Android SQLite范围查询

Question

我正在使用这个：

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

我想使用范围而不是像10到20这样的固定范围。

Answer 1

您的操作方式与在SQL上相同；

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

SQL WHERE子句

Answer 2

要检查某个值是否介于其他值之间，请使用BETWEEN运算符 ：

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