获取百分比复杂查询雅典娜

Question

我已经做了一个复杂的查询来获取多个值。然后显示第二个参数占总数的百分比。

我必须对大量变量执行此操作。

基本上：

1. 联合行从两个表中计数以获得总计。
2. 将两行计数与已应用的参数合并。
3. Parametercount / grandtotal =百分比

我必须对大约6个参数执行此操作。

select
sum(givesmeonesubset_1) as grandtotal
(
Select

count(*) as givesmeonesubset_1

from 

table1

union all

Select

count(*) as givesmeonesubset_2

from 

table2
)

union all
select
sum(givesmeonesubset_param) as subtotalparam
(
Select

count(*) as

from 

table1
where param ='x'
union all

Select

count(*) as givesmeonesubset_2

from 

table2
where param ='x'

)
