Reporting services 如何连接两个参数的值？（Visual Studio报告2008）

我在VisualStudioReports2008中有一个报告。 我的报表包含数据源2，每个数据源都有参数

如何连接两个参数的值

例如： 参数1、参数值2的值

Group1,Class1

Group2, Class1

Group3, Class1

Group4, Class2

Group5, Class2

Group6, Class2

Group7, Class2

Group8, Class2

Group9, Class3

Group10, Class3

Group11, Class3

Group12, Class3

Group13, Class3

我创建了3个参数并添加了以下函数（在参数属性-可用值-选择指定值-添加函数中）：

可以使用表达式根据参数1为参数2设置确定的值

如果参数1允许多个值选择，则可以使用

IndexOf

函数。在“参数2属性”的“默认值”选项卡中，选择“指定值”并添加新表达式，使用以下选项：

=Switch(
Array.IndexOf(Parameters!MyParam1.Value,"Group1")>-1,"Class1",
Array.IndexOf(Parameters!MyParam1.Value,"Group2")>-1,"Class1",
Array.IndexOf(Parameters!MyParam1.Value,"Group3")>-1,"Class1",
Array.IndexOf(Parameters!MyParam1.Value,"Group4")>-1,"Class2",
Array.IndexOf(Parameters!MyParam1.Value,"Group5")>-1,"Class2",
Array.IndexOf(Parameters!MyParam1.Value,"Group6")>-1,"Class2",
Array.IndexOf(Parameters!MyParam1.Value,"Group7")>-1,"Class2",
Array.IndexOf(Parameters!MyParam1.Value,"Group8")>-1,"Class2",
Array.IndexOf(Parameters!MyParam1.Value,"Group9")>-1,"Class3",
Array.IndexOf(Parameters!MyParam1.Value,"Group10")>-1,"Class3",
Array.IndexOf(Parameters!MyParam1.Value,"Group11")>-1,"Class3",
Array.IndexOf(Parameters!MyParam1.Value,"Group12")>-1,"Class3",
Array.IndexOf(Parameters!MyParam1.Value,"Group13")>-1,"Class3"
) 

否则，如果您的参数不允许多个值，您只需使用：

=Switch(
Parameters!MyParam1.Value = "Group1","Class1",
Parameters!MyParam1.Value = "Group2","Class1",
Parameters!MyParam1.Value = "Group3"1,"Class1",
Parameters!MyParam1.Value = "Group4","Class2",
Parameters!MyParam1.Value = "Group5","Class2",
Parameters!MyParam1.Value = "Group6","Class2",
Parameters!MyParam1.Value = "Group7","Class2",
Parameters!MyParam1.Value = "Group8","Class2",
Parameters!MyParam1.Value = "Group9","Class3",
Parameters!MyParam1.Value = "Group10","Class3",
Parameters!MyParam1.Value = "Group11","Class3",
Parameters!MyParam1.Value = "Group12","Class3",
Parameters!MyParam1.Value = "Group13","Class3"
)

我建议您将参数2设置为隐藏，以避免 用户手动更改参数的值

让我知道这是否有帮助。

参数1和2允许多个值选择

使用新表达式和选择参数值会显示错误： “本地报表处理中出错。参数2”
