Thank you for contacting us.
Based on the provided information it looks like your model was initially created to work with a Microsoft SQL Server database. Since the model contains mapping that is specific for the database engine it targets, it cannot be used with another database engine. This could be the cause of the errors you are experiencing.
With this in mind we would recommend re-creating your model based on your MySQL database using the Database First approach
Alternatively if you need your model to work with the same database schema on different backends you can try using a Fluent Model
with Backend Independent Mapping
I hope this helps. Should you have further questions, feel free to post at our forums.
