sequelize.sync(): error in SQL syntax near NUMBER

Question

I made 4 Sequelize Models with use of sequelize.define();. Models are pretty much the same thing but with different table names. since I don't wanted to make them manually on MySQL cli, I decided to use sequelize.sync() in my main index.js file to let Sequelize to create the table but when I ran the application It faced an Unhandled rejection SequelizeDatabaseError: You have an error in your SQL syntax; error and didn't make the tables.

I have tried both sequelize.sync(); and sequelize.sync({ force: true }); and also tried syncing Models one by one but same error apeared!

one of My Models

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
  }
);

Shown Error

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

Since the error aims at SQL syntax I was wondering if it has something to do with my code or is just an issue with sequelize itself.

Answer 1

You should use INTEGER instead of NUMBER. Like so:

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

Looking at the docs, there is no reference to a datatype NUMBER. Although I did find this but its just used as a base class for other datatypes.

As for INTEGER, you have the following:

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

By the way, your error happens because of this line 'itemCount' NUMBER NOT NULL, there is no NUMBER datatype in MYSQL.

Answer 2

Datatypes supported in sequelize:

https://sequelize.readthedocs.io/en/1.7.0/docs/models/

So use INTEGER instead of NUMBER.
