I cannot get the value from the drop down list and I not sure what's wrong with the declaration and the code.

This is the error message I get :
The INSERT statement conflicted with the FOREIGN KEY constraint "FK_student_Details_lecturer_Details". The conflict occurred in database "SKTM-AAS", table "dbo.lecturer_Details", column 'supervisor_ID'. The statement has been terminated.
I'd really like to know how to do the same thing in my code as going into sql server management studio, clicking on the design of a table, and then from the file menu scrolling to the relationships and disabling the foreign key constraint by selecting no to the 'enforce foreign key constraint'.

I'm getting this error when i'm trying to delete a listboxitem. It's true that an other table (EquipmentStatus) is using the primary key attached to the listboxitem, but how can i delete all the rows that causes this problem? I've seen an example using stored procedure, but i dont understand it, since i haven't really worked with it before:
ALTER TABLE t2
DROP CONSTRAINT FK_t1id
ALTER TABLE t2
ADD CONSTRAINT FK_t1id FOREIGN KEY (t1id) REFERENCES t1 (t1id) ON DELETE
CASCADE
My listbox is using MeetEquip table which p-key is MeetEquip.ID, and the fk-key (which generates the problem) is fk_MeetEquip from EquipmentStatus table.
I am getting the following error The DELETE statement conflicted with the REFERENCE constraint "FK_Person_Country_CountryID_CountryID". The statement has been terminated. I do not want the user to delete the country if there are any FK contrains. Or a better way will be to ask the user if they want to delete the records referencing this "Country".

The INSERT statement conflicted with the FOREIGN KEY constraint "FK_ShopCart_Shopper". The conflict occurred in database "DIYERA", table "dbo.Shopper", column 'ShopperID'. The statement has been terminated.

I"m using table adapters here. I tried to use the following in my table adapter:
ALTER TABLE tblAdvanceLInk
DROP FOREIGN KEY FK_tblAdvanceLink_tblLink
DELETE FROM [tblAdvanceLink] WHERE WebsiteID=@WebsiteID
The DELETE statement conflicted with the REFERENCE constraint "FK_tblAdvanceLink_tblLink". The conflict occurred in database "LinkExchanger", table "dbo.tblAdvanceLink", column 'LinkID'. The statement has been terminated
I get the same problem every time. So I read you could do this in a sql query. Why doesn't this work in my tableadapter? Do I have this in the right place? Do I also put this into the other table? (tblLInk) Isn't there a way to just relax ALL constraints so I can delete some rows? I'm deleting rows from both tables which have the corresponding websiteID
I have two tables with a foreign key constraint how can I delete rows from both of them in one transaction? linq to SQL seems to call my deletes in the wrong order. Is there somewhere I can check and make sure the constraint is recognized properly by linq to SQL??
DataContext.OtherImages.DeleteOnSubmit(myOtherImage);
DataContext.Images.DeleteOnSubmit(myImage);
DataContext.SubmitChanges();
The Foreign key constraint is on OtherImages.
I am trying to build the MVC Music Store from ASP.Net, my only problem is that the tutorial is made for asp.net 4.0 C# and mvc2 an i am creating it with asp.net 3.5 VB mvc 1. For now i found out a lot of thing wich will work much better in the new frameworks, but my webhost still doesnt support it, because they have some problemms with PLESK.
Now i have a problem i cant figure out, i cant update data from a dropdown list, in the database using the updatemodel, that are foreign keys. Just all other data wich are not foreign keys and primary keys are updateable. These are automaticly created in the sql entity model.
Here is my code.

I have a table with three fields, User, City and Country, where exactly one of the fields must be non-NULL at all times. Can I use an SQL constraint for this or should I rethink what I'm doing?
The scenario is that my database should contain documents that can be attached to users, cities or countries. So a row in this table contains exactly one document for either a user, a city or a country. However, one should be able to search for all documents as well, regardless of what entity it has been "attached" to.
The reason I'm not using three different tables instead is that I want to avoid having to JOIN the three tables when searching for documents in all of the three places. I'm imagining that the kind of denormalization I'm attempting to use here will improve performance.
I have tables two tables, the "book" and the "author", a book can have many authors and vice versa, so there is an intermediate table called "book_author" with two columns as foreign key for those two primary keys

I'm trying to edit the book details and also its author using the entity date model, The controller class method

I can only update the book table, but not author that the book has or the book_author, I'm new to asp.net, I can't easily find a tutorial on this issue, I think the logic is to delete the author of the book first and then add the author for that book, but I don't know exactly about that linq and C# code.

let say i have 2 table (PARENT and STUDENT table)
the structure for both table are
STUDENT
PARENT
student_id (PK) parent_id (PK)
student_parent (FK) parent_status (the value is either ACTIVE OR INACTIVE)
- parent_id is refer by STUDENT table as a foreign key
- now i want to inactive the status for parent
- i want my system pop out a message something like "The parent you want to inactive is refer by a student, inactive is not allow"
- is it any constraint in SQL Server 2005 to help me check whether parent it is refer by student table? The concept i want to use is something like delete constraint in SQL Server 2005 mean it is not allow to delete a person who is refer by a student in STUDENT table.
i have a bizar situation, i have a SSIS package which imports records from a flatfile.First i get rid of all the double records, so I keep only unique records before I put them into the desired table.I have put a dataviewer on the flow and notice that there are no duplicate records, and though the SSIS package fails with a violoation of a promary key constraint.Hs anyone seen this before? It is really strange.

I have a SQL Server 2000 table with 7 columns and would like to add a constraint that prevents a row being added with the same value for both Col2 and Col3.
So, for example, if Col2 = 205 and Col3 = 5, then the constraint should prevent inserting another row with the values for Col2 = 205 and Col3 = 5.
The following is an example of what I would like to prevent:
Col1 Col2 Col3 Col4 Col5 Col6
1 205 5 1 1 1
2 205 5 0 0 0

I have two tables, which is table 'A' and table 'B'. Table B contains a foreign key that is referenced to table 'A'. The question now is, could I used an option in my project in visual studio an 'Others specify'? I believed that it's not possible, isn't it?If I have a selection that is bound to a datasource then is it possible to make an option 'Others specify' without adding the specified value to the database, which in turn would not have a unique ID? Table B contains the table A ID PK field, and all values from table A to table B should contain a unique ID.
