添加ADOMD参数编程C＃ [英] Adding Adomd parameters programmatically C#

问题描述

下午所有。

我建立一个web应用程序，我试图通过从SSAS多维数据集的一些数据来拉。

I'm building a web app and I'm attempting to pull through some data from an SSAS cube.

我有以下MDX我想在C＃中，但与添加几个参数，即2 parameteres，一个用于公司123，另一个位置1复制：

I have the following MDX I would like to replicate in c# but with adding a few parameters i.e. two parameteres, one for company 123 and another for location 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，我能得到这个启动和一个参数运行：

Now, I can get this up and running with one parameter:

 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));

但我怎么然后实现第二个参数，例如，如果我想坚持一个参数为位置我想沿线ofbelow，但我不能让小草皮的工作：

But how do I then implement a second parameter, for example, if I wanted to stick a parameter in for location? I was thinking along the lines ofbelow but I can't get the little sod to work:

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));

任何帮助或建议感激地接受。

Any help or advice gratefully received.

推荐答案

一个解决方案

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));

和一些小球。

您可能会收到此错误：

解决方案：当带引号的字符串中插入 @CompanyId ，确保该参数不括在单引号（'） - C＃是聪明，会转换数据类型和在您添加这些撇号。但是，您将无法看到它在监视窗口和所有似乎是罚款。

Resolution: When inserting the @CompanyId in the quoted string, make sure the parameter is not enclosed in apostrophes (') - c# is clever and will convert the data type and add these apostrophes in for you. However, you won't be able to see it in a watch window and all would appear to be fine.

所有项目都回来了，这样看来，你的参数。被忽略

All items are returned and it would appear that your parameters are being ignored.

解决方法：检查的第一 SELECT ，并确保它是 SELECT NON EMPTY 。

Resolution: Check the very first SELECT and make sure it is SELECT NON EMPTY.
