  • Ticket #34701 – Description

    initial v1  
    33While most backends default to implicit `NULLS DISTINCT` some backends don't, most notably SQL Server (cff59bedc23fd4d53557f677ddc42402b56963d0).

    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.
