Primay key is one type of constraints.There should be a way to differentiate Primary keys in datbase.
For example if i have another table called Dept with a primary key.
if we don't specify primary key name in your table .there will be a conflict in database system.
think that database has a SQL parser to understand give SQL statements.
correct me if i am wrong.I have no idean in mysql.
I’ve looked at a lot of different solutions, and in my humble opinion Aspose is the way to go. Here’s the link: http://aspose.com
