The Mertech Flex2SQL GUI migration tool and Mertech drivers use 01/01/0001 as the default NULL value for DataFlex DF_DATE and DF_DATETIME fields to be consistent with the DataFlex dummy zero date setting.
Note: The MSSQL drivers use 01/01/1753 as the default null value.
Note: The MySQL drivers (Windows versions 12.0.6020.0 and 12.1.6020.0 and SCO version 11.0.5702.1) were modified in March of 2012 to use 00/00/0000 as the default NULL value.
Crystal Reports versions 9.0 and above have a lower date bound of 01/01/0100.
