Insert, Update, Delete Sandbox fun

After reading through merging, inserting, updating, and deleting I performed the exercises in the book, but it didn't stick in my head as well I thought it would.  For that reason I began to play on my own using the database that I had created in the past from the contacts in my phone.  Using the phone number as the primary key I had two tables (the old table, and a new table) and I began to update, and insert new contacts on the old table.

Sandbox practice is a great way to learn, and can be more relative in the real world as well.  I will post the DDL from my update statements when I get back to my home cpu...

Cheers!
