    You mean LOB (Large OBjects)?

    LOB data types are text, ntext, image, varchar(max), nvarchar(max), varbinary(max), xml and large CLR types.

    I'm surprised Gail and Jeff haven't jumped all over this but that does not look like a good candidate for a clustered index, its certainly not narrow or ever-increasing.

    Changing the cluster could save some of that 10GB down to indexes (you only have a clustered index?) and reduce the occurrence of fragmentation in the first place.

    Heh... peeling one potato at a time.

    RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
    First step towards the paradigm shift of writing Set Based code:
    ________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

    Change is inevitable... Change for the better is not.
