Sample Solution:

SQL Code:

-- 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;

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

Code Explanation:

The said query in SQL that selects all columns from the table 'salesman'. It returns all the rows and columns of the table salesman.

SQL syntax:

SELECT [DISTINCT] [<qualifier>.]<column_name> |*|
<expression>
[AS <column_alias>],...
FROM <table_or_view_name> |
<inline_view>
[[AS] <table_alias>]
[WHERE <predicate>]
[GROUP BY [<qualifier>.]<column_name>,...
[HAVING <predicate>]
]
[ORDER_BY <column_name> |
<column_number>
[ASC | DESC],...
];

Note: Use * to get a complete list of the columns from a table.

SELECT salesman_id, name, city, commission
