type DDLSourceType = 

Public Enum DDLSourceType

Herança

Enum

DDLSourceType

Campos

DirectInput	0	Indica que a fonte DDL está contida na propriedade Source.
FileConnection	1	Indica que a fonte DDL está contida em uma conexão de arquivo.
Variable	2	Indica que a fonte DDL está contida em uma Variable.

Exemplos

O exemplo de código a seguir cria, configura e executa um novo ASExecuteDDLTask que carrega a instrução DDL a ser executada a partir de uma conexão de arquivo. O exemplo usa a DDLSourceType enumeração.

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, " +

      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();  
    }  

  }
