我想对UpazillaID在1,2中求和CityArea，VillageArea，CharArea，HillArea，HaorArea，TotalArea。

Answer 1

选择（column1 + column2 + column3 ....）作为总列。 这将为您提供每行的总和。

Answer 2

SELECT (SUM(CityArea)+SUM(VillageArea)+SUM(CharArea)+SUM(CharArea)+SUM(CharArea)+SUM(TotalArea)) 
AS Total
FROM your_table
WHERE UpazillaID = 1
