C#-Codelisting für BatchQueryFindAllEmps

Diese Funktion wird in zukünftigen Versionen von Microsoft SQL Server nicht mehr bereitgestellt. Verwenden Sie diese Funktion beim Entwickeln neuer Anwendungen nicht, und planen Sie das Ändern von Anwendungen, in denen es zurzeit verwendet wird.

Das folgende Beispiel erstellt BatchQueryFindAllEmps.

private void BatchQueryFindAllEmps_Click(System.Object sender, System.EventArgs e)
{
   server.sql_endpoint proxy = new server.sql_endpoint ();

   proxy.Credentials = System.Net.CredentialCache.DefaultCredentials;
   listBox1.Items.Add ("1) Executing batch.  ");
   listBox1.Items.Add ("");

   NativeSOAPApp1.server.SqlParameter[] p = null;
   string s = "SELECT FirstName, LastName " + "FROM  Employee " + "FOR XML AUTO;";
   object[] results = proxy.sqlbatch (s, ref p);

   for (int j = 0; j < results.Length; j++)
   {
object e1;
server.SqlMessage errorMessage;
System.Xml.XmlElement xmlResult;
e1 = results[j];

//return value from SP is an int
if (e1.GetType ().IsPrimitive)
{
   listBox1.Items.Add ("Return code = ");
   listBox1.Items.Add (e1);
}

switch (e1.ToString ())
{
   case "NativeSOAPApp1.server.SqlRowCount":
listBox1.Items.Add ("Printing Sql Row count returned");
listBox1.Items.Add ("The type of the row count element in obj array is: ");
listBox1.Items.Add (e1.ToString ());
listBox1.Items.Add ("Row count =");
listBox1.Items.Add (((NativeSOAPApp1.server.SqlRowCount)results[j]).Count);
break;

   case "System.Xml.XmlElement":
listBox1.Items.Add ("Printing result of SELECT ...FOR XML");
listBox1.Items.Add ("The type of the result in obj array is: ");
listBox1.Items.Add (e1.ToString ());
listBox1.Items.Add ("This is the result :");
xmlResult = (System.Xml.XmlElement)results[j];
listBox1.Items.Add (xmlResult.OuterXml);
break;

   case "NativeSOAPApp1.server.SqlMessage":
listBox1.Items.Add ("Printing error msg, warning or other informational msg:");
listBox1.Items.Add ("The type of the corresponding  obj array element is: ");
listBox1.Items.Add (e1.ToString ());
listBox1.Items.Add ("This is the msg :");
errorMessage = (server.SqlMessage)results[j];
listBox1.Items.Add (errorMessage.Message);
listBox1.Items.Add (errorMessage.Source);
break;
}
   }
