New Post: join in LinqToCRM not working

Bernybon — Wed, 05 Oct 2011 19:45:45 GMT

I get the error :

Error 1 The type of one of the expressions in the join clause is incorrect. Type inference failed in the call to 'Join'. C:\Users\Administrator\Desktop\DEV_VM\TestChap2\ConsoleApplication1\Program.cs 127 26 ConsoleApplication1

But my code is this one:

var queryx = from c in orgContext.ContactSet
                         join a in orgContext.AccountSet
                         on c.ContactId equals a.PrimaryContactId
                         select new { contact_name = c.FullName, account_name = a.Name };
            foreach (var c in queryx)
            {
                Console.WriteLine(c.account_name + c.contact_name);
            }

Anyone would have an idea ?

New Post: Problems in Many to Many

Gamalof — Sun, 15 Aug 2010 08:37:21 GMT

Hi,

I always get this error MSG "Server was unable to process request" whenever i try to make a query against the generated ManyToMany class. My Query is simple as it can be, it looks like

from b in CrmQueryProvider.Linq<Bridge>()
select b;

Where Bridge is the name of the generated class in the ManyToMany.cs

More information:

The problem comes from the Fetch method in CrmWebService.cs class.

Any suggestions ?

Thanks so much

That's interesting, Martin. I did not realise that filtering is done client-side with the MS SDK Linq provider. Also, according to this page:http://msdn.microsoft.com/en-us/library/ff681573(v=MSDN.10).aspx the provider supports joins. You mention that it doesn't support linked entities, can you be more specific?

Why are you killing the project? Because of the cheap LINQ provider in the SDK? The one that cannot be used in plugins? The one that fetches a shitload of records to the client to check conditions there? The one that isn't able to use FetchXML to work with Linked Entity's? The one of which the caching mechanism sucks?

I suggest you continue this project ;-)

Wow, sorry to hear you are killing the project. On the other hand though it is great that Microsoft supports Linq now. Thanks for the info.

Hi Pete, Microsoft has released a linq query provider with the CRM SDK. I recommend you check that out: http://friism.com/linqtocrm-obsoleted

Does anyone know when Linq to CRM is scheduled to be released and come out of beta?

Thanks,

Selecting out of joined entities come to mind at least.

@praty It's a valid point, but I think the FetchXML stuff that can't be mapped to QueryExpression is pretty marginal ("Average" anyone?). Do you have example of FetchXML features you need that aren't doable with QueryExpression?

"It should be emphasised that the LINQ query ultimately maps down to a QueryExpression, and hence you are as limited in the scope of queries as you currently are."

As QueryExpressions don't support everything that FetchXML does the MS code (haven't tried) could be more limited in features.

Thanks for the heads-up, I'll update the frontpage with a link.

Microsoft has published a full LINQ-to-CRM query provider in the latest SDK release (4.0.0012). The new customer portal also also uses the new query provider.

Probably a bug in LINQtoCRM. Please file an issue with the exception back trace.

I'm wondering what you are planning to do with {a1, a2}. Some more code might help so someone can gauge your intent.

New Post: Multiple Conditions in a Where Clause vs. Multiple Where Clauses

12055 — Thu, 11 Mar 2010 02:28:41 GMT

Wondering why

from x in crm.Linq<t>() where !x.foo1.IsNull && !x.foo2.IsNull select x

Throws an exception while the following works without issue:

from x in crm.Linq<t>() where !x.foo1.IsNull where !x.foo2.IsNull select x

Is this a limitation within LINQtoCRM or am I wrong that these statements are equivalent?

No Worries, I love the implementation so fare and this is the first show stopper I have come across.

I love reducing code and with your work I came down from 1100 to 300 lines...

Thank you!!

Ok, so I will implement a fix and test it and then once I am done I will submit the changes so you can merge it?
