我尝试运行一个脚本，为特定数据库的每个表创建一个视图。 我找到了这个链接： How to create view for all tables in database?
显然，为了工作，我需要添加“GO＆＃39;声明和回车。所以这就是我做的事情DECLARE @SQL NVARCHAR(MAX)
SET @SQL = ''
SELECT
@SQL = @SQL+
N'CREATE VIEW [v2_' + t.name + N'] AS SELECT ' +
STUFF(
(SELECT N',' + c.name
FROM
sys.columns AS c
WHERE
c.OBJECT_ID = t.OBJECT_ID
ORDER BY
column_id
FOR XML PATH(''), TYPE).value('.',N'nvarchar(max)')
,1,1,N'')
+ N' FROM [' + t.name + N'] [\r\n]go[\r\n]'
FROM
sys.tables AS t
WHERE
t.schema_id ='1'
SET @SQL = REPLACE(@SQL,'[\r\n]',CHAR(13)+CHAR(10))
PRINT @SQL
EXECUTE (@SQL)
因此打印结果符合我的预期：
CREATE VIEW ***** AS SELECT Parent_Path,id,a2ea,userLabel,DATE,HEURE,REF_EQT,COMMANDE_REF,LOG FROM *****
go
CREATE VIEW ***** AS SELECT AlarmIdentifier,Class,Category,Time,ObjectOfReference,AlarmText,DATE,HEURE,REF_EQT,SS_EQT,Carte_EQT,COMMANDE_REF,LOG FROM *****
go
CREATE VIEW ***** AS SELECT CELL,MCC,MNC,LAC,CID,BSC,CO,EA,RO,NCS,DATE,HEURE,REF_EQT,SS_EQT,Carte_EQT,COMMANDE_REF,LOG FROM *****
go
CREATE VIEW ***** AS SELECT RNC,RNCID,R1,R2,GLCNID,RNCCODEC,TB,DATE,HEURE,REF_EQT,SS_EQT,Carte_EQT,COMMANDE_REF,LOG FROM *****
go
CREATE VIEW ***** AS SELECT MGG,MG,RESTRICTED,DEFAULT,MISC,MGP,WF,DATE,HEURE,REF_EQT,SS_EQT,Carte_EQT,COMMANDE_REF,LOG FROM [NRGGP]
go
CREATE VIEW ***** AS SELECT SNT,SNTV,SNTP,DIP,DEV,DEVP,SNTINL,EQLEV,PROT,SDIP,SUBSNT,DEFPST,EXTP,MG,DATE,HEURE,REF_EQT,COMMANDE_REF,LOG FROM *****
go
CREATE VIEW ***** AS SELECT RefreshLog_Id,Date,Etat,DateTransfert,Transfert FROM *****
go
但是exec行返回：
Msg 156，Level 15，State 1，Procedure *****，Line 3 [Batch Start Line 0]
附近的语法不正确
关键字＆＃39; CREATE＆＃39;。Msg 111，Level 15，State 1，Procedure *****，Line 3 [Batch Start Line 0]
＆＃39;创建视图＆＃39;必须是查询批处理中的第一个语句。Msg 111，Level 15，State 1，Procedure *****，Line 5 [Batch Start Line 0]
＆＃39;创建视图＆＃39;必须是查询批处理中的第一个语句。Msg 111，Level 15，State 1，Procedure *****，Line 7 [Batch Start Line 0]
我应该创建架构吗？我问题的任何解决方案？
非常感谢

使用光标并执行 sp_executesql 似乎可以正常工作
DECLARE @SQL NVARCHAR(MAX)
, @table_id INT
SET @SQL = ''
DECLARE CUR CURSOR LOCAL FAST_FORWARD FOR
SELECT t.object_id FROM sys.tables AS t
WHERE t.schema_id ='1'
OPEN CUR
FETCH NEXT FROM cur INTO @table_id
WHILE @@FETCH_STATUS = 0
BEGIN
SELECT @SQL = N'CREATE VIEW [v2_' + t.name + N'] AS SELECT ' +
STUFF(
(SELECT N',' + c.name
FROM
sys.columns AS c
WHERE
c.OBJECT_ID = t.OBJECT_ID
ORDER BY
column_id
FOR XML PATH(''), TYPE).value('.',N'nvarchar(max)')
,1,1,N'')
+ N' FROM [' + t.name + N'];'
FROM
sys.tables AS t
WHERE t.object_id = @table_id
PRINT @SQL
--EXECUTE sp_executesql @SQL
FETCH NEXT FROM cur INTO @table_id
END
CLOSE CUR
DEALLOCATE CUR

好的，最后我做了你们建议的，我创建了一个光标，它可以工作。谢谢。
DECLARE @TableName as NVARCHAR(50)
DECLARE @TableCursor as CURSOR
SET @TableCursor = CURSOR FOR
SELECT TABLE_NAME
FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_TYPE='BASE TABLE' and TABLE_SCHEMA = 'dbo';
OPEN @TableCursor;
FETCH NEXT FROM @TableCursor INTO @TableName;
While @@FETCH_STATUS = 0
BEGIN
EXEC ('create view '+ @TableName+'_V2
as select * from ' +@TableName +';')
FETCH NEXT FROM @TableCursor INTO @TableName;
END
CLOSE @TableCursor
DEALLOCATE @TableCursor

您应该使用这样的语法：
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE VIEW [schema].[viewname] AS
SELECT * FROM schema.table
GO
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE VIEW [schema].[viewname] AS
SELECT * FROM schema.table
GO
例如：
SELECT
'SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE VIEW ' + TABLE_SCHEMA + '.' + TABLE_NAME + ' AS
SELECT * FROM ' + TABLE_SCHEMA + '.' + TABLE_NAME + '
GO
'
FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_TYPE='BASE TABLE'
别忘了以文本格式（在SQL Server Mgmt studio中为CTRL + T）输出结果，因为它将保留回车符。
对于这种情况，您可以生成一个脚本来检查SQL Server如何处理您的脚本。 只需右键单击数据库，“任务”，“生成脚本”并跟随助手。它将完全在SQL Server等待时为您输出文件。
