JOOQ:Returning 多个用户定义的对象

Question

是否可以使用Jooq获取多个用户定义的对象。例如，我可以做这样的事情吗？

Factory create = new Factory(connection, SQLDialect.MYSQL);
     create.select(AUTHOR,BOOK).from(BOOK).
    JOIN(AUTHOR).ON(AUTHOR.AUTHOR_ID.equal(BOOK.AUTHOR_ID)).fetch();

正如我们所做的那样，

    create.select(AUTHOR.AUTHOR_ID,BOOK.BOOK_ID,BOOK.BOOK_NAME).from(BOOK).
JOIN(AUTHOR).ON(AUTHOR.AUTHOR_ID.equal(BOOK.AUTHOR_ID)).fetch();

错误信息：

Error:(52, 16) java: no suitable method found for select(...)

AUTHOR、BOOK 是数据库中的表，JOOQ 自动代码生成器已用于为它们生成类。

任何建议表示赞赏:)

Answer 1

您可以为此使用 Result.into(Table)：

Result<Record> result =
create.select()
      .from(BOOK)
      .join(AUTHOR).
      .on(AUTHOR.AUTHOR_ID.equal(BOOK.AUTHOR_ID))
      .fetch();

BookRecord book = result.into(BOOK);
AuthorRecord author = result.into(AUTHOR);
