SQL MIN() function

MIN() function

The aggregate function SQL MIN() is used to find the minimum value or lowest value of a column or expression. This function is useful to determine the smallest of all selected values of a column.

MySQL, PostgreSQL, and SQL Server

All the above platforms support the SQL syntax of MIN.

DB2 and Oracle Syntax:

MIN ([ALL | DISTINCT] expression ) OVER (window_clause)
