This function updates an employee's manager by first querying the employee and manager lists, prompting the user to select which employee's manager to update and their new manager, and then creating a temporary table to hold the employee IDs and full names before updating the employee's manager ID with the selected manager's ID. Once the update is complete, the temporary table is dropped and the user is returned to the main menu.

}This function prompts the user to select a department and then queries the database to calculate and display the total utilized budget of that department, which is calculated as the sum of all salaries of employees who belong to that department.

// Query departments to get a list of available departments
connection.query(`SELECT name FROM department`, function (err, res) {
