的Android SQLite的範圍查詢

Question

我使用這個：

String selectQuery = "SELECT * FROM " + TABLE_QUEST+" WHERE "+KEY_ID+"=40"; 

我想使用範圍，而不是固定的像10到20

Answer 1

你的方式作爲SQL相同;

" WHERE " + KEY_ID + " >= 10 AND " + KEY_ID + " <= 20" 

SQL WHERE Clause

Answer 2

爲了檢查某個值是否是一些其他的值之間，使用BETWEEN operator：

String selectQuery = "SELECT * FROM "+TABLE_QUEST+" WHERE "+KEY_ID+" BETWEEN 10 AND 20";
