如何计算 android 上 SQLite DB 中每条记录的值并更新该值？

Question

My database has several records and each record has object's location (2 fields: latitude and longitude). I need to calculate the distance from the current user's location to each object (with distanceBetween method). Then this value should be written into another database field (distance).

How should I do that?

Answer 1

You shouldn't... calculated fields should not be stored. You should calculate things as you need them.
