节点js sql查询内连接

Question

你能帮我解决一下这个关于INNER JOIN的SQL查询吗？ 结果返回错误

connection.query("SELECT caracavis.caracname FROM caracavis WHERE firstcaturl ='" + req.body[0].firstcatname + "' AND secondcaturl = '" + req.body[0].secondcatname + "' AND thirdcaturl = '" + req.body[0].thirdcatname + "' AND fourthcaturl = '" + req.body[0].fourthcatname + "' AND fifthcaturl = '" + req.body[0].fifthcatname + "' INNER JOIN critereproducts ON caracavis.caracname = critereproducts.nameurl", function (error, results, fields) {
				if (!!error) {
					console.log('erreur');
				} else {
					console.log(results);
					// res.json(results);
				};
			});
