Contoh

Sampel kode berikut membuat, mengonfigurasi, dan menjalankan yang baru ASExecuteDDLTask yang memuat pernyataan DDL untuk dijalankan dari koneksi file. Sampel menggunakan Source properti .

using Microsoft.SqlServer.Dts.Runtime;  
using Microsoft.DataTransformationServices.Tasks.DTSProcessingTask;  

class Module1  
{  

  public static void Main()  
  {  

    Package pkg = new Package();  

    ConnectionManager asCM;  
    asCM = pkg.Connections.Add("MSOLAP100");  
    asCM.Name = "Analysis Services Connection Manager";  
    asCM.ConnectionString = "Data Source=<servername>;" +  
      "Initial Catalog=Adventure Works DW;Provider=MSOLAP;" +  
      "Integrated Security=SSPI;Impersonation Level=Impersonate;";  

    ConnectionManager cmdCM;  
    cmdCM = pkg.Connections.Add("FILE");  
    cmdCM.Name = "Command Source Connection Manager";  
    cmdCM.ConnectionString = "C:\\ddltest.txt";  

    Executable exe = pkg.Executables.Add("Microsoft.DataTransformationServices.Tasks.DTSProcessingTask.ASExecuteDDLTask, " +

      thTask.Properties("SourceType").SetValue(thTask, DDLSourceType.FileConnection);  
      thTask.Properties("Source").SetValue(thTask, "Command Source Connection Manager");  
    }  

    DTSExecResult valResults = pkg.Validate(pkg.Connections, pkg.Variables, null, null);  

    if (valResults==DTSExecResult.Success)  
    {  
      pkg.Execute();  
    }  

  }

Keterangan

Properti ini berfungsi dengan SourceType properti . Jika jenis sumber adalah variabel, dan variabelnya null, yang String dikembalikan kosong. Jika jenis sumber adalah koneksi dan ada kesalahan saat mengambil koneksi, koneksi yang String dikembalikan kosong.

Pernyataan DDL terdiri dari pernyataan XML untuk Analisis (XMLA) yang berisi perintah XMLA Create, , Alteratau Delete , dalam format seperti contoh berikut:
