以编程方式添加Adomd参数C#

下午全部。

我正在构建一个Web应用程序,我正在尝试从SSAS多维数据集中提取一些数据。

我有以下MDX我希望在c#中复制,但添加了一些参数,即两个参数,一个用于公司123,另一个用于位置1:

@"SELECT NON EMPTY([Dim Unit].[All Units].[Category Group Name]) ON COLUMNS
                    FROM [Info]
                    WHERE ([Dim Company].[All Companies].&[123], 
                    [Dim Location].[All Locations].&[123]&[1])"; 

现在,我可以使用一个参数启动并运行:

 AdomdCommand cmdPDC = conPDC.CreateCommand();
        cmdPDC.CommandText = "SELECT [Dim Unit].[All Units].[Category Group Name].Members ON 0 FROM [Info] WHERE (StrToMember(@P1)";

        string companyid = "123";

        string sP1 = "[Dim Company].&" + company;

    cmdPDC.Parameters.Add(new AdomdParameter("P1", sP1));

但是,如何实现第二个参数,例如,如果我想在参与位置中添加参数?我正沿着下面的思路思考,但我无法让小小的草皮工作:

AdomdCommand cmdPDC = conPDC.CreateCommand();
        cmdPDC.CommandText = "SELECT [Dim Unit].[All Units].[Category Group Name].Members ON 0 FROM [Info] WHERE (StrToMember(@P1)," + "(StrToMember(@P2))";

        string companyid = "123";
        string locationid = "1";

        string sP1 = "[Dim Company].&" + company;
        string sP2 = "[Dim Location].&" + company + "&" + location;

        cmdPDC.Parameters.Add(new AdomdParameter("P1", sP1));
        cmdPDC.Parameters.Add(new AdomdParameter("P2", sP2));

感激不尽的任何帮助或建议。

解决方案!

AdomdCommand cmdPDC = conPDC.CreateCommand();
cmdPDC.CommandText = "SELECT NON EMPTY [Dim Unit].[All Units].[Category Name].Members ON 0 FROM [MY CUBE] WHERE (StrToMember(@CompanyId),StrToMember(@LocationId))";

string companyid = "[123]";
string locationid = "[1]";

string sCompanyId = "[Dim Company].&" + companyid;
string sLocationId = "[Dim Location].&" + companyid + "&" + locationid;

cmdPDC.Parameters.Add(new AdomdParameter("CompanyId", sCompanyId));
cmdPDC.Parameters.Add(new AdomdParameter("LocationId", sLocationId));

还有一些小指示。

您可能会收到此错误:

“无法解析X参数,因为它在内部子表达式中被引用”

解决方案:在引用的字符串中插入@CompanyId时,请确保参数未包含在撇号(')中 - c#很聪明并将转换数据类型并为您添加这些撇号。但是,您将无法在观察窗口中看到它,一切看起来都没问题。

返回所有项目,看起来您的参数被忽略。

解决方案:检查第一个SELECT并确保它是SELECT NON EMPTY

SELECT NON EMPTY { 
[Measures].[Phone Count], 
[Measures].[Mail Count], 
[Measures].[Individual Count] 
} ON COLUMNS 
FROM [PyramidReports-US] 
WHERE ( 
 (STRTOSET(@PoliticalGeographyByCD), 
 [Political Geography].[By CD].[State].currentmember ), 
 (STRTOSET(@GenderGender), 
 [Gender].[Gender].currentmember ), 
 (STRTOSET(@ModelAffinityAffinityQuartile), 
 [Model Affinity].[Affinity Quartile].currentmember 
  ) 

使用currentmember填充参数这样的查询怎么样?
