MIN Function

The MIN function returns the minimum value in a set of rows. DISTINCT or ALL may be used but do not affect the result.

Syntax

Copy
MIN ( [ DISTINCT | ALL ] expression )

Arguments

expression

The target column or expression that the function operates on.

DISTINCT | ALL

With the argument DISTINCT, the function eliminates all duplicate values from the specified expression before calculating the minimum. With the argument ALL, the function retains all duplicate values from the expression for calculating the minimum. ALL is the default.

Data Types

Accepts any data type except Boolean as input. Returns the same data type as expression. The Boolean equivalent of the MIN function is BOOL_AND Function, and the Boolean equivalent of MAX is BOOL_OR Function.
