RANK

RANK

The RANK() function assigns a unique rank to each value within an ordered group of values.

The rank value starts at 1 and continues up sequentially. If two values are the same, they have the same rank.

Syntax

RANK() OVER (
[ PARTITION BY <expr1> ]
ORDER BY <expr2> [ { ASC | DESC } ]
[ <window_frame> ]
)

Examples

Create the table

CREATE TABLE employees (
employee_id INT,
first_name VARCHAR,
last_name VARCHAR,
department VARCHAR,
salary INT
);

Insert data

INSERT INTO employees (employee_id, first_name, last_name, department, salary) VALUES
(1, 'John', 'Doe', 'IT', 90000),
(2, 'Jane', 'Smith', 'HR', 85000),
(3, 'Mike', 'Johnson', 'IT', 82000),
(4, 'Sara', 'Williams', 'Sales', 77000),
(5, 'Tom', 'Brown', 'HR', 75000);
