Hi,
As I understand it the only reason to use 64bit integers for IDs would
be for tables with more than 2 billion records (in the positive range).
There is a related question on StackOverflow about this
http://stackoverflow.com/questions/2124631/sql-server-int-or-bigint-database-table-ids
Are there really feature classes with this many records in existence?
Regards,
Seth,
In many cases with an RDBMS the FID is the primary key and there are
a variety of reasons these might not be sequential starting from zero.
The issue initially came up in Barcelona with someone from OSM who I
believe was concerned about when the OSM object ids were going to be
larger than two billion.
Best regards,
