helium-etl-queries VS LINQ to DB

This is a shortened version of a more detailed article on our blog. We explore how to design and implement an enterprise-level DAL using Linq2Db. The goal is to embed core concerns directly within the data layer itself, ensuring their consistent application without manual enforcement.

There is https://github.com/linq2db/linq2db which is LINQ to SQL reincarnated.

Of course there's EF Core too.

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.
