Anthony writes "I love your website guys. I sure hate to cop out on this one, but I am a bit stumped as to the most logical way of changing the order of sequential numbers using either a trigger or a stored procedure.

For example, I have a table like this:


primary_key  group_order
-----------  -----------
    10            1
    20            2
    30            3
    40            4
    50            5

I would like to change primary_key (40) to group_order (2) using

(UPDATE tbl_example SET group_order=2 WHERE primary_key=40)

so that the table ends up looking like this:


primary_key  group_order
-----------  -----------
    10            1
    40            2
    20            3
    40            4
    50            5

It looks like a cascade of some sort could do the trick, but everything I have tried looks like way too much code for something that seems so simple. Do you have any suggestions?

Btw... I am using SQL Server 2000 (SP3)

Thanks,

-Tony"
