MySQL's AND operator can be used in conjunction with a WHERE clause to return values that satisfy all the conditions separated by AND in the WHERE clause.

Syntax

SELECT column_name(s)
FROM table_name
WHERE condition1 AND condition2;

Examples

Consider the following table about some students:

student_id

fname

lname

day_enrolled

age

username

1

Sky

Towner

2015-12-03

17

2

The above sample table can be created using the code here.

Basic usage

To return students who are older than 17 and enrolled after 2017-01-01:

SELECT *
FROM studentsWHERE age > 17 AND day_enrolled > '2017-01-01';
+------------+--------+-------+--------------+------+----------+
| student_id | fname | lname | day_enrolled | age | username |
+------------+--------+-------+--------------+------+----------+
| 3 | Travis | Apple | 2018-08-14 | 18 | tapple3 |
+------------+--------+-------+--------------+------+----------+

We can see that Travis is the only student to meet both conditions.

NOTE

There is no limit to how many conditions we can apply (i.e. we can use many AND).
