联合查询的结果作为其他查询的数据表时需要别名

/****** Script for SelectTopNRows command from SSMS ******/

select * from (

SELECT [Id]
,[AuditType]
,[AuditStepName]
,[AuditDocumentNo]
,[AudiDataCreatedBy]
,[AudiDataCreatedDate]
,[Auditusernam]
,[AuditStatus]
FROM [ZhiDuoTong_Factory].[dbo].[vAuditData]
union
SELECT [Id]
,[AuditType]
,[AuditStepName]
,[AuditDocumentNo]
,[AuditDataCreateBy]
,[AuditDataCreateDate]
,[Audituserman]
,[AuditStatus]
FROM [ZhiDuoTong_Factory].[dbo].[vHasAuditData]

)

显示结果：

消息 102，级别 15，状态 1，第 25 行
')' 附近有语法错误。

正确的写法：

create view vAuditAllRecords
as
(
select * from (
SELECT [Id]
,[AuditType]
,[AuditStepName]
,[AuditDocumentNo]
,[AudiDataCreatedBy]
,[AudiDataCreatedDate]

FROM [ZhiDuoTong_Factory].[dbo].[vAuditData]
union
SELECT [Id]

FROM [ZhiDuoTong_Factory].[dbo].[vHasAuditData]
