android - Is 'ORDER BY _id' enough to get rows in insertion order?

Question

I'm using SQLite DB in my Android app. Now I need to implement data extraction in the same order in which it was inserted. Is it enough to do SELECT ... ORDER BY _id ... if the _id column is INTEGER PRIMARY KEY AUTOINCREMENT? Or should I add a column to store the date and time a row has been created?

Answer 1

不用了，一个AUTOINCREMENT生成的id就够了。

Answer 2

是的，如果您只需要订单，您可以使用这样的语句或只是简单的“SELECT ... FROM sometable”。结果将是平等的。

Answer 3

您可以使用ORDER BY _id. 确保您使用的是 List 而不是 Set....
