URGENT!! Need help regarding primary key!!

Nov 26th, 2008

I have converted around 395 Excel survey forms to MS SQl database with that many tables. Well, I run a script to assign a primary key on all the tables on my database.First I set the column property to NOT NULL and then i assign the primary key to it. I assign the primary key to a column called 'FPC_Code'. This column contains values such as, _C2348787, _C567489 etc etc......Well, my problem is that THE SECOND I ASSIGN THE PRIMARY KEY TO ALL THE TABLES THEY GET SORTED WRT THE FPC_Code column. I dont want this sorting to take place. I need it to remain unsorted as they are survey forms and would like to preserve the order. I am running out of time and i seriously need help. This is the script I run on all the tables on my database.
