AND - MySQL Conditions

In MySQL, the AND operator is used in a WHERE clause to combine multiple conditions. The AND operator returns true only if both conditions are met. In this tutorial, we'll discuss the syntax, examples, output, explanation, use, and important points of using the AND operator in MySQL conditions.

Syntax

The syntax for using the AND operator in MySQL conditions is as follows:

SELECT column1, column2, ...
FROM table_name
WHERE condition1 AND condition2 AND condition3 ...;

In the above syntax, "column1, column2, ..." refers to the names of the columns you want to retrieve, "table_name" refers to the name of the table you want to query, and "condition1, condition2, ..." refers to the conditions that must be met.

Example

Let's say we have a table called "users" with columns "id", "name", "email", and "age". Here's an example of using the AND operator to retrieve all users who are over 18 years old and have a Gmail address:

SELECT *
FROM users
WHERE age > 18 AND email LIKE '%@gmail.com';

Output

When we run the example code above, the output will be all the rows from the "users" table that fulfill both the conditions:

+------+-------+---------------------+-----+
| id   | name  | email               | age |
+------+-------+---------------------+-----+
|    1 | John  | john@gmail.com      |  20 |
|    3 | Sarah | sarah@gmail.com     |  25 |
+------+-------+---------------------+-----+

Explanation

In the example above, we used the AND operator in the WHERE clause to filter the results based on two conditions: age greater than 18 and email containing "@gmail.com". If conditions are true for particular row, that row will be included in the results.

Use

The AND operator is useful for filtering data based on multiple conditions in MySQL. It allows you to retrieve only the data that meets specific criteria.

Important Points

  • The AND operator returns true only if both conditions are met.
  • You can have any number of conditions in the WHERE clause, separated by AND operators.
  • The AND operator has a higher precedence than the OR operator, which means that conditions connected by AND are evaluated before those connected by OR.

Summary

In this tutorial, we discussed how to use the AND operator in MySQL conditions. We covered the syntax, example, output, explanation, use, and important points related to the AND operator. With this knowledge, you can now filter MySQL data based on multiple conditions using the AND operator.
