Meh. Then you could have a query that works fine until you add a column
to the table, and it stops working. If nobody ever used column names
identical to table names it'd be all right, but unfortunately people
seem to do that a lot...
That's already the case with select statements
I don't think that's true if you table-qualify your column references
and don't use SELECT *.
and, if a user were
concerned about that, always have the option of aliasing the table as
nearly 100% of professional developers do:
SELECT f FROM foo f;
UPDATE foo f SET f = ..;
would resolve to the table, despite there being a column called "f"?
That would break backwards compatibility.
UPDATE foo SET ROW(foo) = (1,2,3);
ISTM that this could be parsed unambiguously, though it's perhaps a bit
