is there any implementation of nested tables in SQL ?

i have been told by my teacher that i will have to use nested tables in my project and i am using sql server 2008. i have searched the internet but have failed to find any useful info.. i read in a post in a forum that that concept of nested tables does not exist the way it does in oracle ( that is table within a table) but has the concept of primary and foreign key instead ..

PLEASE TELL ME WHETHER NEST TABLES EXIST IN SQL ?
AND IF SO PLEASE HELP ME WITH THE CONCEPT ...
THANKYOU !

By SQL you mean SQL Server correct?
SQL is a declarative language used with relational databases.
SQL Server is a relational database product.

If it is SQL Server, I will move this to the SQL Server forum.
Or another mod will.

pootle flump ur codings are working excelent.

Standard SQL has nested table types (AKA structured types). SQL Server 2008 does not.

As an aside, it pains me that colleges are teaching topics like nested tables, a feature added to DBMSs like Oracle purely to tick a box in their "object-relational" feature list and of no practical use to anybody. So every year a mass of students emerge from their colleges thinking nested tables are something you should be using in your databases, and if unchecked no doubt introduce them into their employers' databases. *Sigh*.
