    Sql sql = new Sql("SHOW TABLES IN dreamweb_gjfgw WHERE Tables_in_dreamweb_gjfgw ='g_app_data_service_log';");
    DataTable dataTable = DBManager.getDataTable(sql);
    DataRowCollections rows = dataTable.getRows();
    for (DataRow row : rows) {
        String data = row.getString("value");
        System.out.println("存在这个值:" + data);
    }
