View 2 RepliesSQL Server :: Adding Rows To Multiple Primary Keyed Tables?
Jul 27, 2010I am accessing rows in an SQL database table based upon the contents of 2 Primary key columns. But, I cannot insert new rows in the table when the content in one of the new Primary key columns already exists in another row. I get an error message that says: "Violation of PRIMARY KEY constraint 'PK_ReferendumVoters'. Cannot insert duplicate key in object 'dbo.ReferendumVoters'. The statement has been terminated."
The reason why this error is occurring is because I first stored "Referendum 1" in one column along with "me" in the second column of a new row for a "ReferendumVoters" table. Then, I attempted to insert a new row with the same "Referendum 1" string in the first column along with a different name in the second column. But, it will not let me do this even though I created a new index that defines the two columns as unique. Is there any way that will enable me to do this?
SQL Server :: Inserting Null Value Into Foreign Key Table With Allow Null Enabled?
Oct 2, 2010I have 2 table Table A, Table B.
Table A - Parent Table
ID - Uniqueidentifier not null(PK)
Table B -Child Table
ID - uniqueidentifier null(FK, TableA)
I have a stored procedure to insert data into Table B, but when I tried to insert a null value into column ID of table B, this error came up:
The INSERT statement conflicted with the FOREIGN KEY constraint "FK_tableB_tableA". The conflict occurred in database "database name", table "table A", column 'ID'.
The statement has been terminated.
The insert statement in asp.net is like so:
sqlcommand.parameter.add(New Sqlparameter("ID", Nothing))
I am guessing adding nothing to the null value column is the problem, but i don't know how to fix it... The INSERT statement conflicted with the FOREIGN KEY constraint "FK_tableB_tableA". The conflict occurred in database "database name", table "table A", column 'ID'.

Add A Foreign Key From A Table In Another Database Connection?
Jan 21, 2011I have set up a ASP.net MVC application which uses the default forms authentication. It uses the ASPNETDB.mdf like shown here:
I then set up another database connection which is similar to the NerdDinner.mdf file above.

Dynamic Data Foreign Key Table Display Name?
Nov 26, 2010I have these two tables in my diagram:
the 1st:
PAR_TipiDocumento with
idTipoDocumento PK
idClasseDocumento
[...]
the 2nd:
PAR_ClassiDocumento with
idClasseDocumento PK
[...]
and a foreing key FK_PAR_TipiDocumento_PAR_ClassiDocumento from PAR_TipiDocumento.idClasseDocumentoto PAR_ClassiDocumento.idClasseDocumento.
This is my .cs code for the metadata:
[MetadataType(typeof(PAR_TipiDocumento_Metadata))]
[DisplayName("Tipi Documento")]
public partial class PAR_TipiDocumento[code]....
The problem is that in the Dynamic Data generated pages I correctly see all the display names "Tipi Documento" except for the header row of the PAR_ClassiDocumento table where I have "PAR_TipiDocumentos" (the plural generated by LINQ to SQL). The values under this column are correctly rendered as links to the PAR_TipiDocumento table with the right display name ("View Tipi Documento").
How can I change the Display Name of that "PAR_TipiDocumentos"?

View 2 RepliesSelect Query In LINQ Based On Foreign Table
Mar 2, 2011I have 2 Tables , OrderDetails and Requests In my LINQ to SQL dbml file. OrderDetailsID is a foreign key in Requests Table. I want to write the query to get the sum of UnitCost from OrderDetails based on OrderId. And If there is a row in Requests Table for each OrderDetailsID, and the Requests.Last.RequestType="Refund" I want to reduce the total refund amount from the main sum otherwise If there is no row based on OrderDetailsID, add to sum. Here is the way I implement that. I am looking to prevent using "For each".
iRefund = (From od1 In dc.OrderDetails _
Where od1.OrderID =1 _
Select od1.UnitCost).Sum
Dim objOrderDetails = (From od1 In dc.OrderDetails _
Where od1.OrderID =1 _
Select od1)
For Each OrderDetail As ORM.Entities.OrderDetail In objOrderDetails
If Not OrderDetail.Requests Is Nothing Then
IF OrderDetail.Requests.Last.RequestType="Refund" Then
iRefund -= OrderDetail.UnitCost
End If
End If

Security :: Link Aspnet_users To Table With UserID As Foreign Key?
Aug 10, 2010Perhaps this is a simpler VS9 question, but I want to link a SQLServer table with additional user data to the standard SQLServer membership table using the GUID userID as a foreign key. I go into design mode of my table, right-click on relationships, and click add in the dialog. but the left hand column shows me only the tables in my database. How do I get it to show the tables in the ASPNETDB.MDF database? I went through the tutorial (http://www.asp.net/learn/security/tutorial-08-cs.aspx), but it seems to magically appear in there without explanation.

View 1 RepliesMVC :: Creating Table Records With Foreign Key Constraints / Separate Controllers?
Oct 3, 2010I have multiple tables that are all linked back to a central table with foreign keys. I want to be able to create a new record in table 2, but I'm having trouble because I don't know how to create a new instance of table 2's record while referencing the ID of the record it will be tied to.
EXAMPLE:
Database: Collection
Table: Collection Field 1: id Field 2: name
Table: Book Field 1: collectionId Field 2: id Field 3: name
Now, I don't want to be able to create a book without setting it's collectionID, but I can't figure out how this should be divided in the controllers/views.
Should Book have a controller separate from Collection, or should the Collection controller have a createBook method, separate from it's own create method?
I want to call the createBook method (from it's own controller, or the Collection controller) from the Collection Details view.
When I invoke the create method of Book, how do I create a new Book that is instantiated with the collectionId set from the details view of the Collection item that was listed in the details view?
I should point out, I'm using the entity framework for my model, and I'm definitely new to this.
