Is there any way in WebFOCUS to operate on timestamps? For example, I would like to take 08:30:30 + 00:15:15, or 08:30:30 - 00:15:15, and other calculations. Currently, I pull data in from our database in decimal format. So 08:30:00 becomes 8.500, and 08:45:00 becomes 8.750, and 08:45:15 becomes 8.754. Then I can perform the calculations I need to, and use a messy EDIT to convert back to timestamps for display purposes. COMPUTE SCHEDULEDTIMESTAMP/A8 = EDIT ( INT ( SCHEDULEDHOURS ) , '$$$$$$99' ) || ':' || EDIT ( INT ( ( SCHEDULEDHOURS - INT ( SCHEDULEDHOURS ) ) * 60 ) , '$$$$$$99' ) || ':' || EDIT ( ( ( ( SCHEDULEDHOURS - INT ( SCHEDULEDHOURS ) ) * 60 ) - INT ( ( SCHEDULEDHOURS - INT ( SCHEDULEDHOURS ) ) * 60 ) ) * 60 , '$$$$$$99' ); AS 'Scheduled,Hours' Any help on making this cleaner is appreciated. We are using WebFOCUS 7.1.3 in a Managed Reporting environment. | ||

Tom, I know what you mean, but you could always remove the "messy" code into a FUNCTION and then call it when needed - DEFINE FUNCTION DECTOTIM(DEC_TIME/D12.5)
HOURS/A2 = EDIT(INT(DEC_TIME),'$$$$$$99');
MINS/A2 = EDIT(INT((DEC_TIME - INT(DEC_TIME))*60),'$$$$$$99');
SECS/A2 = EDIT((((DEC_TIME - INT(DEC_TIME)) * 60) -
INT((DEC_TIME - INT(DEC_TIME)) * 60)) * 60,'$$$$$$99');
DECTOTIM/A8 = HOURS | ':' | MINS | ':' | SECS;
END
TABLE FILE CAR
SUM COMPUTE SCHEDHOURS/D12.5 = 8.754;
COMPUTE TIMEOUT/A8 = DECTOTIM(SCHEDHOURS); AS 'Scheduled,Hours'
BY COUNTRY
END
-RUNJust note that the output from the function is named the same as the function itself (DECTOTIM in this instance). T

I think the cleanest way is to convert the time you want to add/subtract to seconds and then use the HADD function: HADD(value, 'component', increment, length, outfield) Example -SET &CURR_DTTM = &YYMD || EDIT(HHMMSS('A8'),'99$99$99');
DEFINE FILE CAR
CURR_DTTM/HYYMDS WITH CAR = HINPUT(14, '&CURR_DTTM', 8, 'HYYMDS');
SEC_INCR/P4 WITH CAR = (15 * 60) + 15;
END
TABLE FILE CAR
PRINT CURR_DTTM SEC_INCR
COMPUTE NEXT_DTTM/HYYMDS = HADD(CURR_DTTM , 'SECONDS', SEC_INCR, 8, 'HYYMDS');
WHERE RECORDLIMIT EQ 1

I think that's the point Francis, one either uses decimal notation to ease the calculations or uses the WF built in functions to perfrom the calculations. Down to a comfort factor I think. I am sure that we would be inclined to use the internal functions, but for someone new to WF this may be a step too far? T

Tony A, thanks for the post on how to do custom functions, that has proven to be extremely useful. Francis, I understand your concept, but I would have to have some of the values in TIME format, and then some in just seconds to perform the calculations like that. Also, I am usually adding up multiple values and doing division, so that solution would not be elegant. | |||
