Screen shots of SQL queries you used to retrieve data from the tables along with the query results. For each query, explain in a complete, coherent sentence what it is intended to do, what data is expected as a result and how they are different from previous queries. Clearly identify each screen shot you paste into this section. To create queries, use the following structures: 4. A query that is based on two tables and includes both an arithmetic and a special operator in the conditional expression. a. b. A query that is based on more than two tables and includes both an arithmetic and a special operator in the conditional expression. Both the arithmetic and the special operator must be different from the ones used in part a c. A query that includes a sub-query.
