MySQL查询性能问题与MyISAM表

Question

民间

我有一个表（billing_data）与约6000万条记录。表引擎是MyISAM。我们有一个存储过程，它将读取csv文件并每10-15分钟转储到临时表中，然后将其插入此表（billing_data）中。这个表格中插入了很多记录。

我们正试图在同一张表（加上联接中的其他表）上运行查询以生成报表。

"select b.destination,b.release_cause_protocol_stack,b.binary_value_protocol_stack,b.release_cause from billing_datas b inner join (select id from carriermasters where id in (99, 100, 101)) c1 on b.carrierid_customer=c1.idinner join (select id from technicalprofiles where id in (83, 274, 84, 416)) t1 on b.technical_profileid_customer=t1.id inner join (select trunk from trunks where trunk in (90409, 90310, 30230, 30313)) tr1 on b.origination_trunkid=tr1.trunk inner join (select id from carriermasters where id in (214, 215, 59, 60, 62, 292, 63, 216, 64, 61, 217, 274, 58)) c2 on b.carrierid_supplier=c2.id inner join (select id from technicalprofiles where id in (223, 55, 224, 56, 225, 57, 226, 58, 227, 228, 229, 230, 393, 394, 395, 59, 231, 232, 233, 460, 234)) t2 on b.technical_profileid_supplier=t2.id inner join (select trunk from trunks where trunk in (90106, 30249, 90249, 30250, 90250, 90445, 30409, 90446, 30410, 30294, 90363, 30293, 90293, 30175, 30146, 90146, 90435, 90049, 30177, 90294, 90130, 30130, 90189, 30145, 90145, 90389, 30400, 90429, 90121, 90159)) tr2 on b.supplierid=tr2.trunk where b.start_time_date between '2013-08-02 00:00:00' and '2013-08-02 23:59:59' order by b.start_time_date asc" 

现在的情况是

一）如果我们停止cron作业在billing_datas表中插入数据，然后将上面的查询大约需要40多分钟。 b）如果cron作业正在运行（从文件中插入数据）到临时表，然后到billing_data。那时上面的查询将永远运行。

我不知道我在哪里出错。

我们还检查了索引和罚款。
