Nevermind, I figured it out. I had previously dropped the table which should have dropped the constraints with it. But not in this case. I again dropped the table and then dropped the constraint and this allowed me to create the PK.
I am trying to create constraints that will create my pk @ fk. When I run my code I am retuned the following error.
the name PK_ is only a help for you, that you know, that this is a PK ... you can create Primary Key with the suffix pk_ but they are still primary key. Anyway ... naming a primary key with th suffix PK_ is a good idea.
So, the best way to create table with primary keys is
1) create table
2) create primary key (perhaps in the CREATE TABLE statement)
