Answer 1

SELECT customer_last_name, customer_city, customer_zip FROM customers WHERE customer_state = 'IL' ORDER BY customer_last_name DESC;

Step-by-step explanation:

Here, we are given a SCHEMA with the table name customers.

It's creation command and commands to insert values are also given.

We have to print the customer last name, city and zip code of all the customers who have their state as IL in the decreasing order of their last names.

Let us learn a few concepts first.

1. To print only a specified number of columns:

We can write the column names to be printed after the SELECT command.

2. To print results as per a condition:

We can use WHERE clause for this purpose.

3. To print in descending order:

We can use ORDER BY clause with the option DESC to fulfill the purpose.

Therefore, the answer to our problem is:

SELECT customer_last_name, customer_city, customer_zip FROM customers WHERE customer_state = 'IL' ORDER BY customer_last_name DESC;

Output of the command is also attached as screenshot in the answer area.
