Solution

This SQL query is designed to select all records from the 'customers' table where the 'country' is 'USA' and the 'state' is 'NV'. Here's a step-by-step breakdown:

SELECT *: This is the command to select data. The asterisk (*) is a wildcard character that means "all". So, SELECT * means select all columns.
FROM customers: This specifies the table from which to select the data. In this case, the data is being selected from a table named 'customers'.
WHERE: This keyword is used to filter the records. It is followed by a condition that the records must meet.
country = 'USA' AND state = 'NV': This is the condition that the records must meet. The query will only select records where the 'country' column is 'USA' and the 'state' column is 'NV'. The AND keyword is used to combine conditions, and it only selects records where both conditions are true.

So, in summary, this query will return all records from the 'customers' table where the customer is located in the state of Nevada, USA.
