如何選擇具有聚合函數sql server的列

Question

我需要選擇兩列。計算一列的總和並按原樣顯示它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. 

在那裏我做error.thanks

Answer 1

剛需羣體

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

當你做一個商業計數總和等，任何其他列需要分組。 多數民衆贊成多數民衆贊成在多數民衆贊成你就錯過了

試試這個：

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]
