DataSource Controls :: Change The Primary Key Value?

Jan 4, 2010

Let'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.

DataSource Controls :: Returning Primary Key Of New Database Row

Jul 9, 2010

In 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.

DataSource Controls :: How To Get The Primary Key Of The Newly Inserted Record

May 10, 2010

I am using a FormView to populate data, then inserting it using a LinqDataSource. The primary key is an autoincrementing identity. I'd like to handle the ItemInserted event to update some other tables, but I cannot find how to get the primary key of the newly inserted record. The insert happens fine, but nothing for the PK.

I realize I can change to using a SPROC, or change to creating the new row and doing the insert myself, but I'd prefer to continue with the LinqDataSource's automatic insert.

How can I get the PK?

DataSource Controls :: Insert Sequential Numbers Into A Primary Key Column Using A Script?

Jan 29, 2010

I need to insert multiple records using a script.

My table is

Region
(
ID int,
Name varchar(50),
Description varchar(51)
)

One thing I can use is to retrieve the max(ID) from region and store it in a variable and increment the variable sequentially and insert. But, if any other user inserts a record while I am executing this script then max(id) might clash with the id inserted with other user causing my script to fail.

Is there any other option to insert record sequentially base on the highest number in the table.

Forms Data Controls :: Compare Integer Value To Primary Keys Of A Detailsvew Datasource?

Mar 8, 2010

I have a textbox that takes an integer value, and a submit button that when clicked passes the value to a detailsview to display the database record at that index.

What I'd like to do is, when the button is clicked, compare the number to the keys in the detailsview's datasource so that if the record ID doesn't exist, I can display a label telling the user that the ID# doesn't exist.

How would I go about doing this? Is there some sort of compare method for the datakeynames property?
