Android SQLite范围查询

Question

我正在使用它：

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

我想使用范围而不是像10到20那样修复。

Answer 1

您的操作方式与SQL相同;

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

SQL WHERE Clause

Answer 2

要检查某些值是否介于某些其他值之间，请使用BETWEEN operator：

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