I had this select statement run right at the midnight break... SELECT.STATEMENT = 'SELECT TSE USING D.TSE WITH ACT.BATCH.STATUS = "EXTCOMP" AND WITH COMPLETED # "COMP" OR WITH CALL.IN.DATE LE "':OCONV(DATE(),'D4/'):'" AND WITH CALL.IN.TIME LE "':OCONV(TIME(),'MTH'):'"' AND WITH COMPLETED # "COMP"'
I know the first "OR" clause failed... So it appears that The CallInDate received the POST MIDNIGHT DATE -- in this case 04/06/2006 While the CallInTime received the PRE MIDNIGHT TIME - something like 23:59:59 While I did not store the actual command, it's the only structure of this command that would return the data set processed - and I know that a time stamp on the run data was at 00:00:12, so this select DID happen right a the midnight break. Has anyone ever seen a case like this? Either the select statement did not fill in "Left to Right" (is that possible? The worst case I had already planned for: a processing loop would get yesterday's date (04/05/2006), tomorrow's time (00:00:01), and that would ALWAYS return zero records - no harm no foul - we'll get the records in the next loop!) or **somehow** the DATE() and TIME() were not updated in order or they were not updated by the environment as I would have "expected". If TIME() goes to 00:00:00, I expect the DATE() is also 'right then' updated. It was a head scratcher why records for today were handled, and I traced it back to this select as being the only way it could happen. I know DATE() and TIME() are beasts -- but should I logically every expect that statements build 'left to right' -- and if that's not the case, can DATE() and TIME() become 'dis-synchronized'? Or should I have played the lottery yesterday since this was also a 1 in 16 billion odds? My option now is to put this whole process to sleep for 10 seconds at 5 seconds to midnight! Is that too crazy? I know others do time-aware processing - how do you ensure this kind of oddness does not occur? Or does it and you just do the sleep until you know for sure route?
