Properties

  Name Description
Public property ConnectionName Infrastructure. (Inherited from ASTaskBase.)
Public property ExecutionValue Returns the result of the task execution. (Overrides Task.ExecutionValue.)
Protected property ProgressEventName Infrastructure. (Inherited from ASTaskBase.)
Public property Source Gets or sets the text of the DDL statement to be sent to the Analysis Services server.
Public property SourceType Gets or sets a value from the DDLSourceType enumeration indicating the source type that contains the DDL statements.
Protected property StatusEventName Infrastructure. (Overrides ASTaskBase.StatusEventName.)
Protected property SubComponentName Infrastructure. (Overrides ASTaskBase.SubComponentName.)
Public propertyStatic member TaskDescription Returns a description of the Analysis Services Execute DDL task.
Public propertyStatic member TaskDisplayName Returns the name of the Execute DDL task.
Public property Version *** Member deprecated; see Remarks. ***    Returns the version of the task. This property is read-only. (Inherited from Task.)

Methods

  Name Description
Public method CanUpdate *** Member deprecated; see Remarks. ***    A Boolean that indicates whether the new package XML can update the old package XML. (Inherited from Task.)
Public method Equals Determines whether two object instances are equal. (Inherited from DtsObject.)
Public method Execute Infrastructure. (Inherited from ASTaskBase.)
Protected method Finalize (Inherited from Object.)
Protected method FireError(String, String) Infrastructure. (Inherited from ASTaskBase.)
Protected method FireError(Int32, String, String, String) Infrastructure. (Inherited from ASTaskBase.)
Public method GetConnectionID Gets a String containing the ID of the connection. (Inherited from Task.)

Public method GetHashCode Returns the hash code for this instance. (Inherited from DtsObject.)
Public method GetType (Inherited from Object.)
Public method InitializeTask Initializes the properties associated with the task. This method is called by the runtime and is not used in code. (Inherited from Task.)
Protected method InternalExecute Infrastructure. (Overrides ASTaskBase.InternalExecute(Connections, VariableDispenser, IDTSComponentEvents, IDTSLogging, Object).)
Protected method InternalValidate Infrastructure. (Overrides ASTaskBase.InternalValidate(Connections, VariableDispenser, IDTSComponentEvents, IDTSLogging).)
Public method LoadFromXML This method is not callable by your application code. To load a package saved as .xml, use the Application.LoadPackage method.
Protected method MemberwiseClone (Inherited from Object.)

Examples

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

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, " +
      "Microsoft.SqlServer.ASTasks, Version=10.0.0.0, " +
      "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();
    }
