Thus compromise between usability and perfection is the MSSQL-specific
-L<resultset attribute|DBIx::Class::ResultSet/ATTRIBUTES> C<unsafe_subselect>.
+L<resultset attribute|DBIx::Class::ResultSet/ATTRIBUTES> C<unsafe_subselect_ok>.
It is deliberately not possible to set this on the Storage level, as the user
should inspect (and preferrably regression-test) the return of every such
ResultSet individually. The example above would work if written like:
