MAX (Dates)

Returns the latest date found within a port or group. You can apply a filter to limit the rows in the search. You can nest only one other aggregate function within MAX.

You can also use MAX to return the largest numeric value or the highest string value in a port or group.

Syntax

MAX( date [, filter_condition] )

The following table describes the arguments for this command:

Argument	Required/ Optional	Description
date	Required	Date/Time datatype. Passes the date for which you want to return a maximum date. You can enter any valid transformation expression.
filter_condition	Optional	Limits the rows in the search. The filter condition must be a numeric value or evaluate to TRUE, FALSE, or NULL. You can enter any valid transformation expression.

Return Value

Date.

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).

Example

You can return the maximum date for a port or group. The following expression returns the maximum order date for flashlights:

MAX( ORDERDATE, ITEM_NAME='Flashlight' )

ITEM_NAME	ORDER_DATE
Flashlight	Apr 20 1998
Regulator System	May 15 1998
Flashlight	Sep 21 1998
Diving Hood	Aug 18 1998
Flashlight	NULL
