public interface SelectWindowStep<R extends Record> extends SelectOrderByStep<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

GROUP BY T_AUTHOR.FIRST_NAME, T_AUTHOR.LAST_NAME

WINDOW clause to the statement.
Use the WINDOW clause to specify window definitions for
reuse among several window functions.
Only SQLDialect.POSTGRES and SQLDialect.SYBASE are known
to support the SQL standard WINDOW clause, but you can still
use this clause in all other databases supporting window functions. jOOQ
will inline window definitions where they are referenced.
