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.
