I couldn't get differences in timestamps in a straightforward manner in V2R4.0. May have been my fault, but I tried everyway from
Sunday. This is an example of my kludge (it works):
SELECT CAST(CAST(CAST(LOGDATE AS FORMAT 'YYYY-MM-DD') AS CHAR(10)) || '
'
|| CAST( LOGTIME AS CHAR(15)) AS TIMESTAMP)
,CAST(CAST(CAST(LOGONDATE AS FORMAT 'YYYY-MM-DD') AS CHAR(10)) || ' '
||
CAST(LOGONTIME AS CHAR(15)) AS TIMESTAMP)
,CAST((LOGDATE - LOGONDATE) * 24 * 3600
+ (EXTRACT(HOUR FROM LOGTIME) - EXTRACT(HOUR FROM LOGONTIME)) * 3600
+ (EXTRACT(MINUTE FROM LOGTIME) - EXTRACT(MINUTE FROM LOGONTIME)) * 60
+ (EXTRACT(SECOND FROM LOGTIME) - EXTRACT(SECOND FROM LOGONTIME))
AS INTEGER)
LOGTIME and LOGONTIME come from DBC.LOGONOFF.
