| For performance should we index on primary key & data in table in the same file group or different file group (same or different drive) ?Thanks,Andy |

| As far as performance is concerned the PK is no different to other indexes.If you mean a clustered index then there's no choice.It's probably faster to have the index on a separate drive to the data but may well be overridden by other factors.==========================================Cursors are useful if you don't know sql.DTS can be used in a similar way.Beer is not cold and it isn't fizzy. |

i would expand by saying it is almost always faster to do it this way. |
