CREATE VIEW 必须是批处理 MS SQL Server 中的唯一语句

Question

Microsoft SQL Server Management Studio 18 显示错误：

CREATE VIEW 必须是批处理中的唯一语句

执行请求后，出现如下错误：

“select”关键字周围的语法不正确

create view revenue0 (supplier_no, total_revenue) as
    select
        l_suppkey,
        sum(l_extendedprice * (1 - l_discount))
    from
        lineitem
    where
        l_shipdate >= '1996-05-01'
        and l_shipdate < dateadd(mm,3,cast('1996-05-01' as datetime))
    group by
        l_suppkey;


select
s_suppkey,
s_name,
s_address,
s_phone,
total_revenue
from
supplier,
revenue0
where
    s_suppkey = supplier_no
    and total_revenue = (
        select
            max(total_revenue)
        from
            revenue0
    )
order by
s_suppkey
option (maxdop 2)
drop view revenue0

UPD。我尝试使用这种方法运行：

create view revenue0 (supplier_no, total_revenue) as
    select
        l_suppkey,
        sum(l_extendedprice * (1 - l_discount))
    from
        lineitem
    where
        l_shipdate >= cast('1996-05-01' as datetime)
        and l_shipdate < dateadd(mm, 3, cast('1996-05-01' as datetime))
    group by
        l_suppkey;

go
select
    s_suppkey,
    s_name,
    s_address,
    s_phone,
    total_revenue
from
    supplier,
    revenue0
where
    s_suppkey = supplier_no
    and total_revenue = (
        select
            max(total_revenue)
        from
            revenue0
    )
order by
    s_suppkey;

drop view revenue0;

但是作为执行请求的结果，显示错误： 无效的对象名称“revenue0”。 只要我没有改名。 SQL 都以这个名字发誓。

UPD2。这个问题是独立解决的。话题已关闭！谢谢大家的努力！

错误告诉您 CREATE VIEW 必须是批处理中的唯一语句。正如 Gordon 所说，批处理在 SQL Server 中以“GO”关键字结束，因此您的代码应如下所示：

create view revenue0 (supplier_no, total_revenue) as
    select
        l_suppkey,
        sum(l_extendedprice * (1 - l_discount))
    from
        lineitem
    where
        l_shipdate >= '1996-05-01'
        and l_shipdate < dateadd(mm,3,cast('1996-05-01' as datetime))
    group by
        l_suppkey;

GO -- right here. This ends a batch. Must be on a new line, with no semi-color, or SQL gets pissy. 

select
    s_suppkey,
    s_name,
    s_address,
    s_phone,
    total_revenue
from
    supplier,
    revenue0
where
    s_suppkey = supplier_no
    and total_revenue = (
        select
            max(total_revenue)
        from
            revenue0
    )
order by
    s_suppkey
option (maxdop 2); 

drop view revenue0;
