how does valentina use aliases? The previous example I
dont necessarily need them but im sure my other sql
string requires it:

select wstr_id, wstr_number, wstr_title,
(ai.wwri_count)/ length(wstf_fulltext)*1000 as
wstr_score from wstr, wwri as ai, wwrd as a, wstf
where (wstr_id = ai.wwri_wstr_id) and (ai.wwri_wwrd_id
= a.wwrd_id) and wstf_wstr_id = wstr_id and
(a.wwrd_word = 'biology'  ) order by wstr_score desc"

do you now how would I write this for valentina?

Thank you for your help

Fiona
