MIN (Numbers)

Returns the smallest numeric value found in 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 MIN, and the nested function must return a numeric datatype.

You can also use MIN to return the latest date or the lowest string value in a port or group.

Syntax

MIN( numeric_value [, filter_condition] )

The following table describes the arguments for this command:

Argument	Required/ Optional	Description
numeric_value	Required	Numeric datatypes. Passes the values for which you want to return minimum value. 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

Numeric value.

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).

If the return value is Decimal with precision greater than 15, you can enable high precision to ensure decimal precision up to 38 digits.

Nulls

If a single value is NULL, MIN ignores it. However, if all values passed from the port are NULL, MIN returns NULL.

By default, the

PowerCenter Integration Service

treats null values as NULLs in aggregate functions. If you pass an entire port or group of null values, the function returns NULL. However, when you configure the

PowerCenter Integration Service

, you can choose how you want to handle null values in aggregate functions. You can treat null values as 0 in aggregate functions or as NULL.

Group By

MIN groups values based on group by ports you define in the transformation, returning one result for each group.

If there is no group by port, MIN treats all rows as one group, returning one value.

Example

The following expression returns the minimum price for flashlights:

MIN ( PRICE, ITEM_NAME='Flashlight' )

ITEM_NAME	PRICE
Flashlight	10.00
Regulator System	360.00
Flashlight	55.00
Diving Hood	79.00
Halogen Flashlight	162.00
Flashlight	85.00
Flashlight	NULL
RETURN VALUE: 10.00
