Interface SelectJoinPartitionByStep

All Superinterfaces:

SelectOnStep

All Known Subinterfaces:

SelectOptionalOnStep

public interface SelectJoinPartitionByStep
extends SelectOnStep

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)
       .join(T_BOOK).on(TBook.AUTHOR_ID.equal(TAuthor.ID))
       .where(TBook.LANGUAGE.equal("DE"))
       .and(TBook.PUBLISHED.greaterThan(parseDate('2008-01-01')))
       .groupBy(TAuthor.FIRST_NAME, TAuthor.LAST_NAME)
       .having(create.count().greaterThan(5))
       .orderBy(TAuthor.LAST_NAME.asc().nullsFirst())
       .limit(2)
       .offset(1)
       .forUpdate()
       .of(TAuthor.FIRST_NAME, TAuthor.LAST_NAME)
       .noWait();
