MySql SELECT query not working after INSERT query -

i have table next structure:

create table emp ( id int( 11 ) not null auto_increment, fname varchar( 20 ) character set latin1 collate latin1_swedish_ci null , lname varchar( 20 ) character set latin1 collate latin1_swedish_ci null , category varchar( 20 ) character set latin1 collate latin1_swedish_ci null , primary key (id) );

i first inserted null values table. inserted 3-4 records (used auto increment).

there huge select query in bring together table 7 other tables. when run select query 1 null record in table, query works. if run select query after inserting few values in above table, select query hangs , consuming whole lot of cpu. cause?? please help.

my query

select * g, id, j, epm, isg, des, eng, pace, mal, msa, u, sa, db, qa, s, mk, p, sre, sec, t t.st = 'open' , t.id = j.pid , t.g_id = g.gid , t.pu_id = id.puid , t.a_id = epm.aid , t.i_id = isg.iid , t.d_id = des.did , t.e_id = eng.eid , t.pace_id = pace.paceid , t.m_id = mal.mid , t.sa_id = msa.said , t.u_id = u.uid , t.s_id = sa.sid , t.dba_id = db.dbaid , t.qa_id = qa.qaid , t.sup_id = s.supid , t.mkt_id = mk.mktid , t.pan_id = p.panid , t.sec_id = sec.secid , t.sre_id = sre.sreid order g.name;

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...
