ora 00942错误：表或​​视图不存在

Question

Select lname, fname, title as "Book Title" 
from books join line
on books.bookid = book_author.bookid
join author
on author.authorid = book_author.authorid;

它一直说表或视图不存在，但是当我从书中选择*时;它确实向我展示了这张桌子。

Answer 1

Select author.lname, author.fname, books.title as "Book Title" 
from books join book_author --line
on books.bookid = book_author.bookid
join author
on author.authorid = book_author.authorid;

line已被评论过。它应该是book_author。还包括select子句

中列名称之前的表名
