php - Joining Three Tables -

i'm trying take info 3 different tables , output using few queries , little php code possible.

listed below tables have , columns in each (only listing relevant columns).

exp_members (a) columns: member_id, group_id

exp_brandrelations (b) columns: member_id, brand_id

exp_du_mktgmats (c) columns: du_id, brand_id, date

i want loop through members belong group_id='5' (from a), determine brands assigned each fellow member (from b), , list of du_ids (from c) correspond each member, have been inserted in lastly 24 hours.

so far, can list of members in grouping 5: select member_id, brand_id exp_brandrelations where member_id in (select member_id exp_members group_id = 5)

and can list of du_ids lastly 24 hours: select du_id exp_du_mktgmats where date >= date_sub(now(), interval 1 day)

but i'm not sure how best tie together.

this should it!

select m.member_id, b.brand_id, d.du_id exp_members m, exp_brandrelations b, exp_du_mktgmats d m.group_id = '5' , m.member_id = b.member_id , b.brand_id = d.brand_id , d.date >= date_sub(now(), interval 1 day)

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
