public interface SelectOffsetStep<R extends Record> extends SelectForUpdateStep<R>
Select's DSL API when selecting generic
Record types.
Example:
-- get all authors' first and last names, and the number
-- of books they've written in German, if they have written
-- more than five books in German in the last three years
-- (from 2011), and sort those authors by last names
-- limiting results to the second and third row

your RDBMS, or if your RDBMS does not natively support offsets, this is
emulated with a ROW_NUMBER() window function and nested
SELECT statements.
