We have a requirement to have an Appian document (file) inserted into a database

Could you please elaborate a bit on your use case for having the document stored in the database? Typically, you should have the document stored on the server and use the Document ID to reference the document when necessary.

The application group that is requesting this does not have a server to store documents. They currently store the workflow data into a database and they want to also store the document into a varbinary(max) field and the document name into a nvarchar(256) field. According to the application group, this file can be recreated with a program that runs outside of Appian with these two fields at a later time.

This is approach is not recommended, for performance reasons. I'll follow up with you separately and we can discuss this in more detail.
