javascript - 我如何获取类似于数据库中字段的值？

Question

我尝试获取包含 SQL 数据库中单词的值。我尝试使用“包含”，但出现错误。我使用 SQL

这是我的代码:

router.post('/busca',isLoggedIn, async (req,res) => {
            const {busca} = req.body;
            const buscar = Object.values({busca});
            const bus = await pool.query('SELECT * FROM links WHERE title CONTAINS ?',[buscar]);
            res.render('links/busca',{buscar, bus});

        });

我有这个错误:

UnhandledPromiseRejectionWarning: Error: ER_PARSE_ERROR: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '(title, 'a')' at line 1

您可以使用 LIKE 运算符:

SELECT * FROM links WHERE title LIKE '%word%';

如果有多个单词，请使用and或or运算符

SELECT * FROM links WHERE title LIKE '%word%' AND title LIKE '%secondword%';
