Hello everybody,

I am sakshi.
I am creating a c#.net windows based project with ms sql database.
I am using delete query which is working well.
but my problem is------
I want to re-arrange the datatable after deletion.
As I have rows having id 1,2,3,4,5,6 which is not the primary key.
after delting 1,5 row,it becomes 2,3,4,6.
I want that it should be 1,2,3,4 means remaining rows should be re-arrange staring from 1.

IS there any other way to it without looping..

Please reply.

Thanks a lot

Solution 1

If this is not a primary key, the simplest way to do this would be to run a loop to update this key after every delete.

After Delete from your table just execute below script it will re arrange your ID

CREATE PROCEDURE INSERTID_FDA_UNII_SUBSET
AS

BEGIN
Declare @ID int
Declare @MaxID int
Declare @OtherVal nvarchar(20)

DECLARE UserDet_cursor CURSOR FOR 
	SELECT Id,Uniicode FROM Table1
open UserDet_cursor
Set @MaxID = 1
FETCH NEXT FROM UserDet_cursor into @ID,@OtherVal
while @@FETCH_STATUS =0
BEGIN
	update Table1 set ID = @MaxID where OtherVal= @OtherVal and ID = @ID
	
	FETCH NEXT FROM UserDet_cursor into @ID,@OtherVal
END
CLOSE UserDet_cursor
DEALLOCATE UserDet_cursor
END
