Apps SQLite Table primary key

[Mihály Szalia]

What kind of arguments can be the primary key of sqlite database table? Does it need to be an integer argument with name "_id" with auto increment, or can I choose some other names, and types for that?

As far as I know, you can make any column name a primary key, and it does not have to be auto increment. But having it as _id with auto increment does have it's advantageous, like most of androids list adapters expect a column with that name to work properly.
