Home -> Community -> Mailing Lists -> Oracle-L -> RE: find out the rollback
!! Please do not post Off Topic to this List !!
200,000 @ 50 bytes, I would say just over 40Mb of rollback.
Not sure how you came up with 21akh to 200,000 :)

200,0000 (two hundred thousand:)
English is indeed an great language as it changes in its nuances as geographic locations change ..its friday finally!
srinivas for estimating rollback, consider taking snapshots of v$rollstat.waits (specified in bytes) before and after a sample delete on your table and extrapolate to identify the amount of rollback you would require for successfully completing your operation
