Npgsql is the .NET data provider for Postgresql. It allows any program developed for .NET framework to access a Postgresql database server. It is implemented in 100% C# code. Postgresql versions since 9.0 are officially supported, others may work.
jsonb_path_match
method, how would that look in c#? JsonbPathMatch(object, string, string)
or would it be more like JsonbPathMatch(object, string, object)
and the second object
param gets translated aswell? i.e. we created a custom method translator in the form of JsonbPathMatch(object, string, string)
and are looking to upstream it
.Where(p => p.JsonField, "exists($[*] ? (@.id == $id && @.value == $value))", JsonSerializer.SerializeObject())
Hi everyone, a newbie question about Npsql 5.0.0
I'm following this tutorial here: http://zetcode.com/csharp/postgresql/ and just using the most basic example where I have a hardcoded connection string and want to print out the version of my local postgres DB.
The program runs successfully if I use 5.0.0-preview1
but fails when I use 5.0.0
with this "Unhandled exception. System.TypeInitializationException: The type initializer for 'Npgsql.TypeMapping.GlobalTypeMapper' threw an exception. ---> System.Reflection.ReflectionTypeLoadException: Unable to load one or more of the requested types." error - could someone please point me in the right direction? How should I configure my connection string for Npsql 5.0.0? thank you very much!
Hey there. We've updated from EFCore 2.6 -> 3.1 -> 5.0 recently (mid update to 3.1 we decided to go to 5.0 directly, so till running 2.6 in prod) and in the jump from 3.1 -> 5.0, I got this diff in my OnModelCreating (DB-first approach)
I tried google for info but didn't find anything helpful. Anyone that could fill me in on what this means? Anything I need to test somehow on the prod server?
