我有这些我想做的多个选择语句

CREATE VIEW dbo.vw_customers_addresses_services_servicetanks

这是我的选择声明：

SELECT * FROM Customers
     WHERE EXISTS
      (SELECT * FROM Addresses
       WHERE Addresses.OwnerId = Customers.Id
       AND Addresses.OwnerId = 97587
       AND Addresses.TenantId = 1013);


(SELECT * FROM Addresses
     WHERE Addresses.OwnerId = 97587
     AND Addresses.TenantId = 1013
     AND Addresses.Type = 'Delivery');


SELECT * FROM dbo.Services
     WHERE EXISTS
      (SELECT * FROM Addresses
       WHERE Addresses.Id = Services.AddressId
       AND Addresses.OwnerId = 97587
       AND Addresses.TenantId = 1013);

(SELECT ServiceTanks.*
     FROM ServiceTanks, Addresses, Services
      WHERE Services.Id = ServiceTanks.ServiceId
      AND Addresses.Id = Services.AddressId
      AND Addresses.OwnerId = 97587
      AND Addresses.Tenantid = 1013)

它现在作为一个多选语句工作。但是，我的目标是通过 SQL 视图修改数据，在其中我可以使用 SSMS 和 EDIT TOP X ROWS 的魔力从第三个选择语句对 AddressID RESULT 进行快速更新。

当我将 CREATE VIEW 放在第一个 select 语句上方时，它会给出一个红色的大波浪线，上面写着“语法错误：'CREATE VIEW' 必须是批处理中的唯一语句。”

我是在做梦还是可以像我描述的那样做到这一点？

文档... https://docs.microsoft.com/en-us/sql/relational-databases/views/modify-data-through-a-view

有关如何通过具有许多基础选择语句（表）的视图修改数据的代码示例。

--tables
if exists (select * from sys.tables where name = 'table1')
    drop table table1
go

if exists (select * from sys.tables where name = 'table2')
    drop table table2
go

create table table1 (tkey1 int identity(1,1), fk int, name varchar(32));
create table table2 (tkey2 int identity(1,1), name varchar(32));
--data
insert into table2 (name) values ('MS')
insert into table2 (name) values ('OSS')
insert into table2 (name) values ('Oracle')
insert into table1 (fk, name) values (3, 'SQL')
insert into table1 (fk, name) values (1, 'postgreSQL')
insert into table1 (fk, name) values (2, 'mySQL')
go

if exists (select * from sys.views where name ='vw')
    drop view vw
go
create view vw
as
select t1.tkey1, t1.fk, t1.name as t1_name, t2.tkey2, t2.name as t2_name from table1 t1 inner join table2 t2 on t1.fk = t2.tkey2
go

select * from vw
go

begin tran
update vw set fk = 2 where fk = 1
update vw set fk = 1 where fk = 3
update vw set fk = 3 where fk = 2
select * from vw
rollback tran

begin tran
update vw set t2_name = 'OSS' where fk = 1
update vw set t2_name = 'MS' where fk = 3
update vw set t2_name = 'Oracle' where fk = 2
select * from vw
commit tran
