Thank you for the timely response. I was able to download the 6.x version and it seems to work OK with VS2010 SP1.

My VS version is 10.0.40219.1 SP1Rel

error when trying to update model from database

Hello -

I am using dotConnect for Oracle v. 5.70.190.0 over EF. Recently I tried to add another table to my model (by running the "Update from database" wizard in VS) and got the following exception:

-------
Unable to generate the model because of the following exception: 'An error occurred while executing the command definition. See the inner exception for details.
Can't found Project
'.

-----------------

Could you please let me know how to address this issue?

ArgumentNullException when querying many fields

Here is my scenario:

I have built a WCF Data (oData) service that is using dotConnect for Ora provider, version 5.70.190.0. When I execute a query to a single entity, selecting up to 8 properties, all is well. However, if I add just one more property/column to the list of selects I get the following exception (the type of the newly added property does not seem to make any difference) :

ArgumentNullException: Value cannot be null.Parameter name: value

and here is the stack trace:

at System.Data.Services.WebUtil.CheckArgumentNull[T](T value, String parameterName)
at System.Data.Services.Internal.ProjectedWrapper.set_PropertyNameList(String value)
at lambda_method(Closure , Shaper )
at System.Data.Common.Internal.Materialization.Coordinator`1.ReadNextElement(Shaper shaper)
at System.Data.Common.Internal.Materialization.Shaper`1.SimpleEnumerator.MoveNext()
at System.Data.Services.Internal.ProjectedWrapper.EnumeratorWrapper.MoveNext()
at System.Data.Services.DataService`1.SerializeResponseBody(RequestDescription description, IDataService dataService)
at System.Data.Services.DataService`1.HandleNonBatchRequest(RequestDescription description)
at System.Data.Services.DataService`1.HandleRequest()

I saw forums that mention similar problems, but it was recommended that the users upgrade and I am already using the latest version of the dotConnect for Ora.

Does anyone have any idea where I need to look at?
Is this a known issue?

It appears that the length of the URL is in play here - if I have it under around 180 characters it works, if it is higher than that, not so much.

Many thanks in advance, G.

what was the solution?

Hi - could you please post the actual solution? I am having a very similar problem:

if I use up to a particular number of properties when new-ing up the object, it is all well. However, if I add one more to the list, I get the mentioned exception. Was this resolved ?

Any help is greatly appreciated. G.

license move

Hi guys - I need to move my dev license to a new machine. My questions is : what are the steps to accomplish this? Do I simply install it on the new machine and un-install it from the old one?

Many thanks in advance. G.

OUTER APPLY is not supported by Oracle

Hi all -
I have a very simple case: two entities with 1-to-many relationship (e.g. one company-to-many-employees).
Case1 (works ok): I use Linq2Entities over the compiled DLL containing the model and using the ".Include" syntax I eagerly load the related entities (Employee) just fine.
Case2 (does not work): I expose the model via WCF data service. When I try to eagerly load the related entity on the client (via the ".Expand" method) I get the "OUTER APPLY is not supported by Oracle" exception.

Note - this problem does not occur when the relationship b/w entities is 1-to-1.

Can anyone please shed some light on this for me? Is there a known work-around?

WCF Data Services and EF4.0 with dotConnect to Oracle issue

Here is my situation:

I am using EF4.0 with dotConnect to Oracle and have a simple star schema model. The model is exposed via Wcf Data Service (oData).

I can successfully browse my entities via the web browser. I can find a single entity that I am interested in and using the generated link traverse all related entities.

However, If I create a separate project (say WPF) and attempt to use Linq syntax, I get a NotSupported exception if using the Entity.Expand("RelatedEntity") notation. If I opt for the LoadProperty Method things seem to work.

Can anyone address this issue please?
