我有这三张桌子

tbl_1-
ip  |isp    |infection
----------------------
1   |aaaa   |malware
2   |bbbb   |malware
3   |cccc   |ddos
3   |cccc   |trojan
4   |dddd   |ddos

tbl_2-
ip  |isp    |infection
----------------------
1   |aaaa   |malware
3   |cccc   |ddos
4   |dddd   |trojan
5   |eeee   |trojan
6   |ffff   |other

tbl_3-
ip  |isp    |infection
----------------------
1   |aaaa   |ddos
6   |ffff   |
2   |bbbb   |other

我需要得到如下结果，

result-
ip  |isp    |infection  |ipCount    |ispCount   |infectionCount
--------------------------------------------------------------
1   |aaaa   |malware    |3          |3          |2
1   |aaaa   |ddos       |3          |3          |1
2   |bbbb   |other      |2          |2          |1
2   |bbbb   |malware    |2          |2          |1
3   |cccc   |ddos       |3          |3          |2
3   |cccc   |trojan     |3          |3          |1
4   |dddd   |ddos       |2          |2          |1
4   |dddd   |trojan     |2          |2          |1
5   |eeee   |trojan     |1          |1          |1
6   |ffff   |other      |2          |2          |1
6   |ffff   |           |2          |2          |1

ipCount, ispCount -> count of matching ip and isp
    eg-there are 3 records with ip = 1 and isp = aaaa

infectionCount -> count of matching infections per ip and isp
    eg-there are 2 infections that says malware where ip = 1 and isp = aaaa

我想我需要一个嵌套查询，但是我不知道如何在两个条件下进行计数。你能帮我吗？

编辑 ：我尝试过的代码，

SELECT ip, isp, infection, count(ip), count(isp), count(infection)
FROM (

SELECT ip, isp, infection
FROM tbl_1
UNION ALL
SELECT ip, isp, infectionType
FROM tbl_2
UNION ALL
SELECT ip, isp, infection
FROM tbl_3
)x

GROUP BY ip, isp, infection

但这并没有给出我想要的结果，因为我不知道如何在一个查询中进行两种类型的计数
