Question

I am looking for the best way to update the value I store on the following structure:

Table: Pages

Fields:

1. id (int)
2. bookid (int)
3. pageorder (int)
4. filename (string/varchar)

So I have the book order and a page number. I need to insert a page before the page number I have, lets say 25, and update all the other pages to have 1 added to their pageorder value.

Can I do this without pulling a list and cycling threw it running updates, or is that the best way to go about it?

Thanks!

Answer 1

declare @newpage int
set @newpage = 25
update pages set pageorder = pageorder +1 where pageorder >= @newpage and bookid = @bookid

something like that?
