/**
* This type is used for the {@link Select}'s DSL API when selecting generic
* {@link 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
