.competition, C.town,
C.comp_name, C.comp_date FROM ab_comp_results CR, ab_competitions C " +
"WHERE cup = '" + request.getParameter("cup") + "' AND CR.competition =
'" + request.getParameter("comp") + "' AND sex = 'Female'";

Seeing that CR.competition has to first match the requestParameter, how
do I go about JOINing these two tables ON CR.competition and C.comp_name
based on the value of request.getParameter("comp")? The reason I want to
JOIN these two tables is so that I do not have to duplicate the town and
comp_date values inside of the ab.comp_results table.

Any help, ideas or pointers are welcome. Thanks!
