这个查找语句怎么写？[之前发过一个但是我想错了]



我想查看的这3个是 SceneId，UsersSex = '男'的用户人数，UsersSex = '女'的用户人数。

补充说明一下UsersName是UsersInfo主键，还是ApplyInfo外键。SceneId是ApplyInfo外键

之前发过一个了 = = 求各位大神帮忙

[解决办法]
try

SQL code

select b.SceneId,  男用户人数=sum(case when a.UsersSex='男' then 1 else 0 end),  女用户人数=sum(case when a.UsersSex='女' then 1 else 0 end)from (select distinct SceneId,username from applyinfo) bjoin usersinfo a on a.a.username=b.usernamegroup by b.SceneId
