Thanks alot.How about polymorphism in sql? Could we use stored procedures for polymorphism?
And for nested relationships can we define an attribute as OId and use it in a select query to point to the table that we want use it in our nested relationship?
HUH???? How can a stored procedure be used to implement polymorphism? sql is NOT an OO programming language. It is a data storage system. It is not ever going to be this type of OO entity that you are talking about.
