求解啊？

姐姐搞错了，修改的不是你的原版的，不过也是一样的

SUM(d1) AS d1,
SUM(d2) AS d2 就可以了

SQL code
SELECT name,  AVG(a) as a,  AVG(b) as b,  AVG(c) as c,SUM(CASE WHEN d<5 THEN 1 ELSE 0 END) * 100.0 / COUNT(d) AS d1,SUM(CASE WHEN d>=5 THEN 1 ELSE 0 END) * 100.0 / COUNT(d) AS d2FROM [ta]GROUP BY [name]having AVG(a)<=6UNION ALLSELECT '统计',  AVG(a) as a,  AVG(b) as b,  AVG(c) as c,SUM(d1) AS d1,SUM(d2) AS d2FROM  (    SELECT [name],      AVG(a) as a,      AVG(b) as b,      AVG(c) as c,    SUM(CASE WHEN d<5 THEN 1 ELSE 0 END) * 100.0 / COUNT(d) AS d1,    SUM(CASE WHEN d>=5 THEN 1 ELSE 0 END) * 100.0 / COUNT(d) AS d2    FROM [ta]    GROUP BY [name]    having AVG(a)<=6) ta
