View the table

SQLite Code :

-- Selecting the "first_name" column and renaming it as "First Name"
-- Selecting the "last_name" column and renaming it as "Last Name"
SELECT first_name "First Name", last_name "Last Name"
-- Specifying the table from which to retrieve the data, in this case, "employees"
FROM employees;

Output:

First Name  Last Name
----------  ----------
Steven      King
Neena       Kochhar
Lex         De Haan
Alexander   Hunold
Bruce       Ernst

Explanation:

The above SQLite query retrieves data from a table named "employees." It selects the "first_name" column from the table and renames it as "First Name." Similarly, it selects the "last_name" column and renames it as "Last Name." The result is a list of employee first names and last names from the "employees" table.
