Consider the database table structure shown in the figure. (a) Write a SELECT statement (compatible with an Oracle RDBMS) that returns all the invoice numbers for invoices with a total greater than 1200 or that are due after June of 2010 and that have an amount due that is positive. (b) Then write two rows of sample data that might be retrieved by the query. What is actually retrieved depends on what is in the table. The data you write does not have to match any data that is actually in our sample tables.
