sequelize.sync()：NUMBER 附近的 SQL 语法错误

Question

我使用 制作了 4 个 Sequelize 模型sequelize.define();。模型几乎是相同的东西，但表名不同。因为我不想在 MySQL cli 上手动创建它们，所以我决定在我的主 index.js 文件中使用 Sequelize.sync() 来让 Sequelize 创建表，但是当我运行应用程序时，它遇到了错误Unhandled rejection SequelizeDatabaseError: You have an error in your SQL syntax;并且没有'不做桌子。

我已经尝试过这两种sequelize.sync();方法sequelize.sync({ force: true }); ，也尝试过一一同步模型，但出现了相同的错误！

我的模特之一

export const Product = sequelize.define(
  "product",
  {
    doInMyPlace: { type: Sequelize.BOOLEAN, allowNull: false },
    address: { type: Sequelize.STRING, allowNull: false },
    mapAddress: { type: Sequelize.STRING, allowNull: false },
    date: { type: Sequelize.STRING, allowNull: false },
    time: { type: Sequelize.STRING, allowNull: false },
    voucher: { type: Sequelize.STRING, allowNull: true },
    companyName: { type: Sequelize.STRING, allowNull: false },
    phoneNumber: { type: Sequelize.STRING, allowNull: false },
    itemCount: { type: Sequelize.NUMBER, allowNull: false }
  },
  {
    freezeTableName: true
  }
);

显示错误

Unhandled rejection SequelizeDatabaseError: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'NUMBER NOT NULL, `createdAt` DATETIME NOT NULL, `updatedAt` DATETIME NOT NULL, P' at line 1

由于该错误针对 SQL 语法，我想知道它是否与我的代码有关，或者只是sequelize 本身的问题。

Answer 1

您应该使用INTEGER而不是NUMBER. 就像这样：

itemCount: { type: Sequelize.INTEGER, allowNull: false }

查看文档，没有提及数据类型NUMBER。虽然我确实找到了这个，但它只是用作其他数据类型的基类。

至于INTEGER，您有以下内容：

Sequelize.INTEGER.UNSIGNED              // INTEGER UNSIGNED
Sequelize.INTEGER(11).UNSIGNED          // INTEGER(11) UNSIGNED
Sequelize.INTEGER(11).ZEROFILL          // INTEGER(11) ZEROFILL
Sequelize.INTEGER(11).ZEROFILL.UNSIGNED // INTEGER(11) UNSIGNED ZEROFILL
Sequelize.INTEGER(11).UNSIGNED.ZEROFILL // INTEGER(11) UNSIGNED ZEROFILL

顺便说一句，你的错误是因为这一行而发生的， MYSQL 中'itemCount' NUMBER NOT NULL没有数据类型。NUMBER
