You can think of step() as executing the select and returning one row. The "core" Sqlite3 API for selecting data is designed to be used roughly this way:

stmt = db:prepare('SELECT ...')

-- optionally stmt:bind* to set '?' values
while stmt:step() == sqlite3.ROW do
  -- A single row of resulting data has been processed.
  -- Access column data using stmt:get_*

stmt:finalize() -- if you won't use stmt again
-- or
stmt:reset() -- if you want to re-run stmt again

There are several Lua-style iterators in the API that simplify this for you, some without you needing to 'prepare' a statement beforehand, such as db:rows().
