I had asked this a while back but I think my query got Warnocked.

I would like to create a TRIGGER (or a CONSTRAINT) that throws an
error if an UPDATE query is run *without* a WHERE clause. This would
prevent accidentally mucking up the entire database, which, believe
you me, I have done more than once, and have been saved only by the
magic of Time Machine.

The TRIGGER would allow a full UPDATE of the table only by using some
special syntax in the query... like say, by adding something like
WHERE 0=0;
