* 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:
*
*
* - 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.
* - 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)
* .seek(3, "abc")
* .fetch();
*
* The above query will render the following SQL statement:
*
*
* SELECT * 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.
