locking

  Hi,

   I'm trying to figgure out how does the locking work.

  If I get a ``Result Table'' from a select with, say, only one row which
comes from only one ``Schema Table'', and I lock the ``Result Table'',
will it not prevent updates of the row in ``Schema Table'' that appeared 
in the ``Result Table'' ? 

   Thanx,

       Jan
