场景：
希望使用phoenix做查询服务，给服务端提供接口
设计：
通过springboot做restful的接口发布，通过mybatis做phoenix的sql处理，因此是springboot+mybatis+phoenix的集成方案；
但是会遇到一个坑!
=========================================我是华丽的分割线=====================================================
先简单汇报下场景：
做网约车的预约单查询处理，如图：
这里面需要使用一个时间窗口查询6种时间：推送订单时间、有效抢单时间、抢单成功时间、取消订单时间、达到目的地时间、支付时间
这里可能遇到一个问题：跨天支付！
因此为了解决跨天支付，需要在处理好的基表基础上做6次查询 ，分别对应不同的查询时间，然后做union处理，最后在求和（注意：就是在最后在求和的地方出错!!!!!）
先看下有问题的代码：

这段代码大概就是：
select tb."driver_id" ... , sum(xxx1) , sum(xxx2) , ..... from ( A union B union C union D union E union F union G ) as tb group by tb."driver_id" ...
这种操作的问题就在于：使用mybatis做union后，生成了一张表tb ， 按照phoenix的官方说法是，phoenix严格区别大小写的，因此我们做完phoenix后，习惯性的在字段上加上双引号；
但是如果是使用mybatis做了集成后，union生成的表名称和字段名称，是不需要也不能在区分大小写的，因此在加双引号，就会出现字段找不到等一系列错误
解决后的代码：
