推荐答案

由于您没有给我们任何信息，所以您的数据库表中的列是什么意思，也没有提到表的名称，我"会有点在黑暗​​中摸索":

Since you have not given us any information what the columns in your database table mean and neither have mentioned the table''s name, I''ll be "groping around in the dark" a bit:

SELECT OName, SUM([Area(ha)] AS TotalArea
FROM SomeTableName
GROUP BY OName

如果一个人的名字不只是OName，则必须调整 GROUPBY [ select语句的 ^ ]子句.

问候，

曼弗雷德(Manfred)

In case the name of a person is not just OName, you''d have to adjust the GROUPBY[^] clause of the select statement.

Manfred
