No, that just hides any bugs. We want the opposite: any bugs or
problems should be obvious. If the query returns or touches more than
one row, that should raise an error, not just give you a random one and
call it a day.
That already solves the purported problem of multiple results in SELECT
INTO as well. Could we possibly extend that to UPDATE and DELETE syntax too?
Again, this is a different problem, but LIMIT syntax for UPDATE and
DELETE has been proposed, see:
