View 3 RepliesADO.NET :: Primary And Foreign Key Auto Populate?
Aug 7, 2010In LINQ to SQL, can primary and foreign keys be autopopulated from an associated key?I'm using the asp.net userID assigned by the create user wizard as the primary key/foreign key in several tables. Right now, when a new user is created, their userID shows up in the asp.net tables but not the ones I created. I thought it would be easier if the keys could fill themselves in, like cascade, so as I have the user fill out forms, they would already have a row in the table created and it would be an of an update instead of an insert row.

Jul 29, 2010I have two tables - Advert and Student
adID is the primary key (Advert) and acts as the foreign key for Student
I have two pages, both of which each have a detailsview in insert mode
what I want to achieve is to create a new record in advert.aspx (e.g. adID = 4), then when item is inserted, redirect to page student.aspx (which a student record is created) where the foreign key is the ID from the advert just created (e.g. student.aspx?adID=4).

SQL Server :: Foreign Key On Multiple Tables?
Jan 30, 2011I have four tables namely tblStudent, tblParent, tblEmployee and tblUnwantedVisitor.
tblUnwantedVisitor should get the primary key from the three tables, which is the visitor ID, tblStudent visitor ID starts from 10000, tblEmployee from 20000 and tblEmployee from 30000.
I used foreign key from one to one table only, so I don't know if my approach for the database is wrong or foreign key for multiple tables, which is somehow unlikely, is necessary.
Entity Framework: Substituting Primary Columns For Foreign Key Columns
Jun 30, 2010I've created a new ASP.NET website. I've generated an Entity Data Model from my database and have dropped a entitydatasource and gridview onto my page and wired up the gridview to pull from the entitydatasource. Now I get columns like this: id extension prefix did_flag len ten_id restriction_class_id sfc_id name_display building_id floor room phone_id department_id
In each case where the item is named something_id this reflects a foreign key relationship in the database - and I did choose to have the EDM expose foreign key relationships. I'd like to make it so the gridview pulls in the values for these foreign keys rather than just showing the ID numbers - so, for example, department_id might have a value of "101" right now but it should pull from the department table "Marketing".

View 5 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?

View 2 RepliesDataSource Controls :: Change The Primary Key Value?
Jan 4, 2010Let's say I have a table that holds information about books, with a column called bookid as a primary key with auto increment of 1. When I create a couple of records, it assigns 1 to the first row and 2 to the second row for the bookid column. If I delete the second row and enter another row, even though table now only has 2 records, the primary key column says 1 and 3 for their bookids. Is it possible to change back the bookid of the second record from 3 to 2 or is it just server assigned and can't be changed.

Mar 8, 2011I am using Entity Frameowrk as the ORM. I am new to MVC and trying to develop a samll module as a learning project.
Now I am stuck with an issue for which I can't seem to find out answer on web. The issue is :
I have two tables mapped as entities - Tenant_Definition and Contact
Tenant_Definition { Tenant_ID , Desc, Contact_ID}
Contact {Contact_ID, Company_Name,Company_Address,Person_Name, Person_Phone_Mobile}
My View has to present a form that shows Tenant Desc and Contact related fields. The index view works fine and shows the desired values.
But, the create view isn't working out. In the create view, i am planning to do -
1. creating a new contact entity instance and saving it in db
2. Then creating a new tenant entity instance using the new contact_id and save it to the DB.
However, the code doesn't seem to be inserting any value inside Contacts table. It inserts null value.Below is the code snippet of my Create Controller -

DataSource Controls :: Returning Primary Key Of New Database Row
Jul 9, 2010In my application, users fill out a form to submit a "Job Request" - once they submit the form it is stored as a new row in a table in the Sql database. Each "Job Request" that is submitted is given a "JobID" which is a number and also the primary key of the new row in the database (the number is generated by the database). Once the users hit the "submit" button, I'd like to return the value of the "JobID" (the primary key) so that the user can know what it is. How would I achieve this? In the future, I will have to expand the application so that the users would be able to edit an older "Job Request" and get a similar JobID number (so if before it was 1234, the new one would be 1234-1 or something like that), so this is not simply a matter of searching for the highest number in the primary key field in the table and returning that. I'm using Sql for my database and writing in VB.
