RAND

Returns a random number between 0 and 1. This is useful for probability scenarios.

Syntax

RAND( seed )

The following table describes the argument for this command:

Argument	Required/ Optional	Description
seed	Optional	Numeric. Starting value for the Integration Service to generate the random number. Value must be a constant. If you do not enter a seed, the Data Integration Service uses the current system time to derive the numbers of seconds since January 1, 1971. It uses this value as the seed.

Return Value

Numeric.

For the same seed, the

Data Integration Service

generates the same sequence of numbers.

Example

The following expression may return a value of 0.417022004702574:
