/**
|
|
* This type is used for the {@link Select}'s DSL API when selecting generic
|
|
* {@link Record} types.
|
|
* <p>
|
|
* Example: <code><pre>
|
|
* -- 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
|
|
* </pre></code> Its equivalent in jOOQ <code><pre>
|
|
* 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();
|
|
* </pre></code> Refer to the manual for more details
