基本上我需要获得一份在StaffOnGrade中出现超过2次的CampaignTitles列表,并列出等级等级高于2的CampaignTitle,StaffNo
WorksOn表:
CampaignTitle | StaffNo
-------------------|--------
ADVENTURE WORLD | 11
AIR CANADA | 11
CARNIVAL CRUISES | 3
CARNIVAL CRUISES | 8
CARNIVAL CRUISES | 9
FLIGHT CENTRE | 7
FLIGHT CENTRE | 10
HARVEYWORLD TRAVEL | 4
LAST MINUTE | 4
PRINCESS CRUISES | 3
PRINCESS CRUISES | 5
PRINCESS CRUISES | 6
PRINCESS CRUISES | 7
PRINCESS CRUISES | 11
TRAVELSCENE | 10
VALUETOURS AUST | 3
VIRGIN AUSTRALIA | 10
StaffOnGrade表:
Grade | StaffNo
------|--------
1 | 2
2 | 11
3 | 3
3 | 6
3 | 7
4 | 4
4 | 8
4 | 10
5 | 5
5 | 9
以下两个查询实现了各个部分,但我需要将其作为一组查询结果返回。
SELECT campaigntitle, COUNT (CAMPAIGNTITLE) As [count]
FROM WORKSON
GROUP BY CAMPAIGNTITLE
HAVING COUNT(CAMPAIGNTITLE) >2
SELECT STAFFNO, GRADE
FROM STAFFONGRADE
WHERE GRADE > 2
希望这是有道理的!
答案 0 :(得分:6)
SELECT campaigntitle, StaffNo, COUNT (CAMPAIGNTITLE) As [count]
FROM WORKSON
WHERE StaffNo IN
(SELECT STAFFNO
FROM STAFFONGRADE
WHERE GRADE > 2)
GROUP BY CAMPAIGNTITLE
HAVING COUNT(CAMPAIGNTITLE) >2
