在多个列的选择总和1列

Question

我试图sum（）我的选择查询按日期值分组它们的数量字段，但Sql不断给我的错误，说没有AL列分组在我的GroupBy，但我只想O基团并按照时间

这是我的查询：

SELECT Date, Clave_PDV, Che, Lin, Dish, Dish_Name, Type, 
sum(Quantity) as Quant, Price, Total, Tur, Tur_Name, Group, 
Group_Name, Pdv_Name, St_Pla, St_Che 
FROM Dish_Sales 
GROUP BY Date 

我怎么能总和（数量）的日期将它们分组？

Answer 1

你会删除所有你不想要的列：

SELECT Date, sum(Quantity) as Quant 
FROM Dish_Sales 
GROUP BY Date; 

Answer 2

如果你想通过日期之应我们发

SELECT Date, sum(Quantity) as Quant 
FROM Dish_Sales 
GROUP BY Date 

否则，你应该为所有列使用该组未汇总

SELECT Date, Clave_PDV, Che, Lin, Dish, Dish_Name, Type, 
sum(Quantity) as Quant, Price, Total, Tur, Tur_Name, Group, 
Group_Name, Pdv_Name, St_Pla, St_Che 
FROM Dish_Sales 
GROUP BY Date, Clave_PDV, Che, Lin, Dish, Dish_Name, Type, 
    Price, Total, Tur, Tur_Name, Group, 
     Group_Name, Pdv_Name, St_Pla, St_Che
