Barand Posted April 9, 2013 Share Posted April 9, 2013 IDs are unique identifiers for rows within a table and their sequence should be of no relevance to your application. The application should work the same way even if these unique ids were generated randomly rather sequentially. Sometimes I wish they were so people wouldn't have hangups about gaps in id sequences.
