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

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.
