现有2个查询，需要将每个查询的结果合并起来(注意不是合并结果集，因此不能使用union）,可以将每个查询的结果作为临时表，然后再从临时表中select所需的列，示例如下：

 

SELECT get.daytime, get.data as get, xh.data as xh         FROM (                 SELECT daytime, sum(get_sum) as data                 FROM yuanbao_get                 group by daytime                 order by daytime         ) as get,         (                 SELECT daytime, sum(xh_sum) as data                 FROM yuanbao_xh                 group by daytime                 order by daytime         ) as xh         where get.daytime = xh.daytime
