8. For every manager (i. e., group on EMP_MGR), display the manager employee code (EMP_MGR) along with the total number (i. e., use COUNT() here) of employees s/he manages (requires a WHERE clause checking all EMP_MGRs that are not null). [hint: you should have 3 rows of output]. 9. Display the product description, the full customer name and the customer balance for products ordered by customers having a customer balance between $200.00 and $400 (inclusive). Order by customer first name, then last name, then initial. Look at the table layouts above and determine which tables to include here. You will need to use all tables and join those appropriately in the WHERE clause using PK/FK pairs (3 joins). The BETWEEN keyword should be used in the WHERE clause for the proper balances [hint: you should have 4 rows of output ordered properly]. 10. For every invoice, display the invoice number, invoice date and the total dollar amount for all products purchased in the invoice, ordered by invoice number in descending order and then by invoice date in ascending order. Here you will use an aggregate SUM(x,y) function in your SELECT clause to calculate the total dollar amount (a calculated field-name it with the alias TOTAL). Don't forget to join on the tables as well. [hint: you should have 8 rows of output ordered properly]. 11. Write SQL queries that use a set operation to display the UNION of the first and last names in table CUSTOMER and the first and last names in table EMPLOYEE. Include duplicates in the output [hint: you should have 27 rows of output]. 12. Create a SQL query that uses an uncorrelated subquery and no joins to display the descriptions for products provided by a vendor in area code 904. Remember, the main difference between a correlated subquery and uncorrelated subquery is that, in a correlated subquery, the inner query is dependent upon the outer query, while, with an uncorrelated query, the inner query does not depend upon the outer query. Instead, it runs just once. You should NOT use union, minus, or intersect in this query. The outer query will use the PRODUCT table and the inner query will use the VENDOR table [hint: you should have 3 records of output].
