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

I figured this out, without changing the data type in the SQL database.

In my Model, I had my column defined as DataTypes.DATE, which, according to the Sequelize documentation, is the equivalent of a DateTime in SQL. However, this was throwing the error. When I changed the definition to DataTypes.STRING, and then added this:

var normalizedDate = new Date(Date.now()).toISOString();

normalizedDate now passes through to the DateTime column in SQL without a problem. The issue that I can tell, is Sequelize was adding a time zone to the Date before passing it. Such as, a date like:

'2017-11-01 16:00:49.349'

was being passed through as:

'2017-11-01 16:00:49.349 +00:00'

and it looks like SQL server does not like the '+00:00'.

I hope this helps others.
