LINQ to DB VS SQLProvider

Before checking this out, people might want to take a look through the issues and pull requests of which there are 500+ and 50+ respectively [1]. I was really optimistic about this project and it was headed in a great direction, but it's not in a production ready state, and it seems that the main guy behind it has decided to move onto other things. It's been about a year since there was any significant activity.

I just mention this because a lot of these little issues might only become more apparent after integrating the db into your project and so it can be a bit annoying. I ended up swapping to Linq2DB [1]. It's something, more or less, similar offering an ORM/LINQ type system as well as the ability to also use direct SQL if desired. But the neat thing is that it also uses a standardized API for the LINQ query language, so you can do things like swap from SQLite to PostgreSQL in one* line of code, so long as you're not using any provider specific extensions.

I had a positive experience with Linq2db? https://github.com/linq2db/linq2db

I mention because I had something of the opposite experience with it. It not only ended up yielding the correct queries, but I saw a significant increase in performance. And the neat thing about it, beyond ORM and linq-to-sql, is a common interface amongst providers - so you can do things like swap from SQLite to Postgres with 1 line* of code, so long as you're not using provider specific extensions.

Temporary tables are covered by linq2db. But better to show Stored Proc maybe your final query just needs several CTE which also supported by linq2db.

My learning path was supporting linq2db, not short way. StackOverflow was original source to find something like, how to do if operator in Expression Tree, how to throw exception in Expression Tree, how to build dynamic filter, ect.

Checkout linq2db No need for Dapper or EF with this library. I wouldn't want to miss it.

Why not linq2db? Faster than Dapper and has LINQ support.

Probably you can understand why linq2db was born 15 years ago

As others have mentioned, I think linq2db comes closest to this.

For completeness, there is also the SqlDataProvider, which I only tried out a little years ago, before composibility was baked in. Worth a look.

Have you heard of type providers? https://fsprojects.github.io/SQLProvider/ I think this library might be what you are looking for

Database: SQL or Event Store. If SQL, One of https://fsprojects.github.io/SQLProvider/, https://github.com/Dzoukr/Dapper.FSharp or https://github.com/SQLStreamStore/SQLStreamStore

One of the more popular Type Providers I used is the SQL Provider, but even it has severe limitations when it comes to .NET Core.

There was a wave of popularity in 2017 as well. I used to work on it full time back then, and enjoyed it a lot. The SQLProvider [0] and other type providers like it are super impressive!

(1) F# Type Providers still blow my mind.

Strongly typed SQL/XML/CSV/JSON without boilerplate is a massive leap forward, and it's a shame that it hasn't caught on.

So when I clone a typical open source F# project from GitHub (e.g. SQLProvider, to pick a recent one that I wrestled with), I'm often at a loss how to build and debug the thing. I've figured out that running build.cmd is usually a good place to start, but then what? Can I still open the .sln in Visual Studio and build/debug it there?
