The field "_id" is not technically mandatory (documentation citing), however, if you use the Cursor who inherits from CursorAdapter, it will be necessary to have a field "_id" on your table.

You can use the method ".rawQuery(sql, [selectionArgs = default null])" if you do not want to implement _id in your table that will suit you as ". query".

I used this ghastly calling to play the launch on Listview... Would you redo this method . rawQuery? I’m new to database and I started learning this week.

Taking advantage, if you can help me... I have to do some methods later to get values of each release and deal with the dates. How to work with these freaks, I get confused because mixed with DB. Is it a correct way to do like, Arraylist list = Lancamentodao.insert(this); ?? Excuse anything.
