Android Sqlite查询在4.0中运行，但在2.3中不运行

Question

我在Android中的数据库上运行以下查询

SQLiteDatabase db = this.getWritableDatabase();
Cursor c;

String Query = "Select * from SubCategory_List where CatId = (Select _id from Category_List where Name = ?) order by Name ASC";

c = db.rawQuery(Query, new String[] { CatName });

我使用此光标填充listview。在android 4.0中我获得了所需的输出，但是在2.3中没有显示vales。

Answer 1

改变这个：

String Query = "Select * from SubCategory_List where CatId = (Select _id from Category_List where Name = ?) order by Name ASC";

由此：

String Query = "Select * from SubCategory_List where CatId IN (Select _id from Category_List where Name = ?) order by Name ASC";

（更改=进入IN）
