Write a SQL statement that displays all the information about all salespeople.

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:

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;

Output of the Query:

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.
Alternate command:
SELECT salesman_id, name, city, commission
