SQL Exercises: Using where clause with not and between operators

SQL Wildcard & Special Operator: Exercise-8 with Solution

From the following table, write a SQL query to find the details of all salespeople except those whose names begin with any letter between 'A' and 'M' . Return salesman_id, name, city, commission.

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 all columns from the 'salesman' table.
SELECT *
-- Specifies the table from which to retrieve the data (in this case, 'salesman').
FROM salesman
-- Filters the rows to only include those where the 'name' column is not between 'A' and 'L'.
WHERE name NOT BETWEEN 'A' AND 'L';

Output of the Query:

salesman_id	name		city		commission
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
