Use the database and tables from last week's assignment to write SQL queries using Between, Like, and Union:
1. Write a SQL query that joins two tables in the example database and uses BETWEEN to restrict record selection. Use salary to
restrict data.
2. Write a SQL query that joins two tables in the example database and uses BETWEEN to restrict record selection. Use hire
dates to restrict data.
3. Write a SQL query that joins two tables in the example database and uses LIKE to restrict record selection. Use telephone
area codes to restrict data.
4. Write a SQL query that joins two tables in the example database and uses LIKE to restrict record selection. Use age to

2. Increase all employees' salaries by 5%.
3. Choose an employee from the Employee table and delete that employee.
Use the database and tables from last week's assignment to write SQL statements that do the following:
1. Calculate the average salary for all employees.
2. Calculate the maximum salaries for exempt and non-exempt employees.
