    This type is used for the 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

   SELECT T_AUTHOR.FIRST_NAME, T_AUTHOR.LAST_NAME, COUNT(*)
     FROM T_AUTHOR
     JOIN T_BOOK ON T_AUTHOR.ID = T_BOOK.AUTHOR_ID
    WHERE T_BOOK.LANGUAGE = 'DE'
      AND T_BOOK.PUBLISHED > '2008-01-01'
 GROUP BY T_AUTHOR.FIRST_NAME, T_AUTHOR.LAST_NAME
   HAVING COUNT(*) > 5
 ORDER BY T_AUTHOR.LAST_NAME ASC NULLS FIRST
    LIMIT 2
   OFFSET 1
      FOR UPDATE
       OF FIRST_NAME, LAST_NAME
       NO WAIT
    Its equivalent in jOOQ 
     create.select(TAuthor.FIRST_NAME, TAuthor.LAST_NAME, create.count())
       .from(T_AUTHOR)

        Add a synthetic SEEK AFTER clause to the query.

        The synthetic SEEK AFTER clause is an alternative way to specify an OFFSET, and thus to perform paging in a SQL query. This can be advantageous for two reasons:

        1. The SQL generated from the SEEK AFTER clause is a regular predicate, which can be used by query plan optimisers to choose an appropriate index. The SQL standard OFFSET clause will need to skip N rows in memory.
        2. The SEEK AFTER clause is stable with respect to new data being inserted or data being deleted while paging through pages.

        Example: 

         DSL.using(configuration)
    .selectFrom(TABLE)
    .orderBy(ID, CODE)
    .seekAfter(3, "abc")
    .fetch();

        The above query will render the following SQL statement: 

         SELECT table.col1, table.col2, ... FROM table
 WHERE (id, code) > (3, 'abc')
 ORDER BY id ASC, code ASC

        The actual row value expression predicate may be expanded into this equivalent predicate: 

         WHERE (id > 3) OR (id = 3 AND code > 'abc')

        The SEEK AFTER method currently does not support seeking NULL values, or operating with NULLS FIRST, NULLS LAST clauses in the ORDER BY clause.
