What does ON [PRIMARY] mean?

Question

I\'m creating an SQL setup script and I\'m using someone else\'s script as an example. Here\'s an example of the script:

SET ANSI_NULLS ON
GO
SET QUOTED_IDE         


        

Answer 1

ON [PRIMARY] will create the structures on the "Primary" filegroup. In this case the primary key index and the table will be placed on the "Primary" filegroup within the database.
