ORACLE 视图合并SQL优化案例
朋友给了一条SQL说跑8个小时才出结果，结果集很小75条数据，给他安排一下。
SQL如下：

可以通过A-Time看到17s结果已经出来了。
为什么原来的SQL需要跑8小时才能出结果，而加一条 HINT /*+MERGE(T)*/ 17s 就能跑出来，因为这条 HINT 让 from 后面的（内联视图/视图）合并了，CBO 会尝试将内联视图/视图拆开，进行等价的改写，这个过程就叫作视图合并。
更详细的内容可以百度：ORACLE 视图合并，这里就不过多赘述。
想交流 SQL调优、PLSQL、SQL等价改写、JAVA 的朋友可以联系我 18902234014（微信同号），相互学习，共同进步。
