Dapper.Contrib - Support for composite keys in Get method

[renanmt]

Hello guys.

I changed a bit the implementation of the Get method so it can also work with composite keys. I have a few tables with this design and it always annoyed me the fact that Update, Insert and Delete supported them but I had to write custom queries when I wanted to retrieve records from database.

The method still works the same way it was defined before.

var regularKey = connection.Get<RegularKey>(1);

But now also supports operations like this:

var keytest11 = connection.Get<KeyTest>(new KeyTest { Id1 = 1, Id2 = 2 });
var keytest12 = connection.Get<KeyTest>(new { id1 = 1, id2 = 2 });
var keytest21 = connection.Get<KeyTest>(new { Id1 = 2, Id2 = 1 });
var singleKey1 = connection.Get<SingleKey>(1);
var singleKey2 = connection.Get<SingleKey>(new { myKey = 2 });

I was also able to optimize Update and Delete methods a bit by using a new method to retrieve all keys.

For your appreciation and code review.

Cheers

.< Wish this one would have been merged in, I need composite keys in my .net core application.

It's been a year and half since I proposed this quite simple change to allow multiple keys on Get method.
All other methods (Insert, Update, Delete) already support multiple keys.

Hi @NickCraver
Do you want me to redo this in the current state of the branch so we can just see it merged soon?
Cause waiting for v2 seems to be not quite realistic anymore.

I am sad this never came true... @renanmt are you still somehow on this or did you give up yet?

Hi @SwissMaWi , I'm suffering from serious lack of time to look into this. I will try my best to get back to it next month, meanwhile, I'm attaching my current working versions. You don't need to install Contrib if you just place this files in your application, since they are basically static helpers.

I will try to fix. It's been almost 5 years and still not supported in Contrib.
Hold my beer. 🍺

Because of the really old PR done in a branch that doesn't even exist anymore I found it a lot easier if I tried to re-implement it in a new branch from "main".

Here's the link to the new PR #1614.

This one can be defined as DEPRECATED.
