Using MySQL, create a table named INV_MYSQL with the same fields as in Problem 17, except, use the AUTO_INCREMENT feature for the INV_NUM field.

MySql Workbench CREATE TABLE students (  id INT PRIMARY KEY,  first_name VARCHAR(50),  last_name VARCHAR(50),  age INT,  major VARCHAR(50),  faculty VARCHAR(50)); CREATE TABLE location (  id INT PRIMARY KEY,  name VARCHAR(50),  rooms INT); CREATE TABLE faculty (  id INT PRIMARY KEY,  name VARCHAR(50),  department_id INT); 1. List last name of all students whose first name is longer than 4 letters in ascending order accordingto the last name. Duplicated rows should be removed from the output.2. Count the total number of rooms in Location.3. Find the number of students in each major.4. Find the number of employees in each department who get no commission or have salary less than5000.5. Find the maximum salary of employees in each department that the employee was hired 15 yearsbefore now. *hint: user TIMESTAMPDIFF(<unit type>,<Date_value 1>,<Date_value 2>), the unitcan be YEAR, MONTH, DAY, HOUR, etc...

Which group function can be used to perform a count that includes NULL values?

Write a procedure named prc_cust_add to add a new customer to the CUST_MYSQL table. Use the following values in the new record: CUIST_NUM CUST_LNAME CUST_FNAME CUST_BALANCE 2003 Rauthor Peter 0.00 (You should execute the procedure and verify that the new customer was added to ensure your code is correct.)
