获取具有id的行列表，按其他ID分组

Question

我在Android中使用SQLite（minSdkVersion：15）。我有这样的表：

我试图以trainingId作为参数获取最后插入行的列表。例如，我想获取带有trainingId = 1的最后插入行的列表，结果应为：

13---5---1 14---5---1 15---5---1

或trainingId = 2，然后：

10---4---2 11---4---2 12---4---2

我试过这样的事情：

SELECT * FROM table_name JOIN (SELECT MAX(trainingDoneId) AS trainingDoneId FROM table_name GROUP BY treningId) USING (trainingDoneId)

和

SELECT * FROM table_name WHERE trainingDoneId IN (SELECT MAX(trainingDoneId) FROM table_name GROUP BY 1)

但在这两种情况下我都会收到此错误：

android.database.sqlite.SQLiteException: aggregate functions are not allowed in the GROUP BY clause (code 1)

有什么建议吗？

Answer 1

请点击以下查询它会帮助你，

  SELECT * FROM table_name where trainingId = 1 AND trainingDoneId in (select max(trainingDoneId) from table_name where trainingId = 1)

Answer 2

SELECT id, MAX(trainingDoneId), trainingId FROM table_name WHERE trainingId = 1 ORDERBY id
