I need help writing a few SQL queries/codes. I'll post them below!

1) Using ROWNUM to limit the size of the result. (Notice that SQL and some systems use the LIMIT or TOP clauses. Oracle uses ROENUM to accomplish similar tasks.) Find the ssn, lname, and salary of only four employees.

2) TOP-N query. Find the ssn, lname, and salary of the four highest paid employees.

3) TOP-N query. Find the ssn, lname, and salary of the four lowest paid employees

4) TOP-N query. Find the lowest two salaries in the company.(In this database, the two lowest salaries are 25K and 30K.)
