A couple of questions on tables....

If you execute a SQL statement (SQL2000) and bring down all the attributes in
a table, then the constraints come down as well? What if yoy select some
attributes but not all, but all the fields necessary for creating the
constraints, are the constraints extracted?

If you execute an SQL statment which brings in data from several tables, you
have to create your own constraints?

If you run a SQL statement and no rows are returned, is the datatable created
with all of the columns or do you have use the method to fill the schema?
