min

Selects an item from the input sequence argument whose value is less than or equal to the value of every other item in the input sequence. If there are two or more such items, then the specific item whose value is returned is implementation dependent.

Syntax

fn:min(arg, collation)

The following table describes the argument for this command:

Argument	Required/Optional	Description
arg	Required	The sequence of values.
collation	Required	The collation to use for comparing strings.

Return Value

xs:anyAtomicType?

NULL if all values passed to the function are NULL, or if no rows are selected (for example, the filter condition evaluates to FALSE or NULL for all rows).
