MySQL BETWEEN AND Operator

MySQL BETWEEN AND Operator

The MySQL BETWEEN ... AND ... operator is used to filter records within a specified range. This operator is essential for querying data that falls between two values, inclusive.

---

Syntax

SELECT column1, column2, ...
FROM table_name
WHERE column1 BETWEEN value1 AND value2;

The 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 BETWEEN value1 AND value2: The condition to filter the records, where column1 is within the range of value1 and value2, inclusive.

Example MySQL BETWEEN AND Operator

Let's look at some examples of the MySQL BETWEEN ... AND ... operator:

Step 1: Using the Database

USE mydatabase;

This query sets the context to the database named mydatabase.

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.

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.

Step 4: Using BETWEEN AND with WHERE Clause

Use the BETWEEN ... AND ... operator to filter records based on a range:

SELECT * 
FROM employees 
WHERE salary BETWEEN 50000 AND 60000;

This query retrieves all columns from the employees table where the salary is between 50000 and 60000, inclusive.

Step 5: Using BETWEEN AND with Multiple Conditions

Use the BETWEEN ... AND ... operator with multiple conditions:

SELECT * 
FROM employees 
WHERE department = 'IT' AND salary BETWEEN 50000 AND 60000;

This query retrieves all columns from the employees table where the department is 'IT' and the salary is between 50000 and 60000, inclusive.

Conclusion

The MySQL BETWEEN ... AND ... operator is a powerful tool for filtering records within a specified range. Understanding how to use the BETWEEN ... AND ... operator is essential for effective data querying and analysis in MySQL.
