是否可以使用交叉查询来执行此操作? (在Access 2007中)
我有这张桌子:
50 | A1
60 | A1
70 | B1
80 | B1
90 | C1
我需要得到这个结果:
A1 ------------------ B1 --------------- C1
总和|平均-----总和|平均-----总和|平均
55 | 110 --------- 75 | 130 ------ 90 | 90
我试着怀疑这个:
TRANSFORM Sum(Worki.Value) AS XXsum
SELECT Worki.Name AS Name, Worki.Tdate AS Tdate, Worki.ID AS ID
FROM Worki
GROUP BY Worki.Name, Worki.Tdate, Worki.ID
PIVOT Worki.Trit;
我如何获得平均值和总和?
答案 0 :(得分:1)
尝试
select sum(colname),avvg(colname) from tablename group by colname
