How to Create Table with 'Required' set

Hi all,

I want to know how to create table by using "Required" set.

I've created the coding required to create a new table, but I also need to set the 'Required' parameter to 'Yes' on some selected fields.

Is is possible to do this whilst creating the table with the 'CREATE TABLE...' statement or is there another way of programatically setting the 'Required' parameter?

Thanks in Advance.
