MySQL Operators
Operators in MySQL are used to perform operations on values and produce a result. They include arithmetic operators, comparison operators, logical operators, and more.
Arithmetic Operators:
SELECT 10 + 5 AS addition,
10 - 5 AS subtraction,
10 * 5 AS multiplication,
10 / 5 AS division,
10 % 3 AS modulus;
This query demonstrates the arithmetic operators in MySQL, including addition, subtraction, multiplication, division, and modulus.
Comparison Operators:
SELECT * FROM employees
WHERE salary > 5000;
This query selects all employees with a salary greater than 5000, using the comparison operator >.
Logical Operators:
SELECT * FROM employees
WHERE department_id = 1 AND salary > 5000;
This query selects employees from department 1 with a salary greater than 5000, using the logical AND operator.
These are just a few examples of operators in MySQL. They are essential for building complex queries and performing various operations on data.
