So with LINQ-to-SQL I know you can update the database from the LINQ objects and update the LINQ objects from the SQL. I am using LINQ's entity framework (a.k.a. LINQ-to-entities) and I can update the entities from the SQL database, but I can't update the database schema by changing the entities. This is frustrating. Is there somethin...
Is there an IBM Driver so we can use Linq to Entity framework to connect to DB2 and generate the DB2 entities on the desinger edmx file? Any links would be greatly appreciated ...
I've been working on training myself in the ways of using nAnt over the past few days, and have stumbled across an issue. During the development process, I've been using the new tools, like Entity Data Model, for database access. When you go to try to build a library/executable that contains the Edmx product, you cannot embed the requi...
When I create a new diagram and "Update model from database", the StoreGeneratedPattern attribute gets added to some primary key properties, but not all of them. What criteria does the designer use to decide whether to add this or not? ...
We have a big (and growing!) database. We're trying to not have to build the models by hand, and we found this EdmGen2 which is supposed to build our EDMX entity models for us. Since we have such a big database we'd like to not have all of our tables in the same Model. We got it all to work, but the generated model has all of our t...
I am having trouble with my Linq2Entities model - I might be missing something obvious here. Here is what I did: Added an EDMX model file Added TableX to the model Went back to SQL Management Studio and updated TableX, changing its primary key Went back to my EDMX file and click "Update Model from Database" TableX updated but incorrec...
I added some tables to my DB, and refreshing the model didn't work. So I deleted my .edmx file completely. I then recreated the model according to my updated DB, but the same tables were still missing. I'm not really sure why, but for some reason it won't load certain tables into the model. I looked at the XML .edmx and the tables ar...
Does any one know if there is kinda implementation/addon for VS 2008 SP1 for pluralization service in entity framework like there is gonna b in vs 2010? example: In database: Entity Order ---OrderId ---CustomerId ---OrderDate Entity Customer ---CustomerId ---Name In EDM: Order.Customer Customer.Orders DataContext.Orde...
Two quick quesitons: Benefits of using EDMLs vs. EDMXs - when would you choose to use one over the other DevArt's Entity Developer vs. Visual Studio's Entity Designer - I know this part of the question may be a bit subjective, so I would rather ask which tool does a better job with entity design I've found that some relations in DevA...
First question to SO, I hope I'm doing this right. ;) Regarding System.Data.Entity.Design.EntityStoreSchemaFilterEntry : I'm looking for some detailed documentation on this class. The MSDN docs have nothing but an indication of what properties exist and their data types. I want to create a well-defined list of filters for EntityStoreS...
Hi All, My question might be little bit different or basic for advanced users here. I have a web application which is customizable by administrators. This means, the admin can add new table schema or edit table columns, add new table columns etc. These changes are mapped to our logical objects (much similar to EDMX) which is publishe...
Hi, I have a db with 5 tables. at the beginning, i've added those tables in, but then decided to remove some due to some relationship compile error. Now, when i want to add them back, i'm opening the edmx file -> update model from database.. -i don't see those tables under add tab, but only under the "refresh" tab. how can i add them ...
so the story is like this. I have a project, called PA.DLL, which have an entity model inside of it (edmx) file. In another project which i'm referencing to the PA.DLL, i copied the connection string that was created (automatically) when creating the edmx file into the main app app.config. however, when i load and run the following l...
When you use the update-edmx feature of visual studio. Your EDMX schema is merged against a database. What Rules Apply to changes merging? UPDATE: looks like new db fields are added to your edmx, modified fields are merged in someway and deleted ones are left in your schema. ...
Hi, I'm using the microsoft EdmGen2 to generate my edmx file from my database. The tool works great, but there is one things missing - it doesn't support function. Is there a way to map all the stored procedures to be functions? Also, if i'm editing it manually, the next time im running this tool, i'm losing all those changes. my ques...
hi, i have an entity-model file (edmx) file which contains few tables and few stored procedures. how can i call those stored procedures that are mapped to functions? i thought it should be trivial, and i do see the mapping in the edmx file, but i can't figure how to use it in the code. here is one mapping example: <Function N...
I'm attempting to convert a class library consisting of 1300 classes into an entity model. My current approach is to reflect on each type and generate the edmx via T4 template, however its getting kinda messy. Is there a better way to generate this? ...
I'm trying to get the entity framework working in medium trust. I've tried splitting the files and using a separate assembly but I seem to have one problem after another. I moved the EDMX to a separate assembly, which causes a single .dll to be outpit to the sites /Bin directory. I'm referencing this as below from web.config. <add name...
I have a sql image type field coming back in an EDM (Entity Data Model) .NET service call. The image field is stored as binary in sql server 2008. However, I'm not sure what is happening to the image data, or what type of encoding. And since the webservices are generated behind the scenes, I can’t figure out if the service is doing somet...
