    Hi,

    What is the main Difference between DBCC CHECKDB & DBCC CHECKDB WITH DATAPURITY?

    DBCC CHECKDB verifies the database consistency, torn page detection and page corruption.

    what DBCC CHECKDB WITH DATAPURITY do differently from DBCC CHECKDB db_name with no_infomsgs

    Thanks

    On a database created on 2005 or 2008, no difference at all. On databases created on those versions, data purity checks are done by default.

    On a database created on 2000 (or before) and upgraded, that option forces the data purity checks (see Books Online for details) as those checks are not done by default until a data purity check has run successfully.
