Ticket #34701 – Description
initial v1 3 3 While most backends default to implicit `NULLS DISTINCT` some backends don't, most notably SQL Server (cff59bedc23fd4d53557f677ddc42402b56963d0). 4 4 5 I suggest we add a `nulls_distinct: 5 I suggest we add a `nulls_distinct:Optional[bool]=None` option to `UniqueConstraint` so it preserves it's ''default to backend treatment of nulls'' behaviour while allowing it to be set explicitly on backends that support it. 6 6 7 7 - [https://modern-sql.com/caniuse/unique-nulls-not-distinct Article on the subject]
