Re: After partition also select is scanning all the partitions - need help

All the rows in the partition have the same date (Date='2010-09-10') and you have not given any further restrictions, so the SELECT will scan (and deliver) all the rows in that partition.

partitions: PART_20100910000000
Says that it will scan only the one partition

This cannot be trusted as much:
rows: 5379
