kandi X-RAY | Linq.Translations Summary

Linq.Translations is a C# library typically used in Database applications. Linq.Translations has no bugs, it has no vulnerabilities, it has a Weak Copyleft License and it has low support. You can download it from GitHub.

If you’ve ever written a property on your class and then got annoyed you can’t use your locally-declared property as part of a remote query selection this library is for you. The problem occurs because these properties can’t be translated and sent to the server as they have been compiled into intermediate language (IL) and not LINQ expression trees that are required for translation by IQueryable implementations. There is nothing available in .NET to let us reverse-engineer the IL back into the methods and syntax that would allow us to translate the intended operation into a remote query. This means you end up having to write your query in two parts; firstly the part the server can do, a ToList or AsEnumerable call to force that to happen and bring the intermediate results down to the client, and then the operations that can only be evaluated locally. This can hurt performance if you want to reduce or transform the result set significantly.

Asked 2020-Jan-26 at 14:14

We are using Entity Framework Core 3 with SqlServer Database. Business program needs to create many columns which are not in the Database, due to storage, high querying cost etc. Currently, the team is Copying the whole Database Layer, and Creating whole another layer adding computed members in new entities. Currently taking database layer and applying AutoMapper to new layer. For some reason, this does not seem like optimal method.

In this example, we require computed members called

I haven't tried this, but it is just a thought - How about creating a custom Extension method of DbFunctions?

I have used EF.Functions.Like method which is an implementation of the SQL LIKE operation. On relational databases this is usually directly translated to SQL.
