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
