Question

I tried following code but I couldn’t find success messages from it.Here commandText can be insert,update,delete or select query and I need dataset if it is a select query else success messages like in sql result output("12 row(s) inserted successfully").I can’t use ExecuteScalar or ExecuteNonQuery methods since I need dataset output when select query executed.

public static  DataSet ExecuteDataset(string connectionString, CommandType commandType, string commandText, params SqlParameter[] commandParameters)
    {
        using (SqlConnection cn = new SqlConnection(connectionString))
        {
            cn.InfoMessage += delegate(object sender, SqlInfoMessageEventArgs e)
            {
                MessageInfo += "\n" + e.Message;
            };
            cn.FireInfoMessageEventOnUserErrors = true;

            cn.Open();
            using (SqlCommand command = new SqlCommand(commandText, cn))
            {

                using (SqlDataAdapter adapter = new SqlDataAdapter(command))
                {
                    DataSet dt = new DataSet();
                    adapter.Fill(dt); // Do something with DataTable
                    return dt;
                }
            }
        }
    }

I managed to solve it by following way but hope there should be a better way.

 string type = Query.Trim().Split(' ')[0].ToLower();
    if ( type == "select")
    {
        DataSet result = SqlHelper.ExecuteDataset(CommandType.Text, Query);                

    }
    else
    {                
        if(type == "insert") type="inserted."; else type=type+"d.";
        int a=(int)SqlHelper.ExecuteNonQuery(CommandType.Text, Query);
        if (a > 0)
        {
            lblInfo.Text = "Query executed successfully. " + a.ToString() + " row(s) " + type;                

        }
    }

I found another one.That’s better than above one.

query = resultQuery + "  SELECT '('+CONVERT(VARCHAR(10),@@ROWCOUNT)+' row(s) affected)' AS RESULT";
DataSet result = DataSet result = SqlHelper.ExecuteDataset(CommandType.Text, query);

        if (result.DefaultViewManager.DataViewSettingCollectionString.Contains("Table") == true)
        {
            sqlGrid.Visible = true;
            sqlGrid.DataSource = result;
            sqlGrid.DataBind();
        }
        if (sqlGrid.Rows.Count==1 && sqlGrid.Rows[0].Cells.Count==1)
        {
            string text = (sqlGrid.Rows[0].Cells[0]).Text;
            if (text.Contains("row(s) affected"))
            {
                lblInfo.Text=text;
                lblInfo.Visible=true;
                sqlGrid.DataSource = null;
                sqlGrid.DataBind();
            }
        }
