Fermat's principle and a non-physical conclusion. WebIBM Greater Kolkata Area1 month agoBe among the first 25 applicantsSee who IBM has hired for this roleNo longer accepting applications. If you have a class that records timestamps when the data is added, then that data will be in sequence with your IDKEY values - that is, TimeStamp1 < TimeStamp2 if and only if ID1 < ID2 for all IDs and TimeStamp values in table - then you can use this knowledge to increase performance for queries against TimeStamp ranges. This version is fixed, but you can, however, go through the upgrade process to achieve a higher version. Note that setting ERROR_ON_OVERLAP_TIME to FALSE can potentially cause some time sequences to be reversed. This is due to different DST rules in effect for the time zone regions affected between the different time zone file versions across the different database servers.
