csharp

[STAThread]
static void Main(string[] args)
{
string script =

  "INSERT INTO DEPT VALUES (10,'ACCOUNTING','NEW YORK');"+
  "INSERT INTO DEPT VALUES (20,'RESEARCH','DALLAS');"+
  "INSERT INTO DEPT VALUES (30,'SALES','CHICAGO');"+
  "INSERT INTO DEPT VALUES (40,'OPERATIONS','BOSTON');"+
  "SELECT * FROM DEPT";
      DB2Connection db2Conn = new DB2Connection(
          "user id=db2admin;server=db2;database=SAMPLE;");
      DB2Script db2Script = new DB2Script(script,db2Conn);
      db2Script.Progress += new Devart.Common.ScriptProgressEventHandler(OnProgress);
      db2Script.Error += new Devart.Common.ScriptErrorEventHandler(OnError);
      db2Conn.Open();
      db2Script.Execute();
      db2Conn.Close();
    }

static void OnProgress(object sender, Devart.Common.ScriptProgressEventArgs e)
{
  Console.WriteLine(e.Text);
  Console.WriteLine("  Successfully executed.");
}

static void OnError(object sender, Devart.Common.ScriptErrorEventArgs e)
{
  e.Ignore = true;
  Console.WriteLine(e.Text);
  Console.WriteLine("  Failed.");
