Need help with the SQL queries to answer these questions:

Part 1: Set up the environment which needed to run your queries. This environment includes the employee schema and importing data to the schema. For this homework we are using an Employee sample database which you can find using below URL: https://dev.mysql.com/doc/employee/en/ Part 3 which is installation holds the path to GitHub which you can download all the required files. Please download an employee sample database from GitHub by using this URL: https://github.com/datacharmer/test_db After extracting the folder "test_db-master" open MySQL WorkBench and then File --> Open SQL Script and chose Employees.sql and run it. In the last part of the Employees.sql file where is has select and source it tries to upload the .dump file right after it creates the schema. If that part gives you an error first run from the beginning of the code up to line number 97 right before create view. After schema has been created you can go to Data Import/Restore and import all of dump file in test_db-master folder. After you created the schema and loaded with data you can start running the queries. 19) Who was the first person which has been employed with the company? 20) How many different job title do we have in this schema? 21) How many male employees do we have in the company? 22) What is the ratio of female employees' vs male employees in the company? 23) What is the ratio of salary of female / male in the company?
