自定义函数导致的sql性能问题

同事说，某某报表跑的很慢，让我调查一下

优化前：该报表整体需要跑4小时以上。

sql代码如下

分析步骤

• 确认性能瓶颈

抓取到以上sql后，首先拿到测试环境运行，发现如下问题，能在20分钟内出结果，但是要刷出全部结果，却需要 >2h
分析sql，发现其查询字段中，带有很多自定义函数 rep_fun，去掉分析函数，sql能在1分内刷出全部结果。
由此可以确定该sql的性能问题，出在自定义函数上。

• 分析自定义函数

单独运行函数中select语句，发现其的访问路径为“全表扫描”，且分组函数是MAX，所以可以在（policyno，ENDORSEMENTNO）上建立组合索引。
