@Adrian -
Using a unique key value or otherwise isolating a specific record via
selection against values in its attributes is certainly preferable to
choosing a row to update via its position in a result set, unless the
use case actually makes use of that position info as a meaningful
descriptor of the data in some fashion.
The bigger issue is deciding what attribute of the selected row is be
used to do the UPDATE. Unless it is the PRIMARY KEY(or other UNIQUE
key(s)) then you very likely are going to UPDATE more then you bargained
for.
