Joe,
INDENTITY column does not guarantee a monotonically increasing sequence but it does guarantee a unique key to identify the row . If you want to
ensure the values shld be in increasing order , you need to get rid from IDENTITY column and make it as a INTEGER NOT NULL , and populate that
with either CSUM or RANK function , make sure while using the RANK, how unique the data is going to be
The huge gap is due to IDCOL batch size
Thanks,
Srini
