The way you get around this in ANSI/ISO Standard SQL is with the
CREATE ASSERTION statement. It is a CHECK() done at the schema level
instead of the table level. That is why CONSTRAINT names are globla
and noyt local to their table.

CREATE ASSERTION NotEmpty
CHECK ((SELECT COUNT(*) FROM Foobar) > 0);
