  From what you posted I don't see any need for any looping construct or dynamic sql.

  In order to help we will need a few things:

  1. Sample DDL in the form of CREATE TABLE statements

  2. Sample data in the form of INSERT INTO statements

  3. Expected results based on the sample data

  Please take a few minutes and read the first article in my signature for best practices when posting questions.
