This is what I have done

C#

String scriptAndStub;

scriptAndStub =
	"DECLARE @SA_CONSOLE_HOSTNAME VARCHAR(256)\n" +
	"SET @SA_CONSOLE_HOSTNAME = @HOSTNAME@\n";
scriptAndStub += script;

executeScript.CommandText = scriptAndStub;
executeScript.Parameters.AddWithValue("@HOSTNAME@", Environment.MachineName);

I tried having breakpoints and check where the error was caught

C#

private void btnSyntaxCheck_Click(object sender, EventArgs e)
        {
            try
            {
                tsStatus.Text = "Checking Syntax...";
                LogMessage(DA_Base.Constants.ERROR_LEVEL_DEBUG, "SQLScripting::SyntaxCheck", "Query: " + rtbScript.Text);
                using (SqlCommand myCommand = new SqlCommand(string.Empty, Connection))
                {
                   foreach (string script in Regex.Split(rtbScript.Text, "^GO\r?$", RegexOptions.Multiline | RegexOptions.IgnoreCase))
                      {
                           if (!String.IsNullOrEmpty(script))
                           {
                             myCommand.CommandText = "SET PARSEONLY ON\n" + script;
                             myCommand.ExecuteNonQuery();
                            }
                       }
                 }
                 tsStatus.Text = "Checking Syntax Complete. No errors reported.";
             }
             catch (Exception exc)\\error has been caught here....
             {
                tsStatus.Text = exc.Message;
                MessageBox.Show(exc.Message, "SQL Syntax Check");
             }
         }
   }
}

Have you put a 'GO' in there? E.g.

DECLARE @SA_CONSOLE_HOSTNAME VARCHAR(256)
GO
SET @SA_CONSOLE_HOSTNAME = 'whatever'

visual studio is not letting me add "GO", am new to this if you can give a detail explanation it would be great..

MADE THESE CHANGES WORKING FINE

String scriptAndStub;

scriptAndStub =

"DECLARE @SA_CONSOLE_HOSTNAME VARCHAR(256)\n"; +

"SET @SA_CONSOLE_HOSTNAME = @HOSTNAME@\n";
executeScript.Parameters.Clear();
scriptAndStub += script;

executeScript.CommandText = scriptAndStub;
executeScript.Parameters.AddWithValue("@HOSTNAME@", Environment.MachineName);
