将schema :: xxx上的授权更改为[Domain \ user1]无法授予架构权限？

Question

以下SQL出现了权限拒绝错误。

drop schema xxx; -- run if xxx exists
go
create schema xxx;
go
alter authorization on schema::xxxto [Domain\user1]
exec ('create view xxx.x as select 1 a') as login = 'Domain\user1'
go

  

数据库'....'中的CREATE VIEW权限被拒绝

随后的错误也得到了相同的错误。

drop schema xxx;
go
create schema xxx;
go
GRANT CONTROL ON SCHEMA::[xxx] TO [Domain\user1]
exec ('create view xxx.x as select 1 a') as login = 'Domain\user1'
go

为什么不起作用？
