Access foreign key not updating
When this option is selected, the generated entity objects have scalar properties that map to foreign key columns.Foreign key properties allow you to create or modify a relationship without querying for the principal object.Regards, Heikki ----- Original Message ----- From: "Jeremiah Jacks" Sent: Tuesday, July 29, 2003 AM Subject: RE: Error with foreign key constraint when updating Oh sorry...

I am suspecting you printed these from wrong databases.I was trying to disguise my db name with "mydb", heh. Cancel=True, because the following update whould - correctly - give me a "Row not found or changed": Is that (manual update and cancel) a correct way of handling things, or is there a better/more elegant solution?(Sorry for being a bit blunt, I've been staring at this way too long) Thanks I'm implementing a many-to-many editor in ASP.I would probably have gone for something like Flot ID, Item ID and Dep ID. Value 'Database Name tbl Name Prime = Active Sheet. Execute str SQL 'Msg Box " " & str SQL & " " End With Set cnt = Nothing 'Create Table Name [Float Information] tbl Name = Active Sheet.
There are 4 tables and below are the SQL statements that create the Database. When I go to Access the tables look great and I do not get any error messages.
I can only assume that FKs are updated directly by setting the key value?
Background: I'm trying to build my own Many-to-Many for L2S, and it seems that the updating/inserting event is the only place where I can change the relationships without running into a massive amount of problems.
When you include foreign key properties, you can still modify a relationship by updating the reference to the principal object on the dependent or adding a dependent object to a collection on the principal object.
A common way to access references and collections on entities is through navigation properties. The Entity Framework tries to keep references, collections, and foreign key properties in sync.
