	I'm afraid that your question is much to general to be answered.
Frankly, I'm not sure what you mean by "nested SQL statement."  Further,
It sounds like you need some general knowledge.  SInce this is an
internship, ask them to buy you some books:

................Database Design for Mere Mortals
any/all of:.....PostgreSQL Introduction & Concepts
................SQL for Smarties

This is the wrong list for questions about ADO.  Try pgsql-interfaces
instead, or perhaps MSDN (msdn.microsoft.com).

Good luck!
