sequelize js插入错误

我创建了一个sequelize raw query helper函数,它将插入mysql数据库中的数据。

const addBudget = function(name, amount) {
  sequelize.query(
    'INSERT INTO budget (name, amount) VALUES(' + name + ',' + amount + ')', {
      type: Sequelize.QueryTypes.INSERT
    }
  ).then(function (data) {
    console.log('inserted STEAMER data---> ', data);     });
};

然后,当我调用函数尝试在mysql数据库中插入一些数据以查看它是否将my数据插入到记录中时:

addBudget('Book', 100);

我有个错误:

Executing (default): SELECT 1+1 AS result
Executing (default): INSERT INTO budget (name, amount) VALUES(Book,100)

你知道当我把数据插入数据库的时候我做错了什么吗?

你试过这个吗:

var sql = "insert into budget (name) values ()";
sequelize.execute(sql, function(error, result){
  console.log(result);
});

执行insert和updatesql并获取更多信息

sql只允许对值使用单引号字符串。所以,这是行不通的:

'INSERT INTO budget (name, amount) VALUES("Book", 100)'

这也不会:

'INSERT INTO budget (name, amount) VALUES(Book, 100)'

假设您指示sql将金额读取为整数,这是插入值的正确方法:

'INSERT INTO budget (name, amount) VALUES('Book', 100)'

如果book只是一个已经是字符串的变量,也可以这样做以确保保留单引号规则:

`INSERT INTO budget (name, amount) VALUES('${Book}', 100)`

这里的问题是,您的值应该包括b/w单引号或双引号,但与您的代码生成 VALUES(Book,100); ,应该是 VALUES('Book','100'); ,为此
只需更改以下行:

'INSERT INTO budget (name, amount) VALUES(' + name + ',' + amount + ')'

有了这个:

`INSERT INTO budget (name, amount) VALUES('${name}','${amount}')`
