我有以下表结构也有我提到我的预期输出，请帮我查询按我刚才的问题
获取计数使用组由SQL多个字段
我得到的输出使用下面的查询如下
select data.category, cl.combovalue as esilocation, cd.combovalue as esidispensary,
year(date) as year, month(date) as month,
sum(data.joins) as [Joining Count], sum(data.terms) as [Termination Count]
from (
select category, esilocation, esidispensary, dateofjoining as date,
1 as joins, 0 as terms
from dbo.employeedetail
where dateofjoining is not null
union all
select category, esilocation, esidispensary, terminationdate as date,
0 as joins, 1 as terms
from dbo.employeedetail
where terminationdate is not null
) data
left join dbo.combovalues cl on cl.id = data.esilocation
left join dbo.combovalues cd on cd.id = data.esidispensary
where category in ( 1, 2 )
and date >= '2014-01-01'
and date <= '2014-12-31'
group by data.category, cl.combovalue, cd.combovalue, year(date), month(date)
查询输出：
category esilocation esidispensary year month Joining Count Termination Count
1 mumbai mumbai 2014 8 1 0
1 mumbai mumbai 2014 11 0 1
1 pune mumbai 2014 6 1 0
1 pune mumbai 2014 8 1 1
2 pune mumbai 2014 10 1 0
2 pune mumbai 2014 11 0 1
2 pune pune 2014 9 2 0
2 pune pune 2014 11 0 2
但问题是，我想这上面的表格，即枢纽
预计输出
category esilocation esidispensary 8/2014 join 8/2014 term 11/2014 join 11/2014 term
1 mumbai mumbai 1 0 0 1
1 pune mumbai 1 1 null null
2 pune mumbai null null 0 1
2 pune pune null null 0 2
