摘　　要：DataWindow的数据查询,是将需查询的数据表的字段信息以DataWindow的形式传入通用数据查询窗口,在通用数据查询窗口中利用DataWindow接收用户输入的查询条件,检查条件项是否齐全,把用户输入的条件通过程序处理转换成DataWindow能够识别的合法的条件筛选语句,从而实现数据查询。Data query in DataWindow is that field information of data table needed search is inputted into general data query window in shape of DataWindow. In general data query window, DataWindow receives query condition inputted by users, and checks if query condition is integrity. Conditions inputted by users were transformed into legal condition filter sentences that can be identified by DataWindow through program processing. Thereby, general data query in DataWindow was realized.
