I have a databade model that I need to write sql queries for they are.

Fetch first name, last name and hire date of all employees who were hired after January $1,1999.$

List all the job ids and titles with a max salary of greater than $$15000$ and a min salary less than $$9000.$

Write a SQL query to retrieve all columns from the 'countries' table for countries whose names start with the letter $\text{'}$A$\text{'}.$ The results should be ordered in descending order based on the country$\_$id$.$

Retrieve the columns region name and country name from the regions and countries tables. Your query will need to reference both tables by linking them through matching values in related attributes. $($Use Join$)$

Find employees working in the $\text{'}$IT$\text{'}$ department $($Use Subquery$)$

Get the highest paid employee's details. $($Use Subquery$)$

Find employees along with their managers' names. $($Use Join$)$

Retrieve the list of countries and their respective regions, but only for countries in the 'Americas' region. $($Use Join$)$
