Hi,

when a database query retrieves a Cursor, what does it have in fact? I mean,
does it have the whole result set in memory or keep a kind of "pointer" to
each result row, and when I do cursor.moveToNext() it points to the next
row? Or anything else?

I need to deal with a long list of data, and I really wanna know how
efficient is a Cursor retrieved from a database query.

Thanks,
Taísa
