后WITH已被指定（超出右括号），您需要选择从CTE的所有值：

select * from xxDirectReports

这是构成视图的实际选择查询。

这是一个完整的工作示例，其中选择了视图的最终输出，以及一些其他GO语句，以允许这些语句在SQL Server Management
Studio中一次执行即可运行：

if not OBJECT_ID('XHR_PERSON', 'Table') is null drop table XHR_PERSON
if not OBJECT_ID('XHR_EMPLOYMENT', 'Table') is null drop table XHR_EMPLOYMENT
if not OBJECT_ID('HR_DIRECTREPORTSV', 'View') is null drop view HR_DIRECTREPORTSV

CREATE TABLE [dbo].[XHR_PERSON](
[PERSON_ID] [bigint] NOT NULL,
[LAST_NAME] [varchar](100) NOT NULL,
[FIRST_NAME] [varchar](100)
,EFFECTIVE_START_DATE Date
,EFFECTIVE_END_DATE Date)

CREATE TABLE [dbo].[XHR_EMPLOYMENT](
[PERSON_ID] [bigint] NOT NULL,
[EMPLOYEE_NUMBER] [varchar](100) NULL,
[SUPERVISOR_ID] [bigint] NULL
,EFFECTIVE_START_DATE Date
,EFFECTIVE_END_DATE Date)

insert into XHR_PERSON

另外，是否可以基于样本数据LFG而不是SMY来获取以开头的记录？

是的！尽管方法各不相同。 我建议在CTE的锚定语句中包含一个变量，而不是使用视图，而是将其创建为表值函数
。但是，一旦假定采用分层形式，就可以采用多种不同的方法来选择分层数据。方法之一是 Hierarchical Path 。

要添加此行为，请Path在WITH子句中添加列名，然后首先在anchor语句中添加以下内容：

convert(nvarchar(256), RTRIM(convert(nvarchar(12), hre.PERSON_ID))) Path

其次，在递归语句中：

convert(nvarchar(256), rtrim(Path) + '.' + RTRIM(convert(nvarchar(12), hre.PERSON_ID))) Path

然后，要选择层次结构根（LFG）和所有下属，只需将从视图中选择的查询修改为此：

select * from HR_DIRECTREPORTSV
where Path = '3' or Path like '3.%'

结果如下：

Path   Supervisor_id   Person_id   Employee_number   Employee_name   Supervisor_Empno   Supervisor_Name   Level1
3   1   3   333 LFG, A  111 SMY, A  0
3.7 3   7   777 Teddy, A    333 LFG, A  1
3.8 3   8   888 Alex, A 333 LFG, A  1
3.8.9   8   9   999 Jeff, A 888 Alex, A 2
