Introduction

Write a MySQL query to display the names (firstname, lastname) using alias name “First Name”, “Last Name”. I have used phpMyAdmin for the following example.

– students

StudentId FirstName LastName Admission_fee Admission_date Branch
1 John Smith 1000 2018-06-10 Computer Engineering
2 David Jones 1200 2018-06-20 Civil Engineering
3 Michael Johnson 900 2018-08-15 Chemical Engineering
4 Chris Lee 1500 2018-07-10 Electrical Engineering
5 Mike Brown 1600 2018-09-10 Mechanical Engineering
6 Lisa Smith 1800 2018-07-10 Computer Engineering
7 Mary Smith 1600 2018-06-11 Computer Engineering 
SELECT firstname "First Name", lastname "Last Name"
FROM students

Result

Write a MySQL query to display the names (firstname, lastname) using alias name "First Name", "Last Name"
