nhibernate QueryOver でこれを行う必要があります。

select distinct sc.* from [Security].[Commands] sc
inner join [Security].[SystemSubjects] ss on ss.Id = sc.Id
left outer join [Security].[SystemSubjectRoles] ssr on ssr.SystemSubjectId = ss.Id
left outer join [Security].[Roles] sr on sr.Id = ssr.RoleId
left outer join [Security].[UserRoles] ur on ur.IdRole = sr.Id 
left outer join [Security].[User] su2 on su2.Id = ur.IdUser
left outer join [Security].SystemSubjectUsers ssu on ssu.SystemSubjectId = ss.Id
left outer join [Security].[User] su on su.Id = ssu.UserId
where (su2.Id = 1 or su.Id = 1)

これまでのところ、私はこれを行ってきました：

var queryOverRoles = QueryOver.Of<Command>(() => cmdAlias)
            .JoinAlias(() => cmdAlias.SystemSubjectRoles, () => ssRoleAlias, JoinType.LeftOuterJoin)
            .JoinAlias(() => ssRoleAlias.Role, () => roleAlias, JoinType.LeftOuterJoin)
            .JoinAlias(() => roleAlias.Users, () => userAlias, JoinType.LeftOuterJoin)
            .JoinAlias(() => cmdAlias.SystemSubjectUsers, () => ssUserAlias, JoinType.LeftOuterJoin)
            .JoinAlias(() => ssUserAlias.User, () => userAlias2, JoinType.LeftOuterJoin)
            .TransformUsing(Transformers.DistinctRootEntity)
            .Where(() => ssRoleAlias.SecurityPermission == SecurityPermission.Allow)
            .And(() => (userAlias.Id == userId || userAlias2.Id == userId))

しかし、これはすべてを選択し（ Select ）、 Command オブジェクトのみが必要です（ select sc.）。次のようにクエリにプロジェクションを追加しようとすると:

queryOverRole.Select(x=>x);

次の例外がスローされます。

System.Exception was caught   Message=Could not determine member

これを試してください....選択するエイリアスを指定する必要があります。queryOverRole.Select(result => cmdAlias);
