sql查询总结

这周的任务有一项是做数据统计

统计内容如下：

一张表中的会议类型有党小组会议、党员大会、党委会议、区划字段

要求：统计出每种区划下的每种会议类型的正常开展、逾期开展、逾期未开展

我设想的思路：先把每个区划查询出来并去重复　　

　　　　　　　然后把每个区划下的各种会议总数统计出来

　　　　　　　然后在查询每种会议的正常开展、会议逾期开展的在用每种会议的总数减去正常开展、会议逾期的个数

　　　　　　　这样构建一条数据传到前台显示就相当于下面图文中的数据样式

实现这种样式我用的是mvc+mybatis，下面我们上代码前台的就不显示都是差不多一样的你们改下变量就差不多了

接口就不上了都差不多

开始做的时候有点懵，后来慢慢理了下思路找到这么个笨方法如何有更好的办法。各位大佬请指出来我也借鉴下。
