Question

我想结合lightcount和TotalLightCount的总和例如，如果lightcount = 100且TotalLightCount = 300，则最终总和将为400.这是我到目前为止的代码，但是我得到两笔金额而不是合计金额。

<%  
Set rstest = Server.CreateObject("ADODB.Recordset")
sql = "SELECT SUM(count) AS TotalCount, SELECT SUM(lightcount) AS TotalLightCount FROM Records;" 
rstest.Open sql, db
%>

Answer 1

你在找这个吗？

SELECT SUM(count) + SUM(lightcount) AS GrandTotal 
  FROM Records;

或

SELECT SUM(count) AS TotalCount, 
       SUM(lightcount) AS TotalLightCount,
       SUM(count) + SUM(lightcount) AS GrandTotal 
  FROM Records;

如果您需要结果集中的所有三列

Answer 2

我认为这会对你有帮助，

SELECT column1, column2, (column1+column2) AS SumColumn FROM Table1

Answer 3

<%  
Set rstest = Server.CreateObject("ADODB.Recordset")
sql = "SELECT SUM(count) + SELECT SUM(lightcount) AS TotalLightCount FROM Records;" 
rstest.Open sql, db
%>

我需要在SQL中组合一个总和
