How to pass a DateTime from NodeJS Sequelize to MSSQL

Question

I have a NodeJS project, and I am trying to pass an \'UpdateDate\' field using Sequelize. I am receiving the error \'Conversion failed when converting date and/or time from char

Answer 1

This is caused by a known issue in Sequelize. The solution is to patch Sequelize's date to string format implementation, like explained here, so that all dates are handled properly. Below is the code that fixes the error.

const Sequelize = require('sequelize');

// Override timezone formatting for MSSQL
Sequelize.DATE.prototype._stringify = function _stringify(date, options) {
  return this._applyTimezone(date, options).format('YYYY-MM-DD HH:mm:ss.SSS');
};
