优化笔记:jsyhjkzqxx_D_20140916.gz

有几张表没有权限,所以跑不起来。

 

目测黄色部分比较坑爹,死了n多脑细胞才看懂,又死了n多脑细胞才改出来。对5034进行了2次扫描,并多次分组排序求和。(分组和排序算法相对来说比较耗性能)

 

改为只扫描一次,一次编号操作。

 

 

 

这个没有什么既定的规则,就是使劲想各种奇葩办法简化。(这个改写就是利用了oracle在排序的时候,把null当成无穷大。而在sqlserver上就不适用了,因为sqlserver在排序的时候把null当无穷小)

 

 

 

黄色部分可改为下面的代码。

 

 

 

select *

 

  FROM (select f1_5034,

 

               decode(min(rn_a) - 1, 1, 0, min(rn_a) - 1) ylqk,

 

               min(rn_b) - 1 bbqk

 

          from (select case

 

                         when nvl(f25_5034, 0) > 0 then null

 

                         else rn end rn_a,

 

                       case

 

                         when f25_5034 Is not Null then null

 

                         else rn end rn_b,

 

                       f1_5034

 

                  from (Select f1_5034,

 

                               f3_5034,

 

                               f25_5034,

                          From wind.tb_object_5034

 

                         Where f3_5034 Like '%1231'))

 

         group by f1_5034)
