Javascript 获取SyntaxError:缺少）后参数列表 var记录=”； 对于（变量i=0；i

错误出现在带有wierd引号的select语句中

var records = "";
for(var i = 0; i < activity.length; i++) {
sequelize.query("SELECT * from users WHERE city = '"+city+"'" AND categories LIKE CONCAT('%', activity[i], '%')"", { type: sequelize.QueryTypes.SELECT})
    .then(function(logs){ 
        records += logs;
        matchCount += logs.length;

    }); 
}

console.log("--------------------------Priniting matched users-----------------------");
console.log(records);

//INSERT DATA TO SQL

sequelize.query("INSERT INTO users(name, lastname, email, phone, city, categories, createdAt, updatedAt) VALUES ('"+req.body.first_name+"', '"+req.body.last_name+"', '"+req.body.email+"',  '"+req.body.tel+"', '"+req.body.city+"', , '"+JSON.stringify(activity)+"', 'test', 'test')");

var记录=”；
对于（变量i=0；i

你必须更加注意字符串引号，你把

city

的结束简单引号和

和categories

部分搞砸了

应该是这样的：

var records = "";
for (var i = 0; i < activity.length; i++) {
    sequelize.query("SELECT * from users WHERE city = '" + city + "'AND categories LIKE CONCAT('%', activity[i], '%')", {
            type: sequelize.QueryTypes.SELECT
        }).then(
        function(logs) {
            records += logs;
            matchCount += logs.length;
        });
}

console.log("--------------------------Priniting matched users-----------------------");
console.log(records);

//INSERT DATA TO SQL

sequelize.query("INSERT INTO users(name, lastname, email, phone, city, categories, createdAt, updatedAt) VALUES ('" + req.body.first_name + "', '" + req.body.last_name + "', '" + req.body.email + "', '" + req.body.tel + "', '" + req.body.city + "', , '" + JSON.stringify(activity) + "', 'test', 'test')");

另外，在将变量连接到SQL字符串查询中时要小心，如果不清理它们，可能会成为循环中的

sequelize.query

调用的受害者。语法突出显示对您来说合适吗？一个好的语法突出显示编辑器会对您有所帮助。特别是如果编辑器本身也有任何类型的错误检查。打字：

“+city+”“

我打赌它会给出一个行号，champ

sequelize.query("SELECT * from users WHERE city = '"+city+"' AND categories LIKE CONCAT('%', activity[i], '%')", { type: sequelize.QueryTypes.SELECT})
