Question

basket:
id: integer primary key
key: integer

product:
id: integer primary key
basket: foreign key Basket.id
price: integer

引起：android.database.sqlite.SQLiteException：误用 aggregate：MIN（）（Sqlite代码1）:,编译时：
SELECT `basket`.* FROM `basket` LEFT JOIN `product` ON `basket`.`id` =  `product`.`basket` WHERE `basket`.`key` = 11 GROUP BY `basket`.`id` ORDER BY MIN(price) DESC LIMIT 100 OFFSET 20 (OS error - 2:No such file or directory)

Android版。 7.0。它适用于Android 4/5/6。它不适用于Android 7.0。有什么问题？

Answer 1

我不是因为你可以按顺序使用聚合函数。试试：

SELECT basket.*, MIN(price) As minPrice
  FROM basket
  LEFT JOIN product
    ON basket . id = product . basket
 WHERE basket . key = 11
 GROUP BY basket . id
 ORDER BY minPrice  DESC LIMIT 100 OFFSET 20

滥用＆gt;聚合：MIN（）
