如何用聚合函數sql server選擇列

Question

我需要選擇兩列。 計算一列的總和並顯示它2.顯示列。 所以我嘗試下面的代碼

SELECT Sum(CONVERT(FLOAT, Replace(total, Char(0), ''))) AS Total, 
       [product name] 
FROM   tb_sales_entry_each_product 
GROUP  BY [sales date] 

錯誤信息

Column 'tb_sales_entry_each_product.Product Name' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause.

我犯了什么錯誤。謝謝

Answer 1

嘗試這個：

select SUM(CONVERT(float, REPLACE(Total, CHAR(0), ''))) as Total, 
[Product Name]  ,[Sales Date]
from tb_sales_entry_each_product 
group by [Sales Date],[Product Name]

Answer 2

只需要分組

select SUM(CONVERT(float, REPLACE(Total, CHAR(0), ''))) as Total, [Product Name]  
from tb_sales_entry_each_product group by [Sales Date], [product name]

如果您進行了商業計數總和等，則需要對任何其他列進行分組。 這就是你所有的遺失
