MySQL NOT BETWEEN AND Operator

MySQL NOT BETWEEN AND Operator

The MySQL NOT BETWEEN ... AND ... operator is used to filter records that are not within a specified range. This operator is essential for querying data that falls outside of a particular range in SQL queries.

Syntax

SELECT column1, column2, ...
FROM table_name
WHERE column1 NOT BETWEEN value1 AND value2;

The NOT BETWEEN ... AND ... operator has the following components:

  • column1, column2, ...: The columns to be retrieved.
  • table_name: The name of the table from which to retrieve the data.
  • column1 NOT BETWEEN value1 AND value2: The condition to filter the records, where column1 is not within the range of value1 and value2.

Example MySQL NOT BETWEEN AND Operator

Let's look at some examples of the MySQL NOT BETWEEN ... AND ... operator:

Step 1: Using the Database

USE mydatabase;

This query sets the context to the database named mydatabase.

MySQL USE DATABASE

Step 2: Creating a Table

Create a table to work with:

CREATE TABLE employees (
    id INT AUTO_INCREMENT PRIMARY KEY,
    first_name VARCHAR(50) NOT NULL,
    last_name VARCHAR(50) NOT NULL,
    department VARCHAR(50),
    salary DECIMAL(10, 2)
);

This query creates a table named employees with columns for id, first_name, last_name, department, and salary.

MySQL CREATE TABLE

Step 3: Inserting Initial Rows

Insert some initial rows into the table:

INSERT INTO employees (first_name, last_name, department, salary)
VALUES ('John', 'Doe', 'HR', 50000.00),
       ('Jane', 'Smith', 'IT', 60000.00),
       ('Jim', 'Brown', 'IT', 55000.00),
       ('Jake', 'White', 'HR', 52000.00),
       ('Jill', 'Green', 'Marketing', 45000.00);

This query inserts five rows into the employees table.

MySQL INSERT INTO TABLE

Step 4: Using NOT BETWEEN AND with WHERE Clause

Use the NOT BETWEEN ... AND ... operator to filter records that fall outside a range:

SELECT * 
FROM employees 
WHERE salary NOT BETWEEN 50000 AND 60000;

This query retrieves all columns from the employees table where the salary is not between 50000 and 60000.

MySQL NOT BETWEEN AND WITH WHERE CLAUSE

Step 5: Using NOT BETWEEN AND with Multiple Conditions

Use the NOT BETWEEN ... AND ... operator with multiple conditions:

SELECT * 
FROM employees 
WHERE department = 'IT' AND salary NOT BETWEEN 50000 AND 60000;

This query retrieves all columns from the employees table where the department is 'IT' and the salary is not between 50000 and 60000.

MySQL NOT BETWEEN AND WITH MULTIPLE CONDITIONS

Conclusion

The MySQL NOT BETWEEN ... AND ... operator is a powerful tool for filtering records that fall outside a specified range. Understanding how to use the NOT BETWEEN ... AND ... operator is essential for effective data querying and analysis in MySQL.
