How to save the trained model to relational database?

I have found the @michaelgsharp 's sample
https://github.com/dotnet/machinelearning-samples/tree/main/samples/csharp/getting-started/DatabaseLoader
But how to save/load the trained(!) model to a database to fast use it?
For example, for prediction or as for me: I need to recognize the language of text in my database.
Is it possible?

Btw, some time ago I have asked to open an issue
