我想基于某些字段进行查询以生成报告：日期范围，部门，具有日期范围的学生。我有用于搜索的表单......
但是，我需要从报告中计算每个字段的总计。 例如：如果我搜索学生并且搜索结果是：
DeptA 1/1 / 2012-12 / 31/2012 StuA $ 100 DeptA 1/1 / 2012-12 / 31/2012 StuB $ 50 DeptA 1/1 / 2012-12 / 31/2012 StuC $ 50
如何在线自动计算总费用（= $ 200）？ 感谢。
这是我的代码：
<%

While (Right(Path, 1) <> "\" And Len(Path) <> 0)
iLen = Len(Path) - 1
Path = Left(Path, iLen)

adoCon.open strCon
SelectStmt = "Select * From view_costs Where "
WhereClause = ""
WhereBetweenClause = "BETWEEN"
If Request("qryDepartment") <> "All Departments" Then
qryDepartment = replace(request("qryDepartment"),"'","''")
WhereClause = WhereClause & "Department = '" & qryDepartment & "' AND "
End If
If Request("qryStudents") <> "All Students" Then
WhereClause = WhereClause & "Name = '" & Request("qryStudents") & "' AND "
End If
sStartDate = Request("StartDate")

WhereClause = WhereClause & "(StartDate >= '" & sStartDate & "' AND EndDate <= '" & sEndDate & "') "
End If

答案 0 :(得分：0)
为什么不在SQL中指定字段（而不是“SELECT * ...”），然后通过循环中的变量将值相加，并在循环后将它们输出到新的表格行中？
或者您可以使用SQLs SUM（）函数来查询这些值。
