This type is used for the Select

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())

public interface SelectSeekStep2<R extends Record, T1, T2> extends SelectLimitStep<R> {
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 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.
