📚 MIN OPERATOR

The MIN function is used in SQL to return the lowest value in a specified column.
It is useful for finding the smallest number, earliest date, or alphabetically first string.

---

🛠️ Basic Syntax

SELECT MIN(column_name)
FROM table_name
WHERE condition;

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

Example

SELECT MIN(salary)
FROM employees;

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

Key Points

• Works with numeric, date, and text columns (for text, it returns the alphabetically first value).
• Ignores NULL values.
• Can be used inside a subquery or with GROUP BY.

Additional Example

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

• This query shows the lowest salary for each department.
