android - 使用公共(public)列比较 Sqlite 中的两个表

Question

我正在创建一个应用程序，它会按时间顺序自动列出一天中的电话和短信。我完成了使用服务存储短信和调用数据库的代码。我有 2 个表:

Table Call(number, name, call_type, call_duration, date, time, time_in_milliseconds (long)) 
Table Sms(number, name, message, date, time, time_in_milliseconds (long)) 

我需要根据 time_in_milliseconds 比较两个表，并检索整行并按照 time_in_milliseconds 增加的顺序设置为 TextView 。

Answer 1

如果我理解正确，你可以使用这段代码:

        ourDatabase.rawQuery("SELECT number, name, call_type, call_duration, date, time, time_in_milliseconds " +
            " FROM Call " +
            " UNION " +
            " SELECT number, name, message, date, time, time_in_milliseconds " +
            " FROM Sms " +
            " ORDER BY time_in_milliseconds", null);
