Question

我正在尝试从SQLite数据库中获取所有来自以下模式的行，该模式以组开头，以（常规）结束。：

Group n (General)
Group n+1 (General)
Group n+1+... (General)

因为，我第一次使用SQL，目前我尝试使用原始查询，如下所示。这是抛出一个SQLException，因为我的查询不正确。

        Cursor cursor = mDatabase.rawQuery("SELECT DISTINCT " + KEY_LOCATION
            + " FROM " + FTS_VIRTUAL_TABLE + " ORDER BY " + KEY_LOCATION
            + " ASC" + " WHERE " + KEY_LOCATION + " LIKE '"
            + "%Group%%%%General%" + "'", null);

以下是执行上面的堆栈跟踪：

任何人都可以指导我如何实现它，或者可能暗示我该如何进行？

Answer 1

在ORDER BY之后设置WHERE子句。

那应该成功

Android sqlite在哪里，喜欢和orderby在一起
