Example 1:

create.selectFrom(BOOK)
      .where(BOOK.PUBLISHED_IN.eq(2011))
      .orderBy(BOOK.TITLE)

Example 2:

create.select(AUTHOR.FIRST_NAME, AUTHOR.LAST_NAME, count())
      .from(AUTHOR)
      .join(BOOK).on(AUTHOR.ID.equal(BOOK.AUTHOR_ID))
      .where(BOOK.LANGUAGE.eq("DE"))
      .and(BOOK.PUBLISHED.gt(date("2008-01-01")))
      .groupBy(AUTHOR.FIRST_NAME, AUTHOR.LAST_NAME)
      .having(count().gt(5))
      .orderBy(AUTHOR.LAST_NAME.asc().nullsFirst())
      .limit(2)
      .offset(1)

Type-safety example:

select().from(t).where(t.a.eq(select(t2.x).from(t2));
// Type-check here: ---------------> ^^^^
select().from(t).where(t.a.eq(any(select(t2.x).from(t2)));
// Type-check here: -------------------> ^^^^
select().from(t).where(t.a.in(select(t2.x).from(t2));
// Type-check here: ---------------> ^^^^
