Introduction

Write a MySQL query to display the firstname of all students who have both “a” and “i” in their first name. I have used phpMyAdmin for the following example.

– students

StudentId FirstName LastName Admission_fee Admission_date Branch Branch_ID
1 John Smith 1000 2018-06-10 Computer Engineering 111
2 David Jones 1200 2018-06-20 Civil Engineering 222
3 Michael Johnson 900 2018-08-15 Chemical Engineering 333
4 Chris Lee 1500 2018-07-10 Electrical Engineering 444
5 Mike Brown 1600 2018-09-10 Mechanical Engineering 555
6 Lisa Smith 1800 2018-07-10 Computer Engineering 666
7 Mary Smith 1600 2018-06-11 Computer Engineering 777 
SELECT firstname
FROM students
WHERE firstname LIKE  '%a%'
AND firstname LIKE  '%i%'

Result
