TIME_RANGE

Determines the time range for the streaming events to be joined.

The

TIME_RANGE

function is applicable only for a Joiner transformation in a streaming mapping.

Syntax

TIME_RANGE(EventTime1,EventTime2,Format,Interval)

The following table describes the argument for this command:

Argument	Required/Optional	Description
EventTime1	Required	Date datatype. The time that a streaming event is generated in the master port of a Joiner transformation.
EventTime2	Required	Date datatype. The time that a streaming event is generated in the detail port of a Joiner transformation.
Format	Required	A format string that specifies the portion of the event time value you want to change. Enclose the format string within single quotation marks. For example, 'Seconds'. The format string is not case-sensitive. The format argument accepts the following values: Years Months Weeks Days Hours Minutes Seconds Milliseconds Microseconds
Interval	Required	An integer value which you want to change the event time value based on the format.

Return Value

NULL if you pass a null value to the function.

Example

The following example returns the time range expression for the Joiner transformation:

TIME_RANGE(EventTime1,EventTime2,'Second',4)

RETURN VALUE:

(EventTime1.<=(EventTime2).&&(EventTime2.<=(EventTime1.+(expr("INTERVAL 4 SECONDS")))))
