📚 MAX OPERATOR

The MAX function is used in SQL to return the highest value in a specified column.
It is often used to find the largest number, latest date, or alphabetically last string.

---

🛠️ Basic Syntax

SELECT MAX(column_name)
FROM table_name
WHERE condition;

• MAX(column_name) returns the maximum value from the specified column.
• Can be combined with GROUP BY to find maximum values within groups.

Example

SELECT MAX(salary)
FROM employees;

• This query returns the highest salary from the employees table.

Key Points

• Works with numeric, date, and text columns (for text, it returns the alphabetically last value).
• Ignores NULL values.
• Can be used inside a subquery to filter records.

Additional Example

SELECT department, MAX(salary)
FROM employees
GROUP BY department;

• This query shows the highest salary for each department.
