public interface SelectForUpdateWaitStep<R extends Record> extends SelectOptionStep<R>
Select's DSL API when selecting generic
Record types.
Example:

-- 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
