Question

我创建了一个sequelize raw query辅助函数，它将从我的mysql数据库中插入数据。

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数据库上插入一些数据时，看它是否将我的数据插入到记录中：

addBudget('Book', 100);

我收到了这个错误：

Executing (default): SELECT 1+1 AS result
Executing (default): INSERT INTO budget (name, amount) VALUES(Book,100)
Unhandled rejection SequelizeDatabaseError: Unknown column 'Book' in 'field list'

在将数据插入数据库时，不知道我在做什么？

Answer 1

这里的问题是你的价值应该用单引号或双引号括起来，但是你的代码会生成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}')`

Answer 2

SQL仅允许将单引号字符串用作您的值。因此，这将不起作用：

'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读取整数形式的金额，这是插入值的正确方法：

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

如果Book只是已经是字符串的变量，则还可以执行此操作以确保保留单引号规则：

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

Answer 3

你试过这个：

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

执行insert和update sql并获取更多信息
