Mysql搜索查询两列

Question

我正在为我的网站建立一个搜索功能，并希望通过两列搜索：标题和作者。

查询：

SELECT title, bookID, publisher, pubDate, book_image, books.authorID, authors.author FROM books, authors WHERE books.authorID = authors.authorID 
            AND title LIKE '$queryString%' OR author LIKE '$queryString%'LIMIT 5

当我按标题搜索时，这工作正常，但是当我按作者搜索时，我会获得所有书籍的列表，其中搜索作者为作者。显然这是不正确的。

如何修复此查询以成功搜索标题或作者？

Answer 1

尝试以下：

SELECT title, bookID, publisher, pubDate, book_image, books.authorID, authors.author 
FROM books left join  authors on  books.authorID = authors.authorID 
WHERE (title LIKE '$queryString%' OR author LIKE '$queryString%') LIMIT 5

我建议你在mysql中使用fulltext搜索。这会更快更有效率

Answer 2

SELECT title, bookID, publisher, pubDate, book_image, books.authorID, authors.author 
FROM books, authors 
WHERE books.authorID = authors.authorID 
        AND (title LIKE '$queryString%' OR author LIKE '$queryString%')LIMIT 5

这应该做的工作

Answer 3

尝试一下：

SELECT bk.title, bk.bookID, bk.publisher, bk.pubDate, bk.book_image, bk.authorID, au.author
FROM books bk,  authors au
WHERE bk.authorID = au.authorID AND bk.title LIKE '$queryString%' OR au.author LIKE '$queryString%' LIMIT 5
