MIN() Function

The MIN() function is used to retrieve the smallest value from a specified column in a dataset. This function is particularly useful for identifying the lowest scores, minimum sales, or least significant performance indicators. The syntax is simple: SELECT MIN(column_name) FROM table_name WHERE condition;. For example, to find the lowest salary among employees, you would use: SELECT MIN(salary) FROM employees;. This function only considers non-NULL values, ensuring that the returned minimum is meaningful. Understanding minimum values is crucial for risk assessment and management, allowing organizations to identify underperformers or potential areas for improvement. The MIN() function can also be combined with GROUP BY to assess minimum values across different categories, such as the lowest salary in each department.
