每个表格的总和和个人表格的总和

Question

我有两个表格，我想查找两个表格记录的总和以及每个表格的总和。这里是我的查询，它给了我两个正确的总和。

select sum(tot_live) as tot_live 
     from (select count(id) as tot_live from crm_rentals where status = 2 and is_active=1 and is_archive=0 
     union 
     select count(id) as tot_live from crm_sales where status = 2 and is_active=1 and is_archive=0) s 

这给我tot_live = 300

现在我想告诉每一个像300 = 100和200

tot_live | table1 |table2 
300  100  200 

Answer 1

尝试somethine像下面的计数：

select @table1:=(select count(id) as tot_live from crm_rentals where status = 2 and is_active=1 and is_archive=0), 
@table2:=(select count(id) as tot_live from crm_sales where status = 2 and is_active=1 and is_archive=0), 
(@table1 +@table2) as tot_live
