Public Property Source As String

public string Source { get; set; }

public:
property String^ Source {
    String^ get ();
    void set (String^ value);
}

/** @property */

/** @property */
public void set_Source (String value)

public function get Source () : String

public function set Source (value : String)

属性值

The text of the DDL statement to be sent to the Analysis Services server.

备注

This property works with the SourceType property. If the source type is a variable, and the variable is null, the String returned is empty. If the source type is a connection and there is an error retrieving the connection, the String returned is empty.

The DDL statement consists of an XML for Analysis (XMLA) statement that contains the XMLA Create, Alter, or Delete commands, in a format like the example that follows:

<Create xmlns="https://schemas.microsoft.com/analysisservices/2003/engine">

<ParentObject>

<DatabaseID>Adventure Works DW</DatabaseID>

</ParentObject>

<ObjectDefinition>

<Dimension xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

<ID>Dim Customer</ID>

<Name>Customer</Name>

示例

The following code sample creates, configures, and executes a new ASExecuteDDLTask that loads the DDL statement to execute from a file connection. The sample uses the Source property.

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("MSOLAP90");
    asCM.Name = "Analysis Services Connection Manager";
    asCM.ConnectionString = "Data Source=<servername>;" +
      "Initial Catalog=Adventure Works DW;Provider=MSOLAP.3;" +
      "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, " +
      "Microsoft.SqlServer.ASTasks, Version=9.0.242.0, " +
      "Culture=neutral, PublicKeyToken=89845dcd8080cc91");
    TaskHost thTask = (TaskHost) exe;
    {
      thTask.Properties("ConnectionName").SetValue(thTask, "Analysis Services Connection Manager");
      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();
    }

  }

}
