Question

Linetotal tax taxsum 
-------------------- 
1150  Bed 250 
1150  HSC 150 
1150  CESS 110 

我想總的taxsum（250 + 150 + 110）和linetotal（1150）的總和= 1660

這能在SQL Server使用T完成-SQL查詢？

Answer 1

Select sum(taxsum) + avg(linetotal) 
From yourtable 

Answer 2

這是語法，你想用

SELECT SUM(column_name) FROM table_name; 

您的代碼可以作爲（假設你的表名是GetTheSum）

SELECT SUM(taxsum) AS TAXTOTAL FROM GetTheSum; 

最終的答案：

SELECT (Linetotal + taxsum) AS TOTAL FROM GetTheSum 

Answer 3

Try：

SELECT SUM(taxsum) AS Taxes, SUM(LineTotal) + SUM(taxsum) AS Total 
FROM mytable 
GROUP BY LineTotal 

Answer 4

你可以用子查詢來做到這一點。

SELECT Linetotal + s FROM (
    SELECT Linetotal, sum(taxsum) s FROM table_name GROUP BY Linetotal 
) a 

或者只是

SELECT Linetotal + sum(taxsum) AS total FROM table_name GROUP BY Linetotal 

注：問題是有點不清楚。我假設你想爲每個Linetotal總計taxsum，並將Linetotal添加一次。
