SQL Basic Select Statement: Exercise-9 with Solution.

From the following table, write a SQL query to locate salespeople who live in the city of 'Paris'. Return salesperson's name, city. 

Sample table: salesman

 salesman_id |    name    |   city   | commission 
-------------+------------+----------+------------
        5001 | James Hoog | New York |       0.15
        5002 | Nail Knite | Paris    |       0.13
        5005 | Pit Alex   | London   |       0.11
        5006 | Mc Lyon    | Paris    |       0.14
        5007 | Paul Adam  | Rome     |       0.13
        5003 | Lauson Hen | San Jose |       0.12

Sample Solution :

-- This query selects specific columns 'name' and 'city' from the 'salesman' table.
SELECT name, city
-- Specifies the table from which to retrieve the data (in this case, 'salesman').
FROM salesman
-- Filters the rows to only include those where the 'city' column has the value 'Paris'.
WHERE city = 'Paris';

Output of the Query:

name		city
Nail Knite	Paris
Mc Lyon		Paris

Code Explanation:

The said query in SQL that selects "name" and "city" columns from the 'salesman' table where the value of "city" column is 'Paris'. The WHERE clause is used to filter the rows and only return the rows that match the condition specified in the WHERE clause.
As a result, all the rows from the 'salesman' table with a "city" column of 'Paris' will be returned, along with their "name" and "city" columns.
