创建合理的索引避免order by操作提升SQL性能的案例一

某医保系统的查询一年内一个中心所有医疗费登账记录的汇总情况执行3000多秒才能出结果,下面TOP SQL中执行时间最长的SQL语句它的功能是查询一年内一个中心所有医疗费登账记录的汇总情况,执行时间3286秒,则且这条SQL就是我们要找的SQL语句。

从其执行计划中可以看到最消耗成本的操作就是对IDX_PM_ACCOUNT_BIZ_SERIAL_DATE索引执行索引范围扫描返回285K条记录再回表查询记录的成本是56867,而整个SQL语句的成本是56871。再与BS_CENTER表执行排序合并连接,再与MT_BIZ_FIN执行嵌套循环连接,再执行group by操作。因为表BS_CENTER表只有10几条记录,且表中的center_id是主键,表PM_ACCOUNT_BIZ中center_id与其它列存在复合索引,理想的执行计划应该是先访问表BS_CENTER再与PM_ACCOUNT_BIZ表执行嵌套循环连接,再与MT_BIZ_FIN连接。而且上述SQL中的group by子句是可以去掉了,这里group by真正的作用只起到了去掉重复记录的作用,而PM_ACCOUNT_BIZ表的主键是account_id,在查询列中,所以可以去掉这个group by 子句。

上面的SQL语句简化如下形式:

select ...省略
from pm_account_biz a
         where 1 = 1
           and ('0' = 'A' or a.reimburse_flag ='0')
           and ('00' = '00' or a.biz_type ='00')
           and a.center_id in ('430722')
           and (a.fin_date between to_date('2014-01-01 00:00:00', 'yyyy-mm-dd hh24:mi:ss') and

其执行计划中现在是选访问表BS_CENTER后再与PM_ACCOUNT_BIZ执行嵌套循环连接,与我们设想的一样,这里慢的主要原因是因为要对表连接之后的记录执行order by a.hospital_id, a.serial_no操作。PM_ACCOUNT_BIZ表的查询条件中有and a.center_id in (‘430701’) and (a.fin_date between to_date(‘2014-01-01 00:00:00’, ‘yyyy-mm-dd hh24:mi:ss’) and
to_date(‘2014-12-31 23:59:59’, ‘yyyy-mm-dd hh24:mi:ss’)),而在CENTER_ID与FIN_DATE列上有存在复合索引。索引信息如下所示,在创建索引时,索引列的记录默认是按升序来存储的,而查询中要进行升序操作的列就是hospital_id,serial_no,而这两列已经存在复合索引IDX_PM_ACCOUNT_BIZ_SERIAL_NO中,而该索引中首列是CENTER_ID,我们只要把fin_date列加入这个复合索引中就可以让CBO在执行查询时使用该索引且能避免排序操作,而在IDX_PM_ACCOUNT_BIZ_SERIAL_DATE索引的有两列分别是CENTER_ID与FIN_DATE所以可以将这两个索引合并成一个新的索引(create index idx_pm_account_biz_center_id on pm_account_biz(center_id,hospital_id,serial_no,fin_date),并删除原先的这两个索引。

从上面的实际执行情况可以看到返回了接近19万条记录花费的时间是1分37秒,也就是97秒与3286秒,已经是几十倍的提升了。

小结:这里优化的方法是通过修改SQL语句,改变表连接的方法,去掉不必要的分组(group by)操作,创建来合理的复合索引来避免排序(order by)来达到性能的提升。
