Put question #, too.
Note:
Except for Question #18, when you join tables, you may use old-style join which is covered in
Chapter 7.
You can use any database software (MySQL, Oracle, SQL Server, etc.) to do this homework. I do
not recommend any single-user DBMS (e.g., MS Access) because they are NOT 100% compliant
to SQL standards.
Answer the following questions.
Use the operator and/or statement asked. Otherwise, you will have zero (0) point for the
question.
1. List the employee SSN, first and last name, birth date, and salary of each employee.

4. Employees get a 10% increase in their salary. List employee SSN, first and last name, the old salary,
and the new salary of each employee.

each employee first and last name, salary, gender, and department number.
