    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(*)

        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.
