node.js - 我想通过 sequelize 更改表的列名

Question

我正在尝试使用queryInterface更改表中列的名称，但下面的代码不起作用。为什么是这样？

const sequelize = require('sequelize')
const queryInterface = sequelize.getQueryInterface();

错误：queryInterface 不是函数

标签： node.jssequelize.js

Answer 1

queryInterface在您的 Sequelize 实例上可用。见获取查询接口

const { Sequelize, DataTypes } = require('sequelize');
const sequelize = new Sequelize(/* ... */);
const queryInterface = sequelize.getQueryInterface();
