I have 3 tables: Pendants PendantAccessories PartsData Basically #1 and 2 are used for product selection,

so #1 has a "Number of Buttons" property and other options. #2 has fields like "Cable Type" etc. The third table contains property information for all of our parts, such as what plant it's manufactured in, it's weight etc. What I'm trying to do is set up an association between #1 and #3 and also between #2 and #3. The PK in all 3 tables is the PartNumber. I set it up between #2 and 3 by going into Mapping Details
Entity Framework 4 Transactionscope
and adding a Maps to PartsData and mapping the columns. Everything worked good. I then tried the same thing between #1 and 3. However, now when I compile I get "Error 3033: Problem in Mapping Fragment starting at line 713: EntitySets 'pendants' and 'pendantAccessories' are both mapped to the table 'PartsData'. Their Primary Keys may collide." Does anyone know what I'm doing wrong here? .net entity-framework share|improve this question asked Apr 13 '10 at 14:57 taylonr 8,40812455 add a comment| 1 Answer 1 active oldest votes up vote 1 down vote accepted Not sure what I did wrong, but I found a work around, which is actually what I probably should have done in the first place. I thought I had defined FKs in the DB, but, at least for these 3 tables, I didn't. So I defined them, removed my model and re-created it (since Update from Database doesn't seem to work.) Now it's all up and running. share|improve this answer answered Apr 13 '10 at 16:11 taylonr 8,40812455 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google Sign up using Facebook Sign up using Email and Password Post as a guest Name Email Post as a guest Name Email discard By posting your answer, you agree to the privacy policy and terms of service.

But 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 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 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 (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 ev

How entity framework I can config DbContext to create database on Sql Server? the error is : Login failed for user 'x' Thanks ErikEJ commented Sep 5, 2015 Did you ask EF to create the database? (There is no "magic" any more) - http://ef.readthedocs.org/en/latest/getting-started/full-dotnet.html#create-your-database mikeandersun commented Sep 5, 2015 Is there any automatic database creation ? at least for development environment. With build before entity framework 4 15564 the database was created automatically. ErikEJ commented Sep 5, 2015 You can use Database.EnsureDeleted(); Database.EnsureCreated(); mikeandersun commented Sep 5, 2015 This way just create database with no any table. I need a way to create database from model. ErikEJ commented Sep 5, 2015 Have you tried it? https://github.com/ErikEJ/EntityFramework7.SqlServerCompact/blob/master/test/EntityFramework.SqlServerCompact.FunctionalTests/BasicEndToEndScenarioForIdentity.cs ? mikeandersun commented Sep 5, 2015 The error was I override OnConfiguring on my dbcontext and forgot to call base.OnConfiguring(optionsBuilder); Thanks for your time. mikeandersun closed this Sep 5, 2015 aspnet member divega commented Sep 5, 2015 @mikeandersun If you inherit directly from DbContext then base.OnConfiguring(...) does absolutely nothing. On the other hand in EF7 we have moved away from automatically creating databases on first run. That is intentional. While automatic creation is nice for fast prototyping and demos, it makes things more complicated down the road. mikeandersun commented Sep 6, 2015 @divega In my opinion automatic database creation is very nice for developing phase of a project. If this done by automatic migrations creation/apply by the tooling(VS.NET) of from code it is better. ErikEJ commented Sep 6, 2015 If (IsRunningFromVisualStudio()) { Database.Ensu
I'm trying to do I would think would be ridiculously simple but I'm pulling my hair out and have spent days trying to figure it out.I have an Address and AddressType table which are joined on addressTypeID. There are 2 AddressTypes, "Billing" and "Shipping". I'd like to be able to create a custom entity for both Billing and Shipping. I would have thought I could just inherit from the Address entity and add a condition to that to retrieve the correct type but its not as simple as that.I do not want to remove the navigation properties or fields from these existing entities so that we can dive into those pre-existing entities if need be.The goal is to create custom entities that contain fields from other entities based on certian criteria... almost like what a view does for SQL server. Literally all of the examples I found on the internet are not clear on how to do this.What I have right now is Table per Concrete type (I believe). Everytime I try to do this vs yells at me telling me that things arent mapped etc... and I map them then get a new error message. Are there any good tuturials out there that are clear? I'd rather not dive into the ssdl, etc since those would get overwritten when I rebuild my model.lazy loading is disabled... thats how I want it.Why can't I just create a new entity, copy and paste the fields and set the table mapping? I created a new entity called BillingAddress, copied the fields from Address and set the table mapping.... then I get the error:Error 297 Error 3033: Problem in mapping fragments starting at line 4525:EntitySets 'BillingAddresses' and 'Addresses' are both mapped to table 'Address'. Their primary keys may collide.I also tried inheriting from the Address table.... error: must specify mapping fror all types in Set Addresses .net entity-framework entities share|improve this question edited Jun 28 '10 at 22:13 asked Jun 28 '10 at 22:06 Chris Klepeis 5,0561062
