ora 00942錯誤：表或​​視圖不存在

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; 

它一直說表或視圖不存在，但當我從書籍中選擇*時;它確實讓我看到了桌子。

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已被評論。應改爲book_author。還包括select子句中的列名之前的表名
