LEAST

Returns the smallest value from a list of input values. By default, the match is case sensitive.

Syntax

LEAST( value1, [value2, ..., valueN,] )

The following table describes the arguments for this command:

Argument	Required/ Optional	Description
value	Required	Any datatype except Binary. Datatype must be compatible with other values. Value you want to compare against other values. You must enter at least one value argument. If the value is Numeric, and other input values are of other numeric datatypes, all values use the highest precision possible. For example, if some values are of the Integer datatype and others are of the Double datatype, the PowerCenter Integration Service converts the values to Double.
CaseFlag	Optional	Must be an integer. Specify a value when the input value argument is a string value. Determines whether the arguments in this function are case sensitive. You can enter any valid transformation expression. When CaseFlag is a number other than 0, the function is case sensitive. When CaseFlag is 0, the function is not case sensitive. Default is case sensitive.

Return Value

value1
if it is the smallest of the input values, value2
if it is the smallest of the input values, and so on.

NULL if any of the arguments is null.

Example

The following expression returns the smallest quantity of items ordered:

LEAST( QUANTITY1, QUANTITY2, QUANTITY3 )

QUANTITIY1	QUANTITY2	QUANTITY3	RETURN VALUE
150	756	27	27
			NULL
5000	97	17	17
120	1724	965	120
