只返回一条数据 Success, cost 11 second(s)663 millsecond(s). 执行时间 11秒左右。
平时简单的SQL基本不用看执行计划大概都能知道哪里慢的，但是像这种看着是挺复杂的，也不知道慢在哪，DM执行计划就算难看也要分析了。🤣
从 DM 的 ET 工具可以看到本条SQL最慢的在 152行，SSCN 占了 整条SQL 60%的时间，对应执行计划中 #SSCN: [793, 6385120, 48]; TAWC_STATIC_RESULT_BASEDATE(TAWC11111)
SSCN 是什么意思各位读者同学感兴趣的可以自己去 DM 官网查查，反正我不知道，但是我知道哪里慢，下面这段很慢，要 11秒。

看到现在应该会有杠精同学问我，那这里为什么会慢？是不是写SQL的研发太垃圾了？还是DM数据库太垃圾了？
可以明确回答，因为我看不懂 DM 的执行计划所以不知道上面为什么慢，不知道CBO做了什么查询转换这些动作。
但是可以明确的是，写SQL开发不垃圾，能写出这么复杂的统计SQL也是很厉害的。
但是DM确实有点拉胯，执行计划让人看不懂这就说不过去了，DM的执行计划是我目前遇到数据库中最难看懂的计划，就像上面的SQL，想分析些CBO做了什么查询转换都分析不了，因为看不懂，只能靠猜。

优化前后比较：
可以看到随便搞了一下，原来 11.6秒出结果的，现在 1.6 秒就能跑出结果了。😎😎
其实还能帮任总老婆优化得更快点，但是任总太小气了，饭都不请我吃一顿，差不多这样行了。😼😼😼
