How To Change Field (or column) order through script

Hello Experts.
I have to go through a huge database and change the Primary Key field to always be the first field in the table (the database designers before me didn't know it was important to be that way)
I am wondering - is there any way I can Alter the table and change the field order without losing data?
What would such script be?
I know I can do it manually in Management Studio, but that is not what I am looking for.

I don't know that it is important to be that way.  Why?

I have tested it and when selecting large amounts of data, and having the primary key being the first field the result comes back significantly faster that way.

So, do you know of a way I can change the order by using script?

No, I'm afraid I don't.

The order of the columns has no effect on the speed with which the are retrieved.  Please post the table schema and the query you claim is dependent on column order.  Please include any indexes defined on the table.

I am afraid, all things being equal that is a perception problem on your part.

You cannot do that without rebuilding the table.  This involves dropping any FOREIGN KEYS and then recreating them.  Incidentally, this is how the SSMS table designer does it.
