database A is in full recovery model and the log for that database is log A.
database B is in Bulk logged recovery model and the log for that database is log B

suppose a bulk operation of 2000 record is performed on both databases A and B.

Then my doubt is both logs A and B have the same information , but point in time recovery is only possible for database A and it is not possible for database B.
Plz guide me

To the best of my knowledge, point of time recovery that includes bulk inserts, is possible only with FULL RECOVERY... and then only if you're backing up the log very frequently.

Thanks for your answer.

I want to know whether log A and log B has the same transactions or not

Maybe yes, maybe no... the Bulk Insert has to meet certain requirements to NOT be logged. Check for "Recovery Model" in Books Online for more information on the recovery models... see the following BOL url for more information on whether something get's minimally logged or not...

ms-help://MS.SQLCC.v9/MS.SQLSVR.v9.en/udb9/html/bd1dac6b-6ef8-4735-ad4e-67bb42dc4f66.htm

(Past the above into the BOL url field...)
