Interesting Carlos, I will put that on my list to look into.

My use case is to return a single recordset and a single paramater (most common usuage - retrieve x number of records for something and return the total number of rows so the paging control can format). I'll make an enhancement request in a mo.

 

So I guess returning 2 recordsets in a dataset will be the easiest for now..

Michael? I was hoping you would have tried this on DAL+?

I am not able to imagine a situation where you could not achieve the desired result by making an extra call to the database and passing all the required paramters to obtain the value you need.

Of course I'm using Linq now and I have marked my DAL+ tutorials as outdated.

Yes, I was using 2 calls to get around it but obviously 1 is better than 2 for scalability/efficiency...  It would be nice if the core could review the DAL area and come up with a best practise or standard - I have never had 1 customer in 3 years who has used any other DB than SQL with my modules.

I understand your point. HOwever, the DAL is basically "What the DotNetNuke Core uses". It is actually only offered as a reccomendation not a requirement for module developer's. So basically the DAL would only be changed if it did not work for the Core for some reason.

The DAL+ was just a "here is a fast easy way but it has limitations". Now Both these technologies are years old. We now have Linq to SQL and with DNNLinqToSqlAdapter you can have Linq to SQL that works with the DNN Core componants.

I think the next move for the Core will be Linq to Entities once it gets stabalized. It really is not worth the effort to fix any issues with DAL+.

Ok, good to know, I'll use the DAL for Output params and the DAL+ where it makes sense, and keep an eye on Linq - from what I understand this is only available in .NET 3.5 so as a module vendor I would probably need to support the old DAL for a lot longer (I use EntitySpaces on my custom modules).
