I'd be interested in hearing thoughts about changing the generated SQL for a negated equality comparison from using "!=" to "IS DISTINCT FROM" (where supported), since the latter has less-surprising handling of NULL values.
For example, with the following bit of AR: User.where.not(parent_id: 10) You would get some SQL roughly equivalent to: WHERE parent_id != 10 But this would not return rows where parent_id is NULL, since a comparison against NULL always returns NULL. This SQL would behave as we'd expect: WHERE parent_id IS DISTINCT FROM 10 Would there be any disadvantages to doing this sort of comparison by default?
