    Hi

    I need to update several tables which have the same field its a shopid.

    e.g.

    Update orders set Shopid =300 where shopid =3

    Shopid is part of indices.

    Will it make a big difference to disable the indices first.

    I'm concerned about log file getting too big for the disk.

    Thanks

    if you disable the indexes, everything will slow down, because it has to do a table scan instead of an index seek to update the table, right?

    your example is probably an over simplification of a real problem, maybe you can add some detail as to what the underlying problem is?
