" * Using the final table list you created previously, select the Primary Keys for each table in your list for both Access and MySQL.
* Then, select one of the tables and complete field specifications for each field.
* Download and use the field specifications sheet.
Note: Your field specifications sheet does not have to have the same format as the one in your text. Just be sure to provide the same information.
Then write two queries
1. List each customer with all their orders.
2. List each product with its price, how much has been ordered and what is the sales total for that item. You will need to populate you tables with sample data."

"Hello,
I am very stressed about this assignment! I have been trying to figure this thing out for a week! I am sending the field specification list and the previous assignment for viewing. I can't figure the primary keys for Access. You may have to make up some info. Passing this grade will allow me to graduate. I have never asked for help so please work with me! I need this assignment as soon as possible. I actually have started I will attach also. Thanks in advance. Sir.
This is the first part.I couldn't figure out Access.
