ScriptEigener Objekttyp in der Automation Engine Function: Determines the difference between two date entries in days.

Syntax

DIFF_DATE(Date1, Date2)

Syntax	Description/Format
Date1 and Date2

Return code
Number of days lying between the two indicated dates

Comments

This script function determines the distance between Date1 and Date2 in days. It is possible for Date2 to be before or after Date1.

When defining dates, Date Format is optional. If no particular Date Format has been defined, the date must be entered in the format "YYMMDD" or "YYYYMMDD". You can use a colon or semicolon as a separator between Date Format and date.

Example

The first example calculates the difference between date entries. The dates use the default format "YYMMDD" and "YYYYMMDD". The result "1" is output in the report.

:SET &DIFF# = DIFF_DATE("000330","20000331")
:PRINT &DIFF#

In the second example, the date entries are assigned to the script variables. The script function is called with this script variable. Because the data do not use a default format, the special date format must also be used with the script variables. The result "366" is output in the report.

:SET &DATE1# = "01-01-2000"
:SET &DATE2# = "01012001"
:SET &DIFF# = DIFF_DATE("DD-MM-YYYY:&DATE1#", "DDMMYYYY;&DATE2#")
:PRINT &DIFF#

The third example has the same result as the second example. The difference here is that the script variables are assigned a date format and a date.

:SET &DATE1# = "DD-MM-YYYY:01-01-2000"
:SET &DATE2# = "DDMMYYYY:01012001"
:SET &DIFF# = DIFF_DATE(&DATE1#, &DATE2#)
:PRINT &DIFF#
