Do i have to use _ID as a SQlite primary key? and does it have to be an INT? (Android Dev)

Question

This is probably a silly question but i haven\'t been able to find the answer yet.

I want to use a TEXT column with my own unique names as the primary key in a table

Answer 1

_id must be of type int in sqlite create (long in Java). Various classes assume that. As a result, you cannot use UUID for primary key.
