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();

Referencing XYZ*Step types directly from client code

It is usually not recommended to reference any XYZ*Step types directly from client code, or assign them to local variables. When writing dynamic SQL, creating a statement's components dynamically, and passing them to the DSL API statically is usually a better choice. See the manual's section about dynamic SQL for details: https://www.jooq.org/doc/latest/manual/sql-building/dynamic-sql.

Drawbacks of referencing the XYZ*Step types directly:

  • They're operating on mutable implementations (as of jOOQ 3.x)
  • They're less composable and not easy to get right when dynamic SQL gets complex
  • They're less readable
  • They might have binary incompatible changes between minor releases
