Entity Framework Error 3002 Problem In Mapping Fragments
helping each other. Join them; it only takes a minute: Sign up Error 3033: Prblm in mapping fragments:EntitySets 'Entity1' and 'Entity2' are both mapped to table 'Addresses'. Their primary keys may collide up vote 0 down vote favorite Context. I want to separate a shipping table into two tables, the first one for general data about the shipping entity framework error 26 - error locating server/instance specified that are most frequently used and in the second table to store the pickup and destination addresses in different records with a selector field RecordType, in order to retrieve the addresses information only when is required. For that purpose, I created three entities, the entity Move for the shipping general information, the entity pick up address and the entity destination address, the last two entities have an additional field "address type" to distinguish which is pickup and which is destination. With the mapping details screen in the model I mapped both entities, the PickupAddress and DestinationAddress to the same table MoveAddresses, PickupAddress with codition recordtype =”P” and DestinationAddress with condition recordtype = “D”. When I rebuild the datalayer solution I got the following errors Error 2 Error 3032: Problem in mapping fragments starting at line 625:Condition member 'MoveAddresses.AddressType' with a condition other than 'IsNull=False' is mapped. Either remove the condition on DestinationAddresses.AddressType or remove it from the mapping. Error 4 Error 3033: Problem in mapping fragments starting at line 64

But http://stackoverflow.com/questions/18410792/error-3033-prblm-in-mapping-fragmentsentitysets-entity1-and-entity2-are-bo now I have run into a problem. I have a generic table called message and another which is called emailmessage which is link to message in a one-to-zero-or-one relationship. This emailmessage table has more type specifiec data link To,CC,BCC and so on. So in my entity model I created a EMAIL entity which maps to both message and emailmessage. This works 100%. Now I want to add a new table smsMessage https://social.msdn.microsoft.com/Forums/en-US/89af4891-af1d-4d3b-8695-df31f7805c82/error-3033-problem-in-mapping-fragment-their-primary-keys-may-collide?forum=adodotnetentityframework (with the same relationship) and create a entity SMS which also maps to message and smsMessage. But as soon as I create this I get the following error: "Error 3033: Problem in Mapping Fragment starting at line 1002: EntitySets 'EmailMessageSet' and 'SMSMessageSet' are both mapped to table 'Message'. Their Primary Keys may collide." I am using .Net 4 Beta and ADO.Net Entity Framework 4 CPT. I read somwhere EF 4 might support this (Inheritence form multiple tables, by two diffenrent entities), so thats why I am using .Net 4 Beta and EF 4 CPT. But this still doesn't allow this to work. This is the only error I get. Can any one please help me? I will later have to add even more message types lik "IM","MMS".... So we want the generic message table to stay there and not split it all out. I can get arround this by changing my DB design, but this is not optimal for us. Any advice, please? Thanx in advance.

D JamesApril 6, 20095 0 0 0 Background and Motivation: In my last post on EF Jargon I introduced the concept of Relationship Span. If you remember Relationship Span is basically responsible for compensating for the lack of Foreign Key properties* in your Entity. Relationship Span for an https://blogs.msdn.microsoft.com/alexj/2009/04/06/tip-11-how-to-avoid-relationship-span/ Entity, lets say StaffMember, insures that the Entity Framework knows the EntityKeys of the http://blogs.msmvps.com/kevinmcneish/2009/05/18/entity-framework-quot-problem-in-mapping-fragments-quot-error/ other Entities that the StaffMember has 0..1 relationship with (for example DisciplineHistory). These EntityKeys are important because without them the Entity Framework doesn’t know how to delete or update the StaffMember (See Tips 7 & 9 for more information on this concept). Now usually a 0..1 type of relationship is established in the database by having entity framework an FK in the StaffMember table pointing to the target DisciplineHistory table. In this situation Relationship Span can pull the EntityKey for the DisciplineHistory pretty cheaply, because we can do ‘join elimination'. Now no two databases are the same though, and it entirely possible to model this same relationship completely differently: you could put the FK in the DisciplineHistory table. One way to do this is make the PK of entity framework error the related DisciplineHistory table the same as the PK of the StaffMember, i.e. the PK is the FK. In fact this is the only way, that the EF supports, in which you have a 1 to 0..1 relationship that is enforced in the database. This approach is mostly commonly used when modeling additional ‘Aspects' of an Entity in the database. In these situations Relationship Span is a little more costly, because the Entity Framework is either not smart enough to do join elimination or it just isn't possible (both are possible). If you extrapolate this situation further so that there are many entities related via 0..1 relationships (for example StaffMember has many ‘Aspects' like SalaryHistory, DisciplineHistory, AuditLog and BIO etc) then you easily end up in a place where doing a simple query for a StaffMember ends up being very costly, purely because of the cost of doing the Relationship Span. The obvious question is… How do you avoid Relationship Span? Well it is very very easy. You simply do a no-tracking query: var source = ctx.Staff;source.MergeOption == MergeOption.NoTracking;var staff = (from s insource where s.ID == 12 select s).First(); And the resulting query won’t “span” in information about all the related SalaryHistory, DisciplineHistory etc. Unfortunately the res
add another entity that is related in the database to the first entity, Visual Studio will give you a "Problem in Mapping Fragments" error. For example, if you add a Northwind database Orders table using the EDM Update Wizard, it produces an entity that looks has an EmployeeID property that corresponds to the EmployeeID foreign key column of the Orders table. Next, if you add a Northwind database Employees table using the EDM Update Wizard, an Employees property gets added to the bottom of the Orders entity under Navigation Properties and a relationship between the Orders and Employees entities is shown on the diagram. However, there is still an EmployeeID property on the Orders entity. This is what causes the "Problem in Mapping Fragments" error. In order to get around this error, you can simply remove the redundant EmployeeID property from the Orders entity by right-clicking it in the designer and selecting Delete from the shortcut menu.
