Esempio
L'esempio di codice seguente crea, configura ed esegue una nuova ASExecuteDDLTask istruzione che carica l'istruzione DDL da eseguire da una connessione file. L'esempio usa l'enumerazione DDLSourceType .
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();
}
}
}
