通过使用SQL Server这样的说法：
EXEC sp_msforeachtable 'DROP TABLE ?'
我知道这是可以一次删除所有表。
是否有意见了类似的声明？ 我想这希望是幸运的：“？DROP VIEW” EXEC sp_msforeachview 但它不工作！
Answer 1:
在这里，你有没有需要光标：
DECLARE @sql VARCHAR(MAX) = ''
, @crlf VARCHAR(2) = CHAR(13) + CHAR(10) ;
SELECT @sql = @sql + 'DROP VIEW ' + QUOTENAME(SCHEMA_NAME(schema_id)) + '.' + QUOTENAME(v.name) +';' + @crlf
FROM sys.views v
PRINT @sql;
EXEC(@sql);
Answer 2:
declare @SQL nvarchar(max)
set @SQL =
(
select 'drop view '+name+'; '
from sys.views
for xml path('')
)
exec (@SQL)
Answer 3:
所有答案不占视图之间的约束。 这个脚本会考虑到这一点：
SET @schemeName = 'dbo'
SELECT @name =
(SELECT TOP 1 o.[name]
FROM sysobjects o
inner join sys.views v ON o.id = v.object_id
WHERE SCHEMA_NAME(v.schema_id) =@schemeName AND o.[type] = 'V' AND o.category = 0 AND o.[name] NOT IN
(
SELECT referenced_entity_name
FROM sys.sql_expression_dependencies AS sed
INNER JOIN sys.objects AS o ON sed.referencing_id = o.object_id
WHERE referenced_schema_name = @schemeName
)
ORDER BY [name])
WHILE @name IS NOT NULL
BEGIN
SELECT @SQL = 'DROP VIEW [' + @schemeName + '].[' + RTRIM(@name) +']'
EXEC (@SQL)
PRINT 'Dropped View: ' + @name
SELECT @name =
(SELECT TOP 1 o.[name]
FROM sysobjects o
inner join sys.views v ON o.id = v.object_id
WHERE SCHEMA_NAME(v.schema_id) = @schemeName AND o.[type] = 'V' AND o.category = 0 AND o.[name] NOT IN
(
SELECT referenced_entity_name
FROM sys.sql_expression_dependencies AS sed
INNER JOIN sys.objects AS o ON sed.referencing_id = o.object_id
WHERE referenced_schema_name = @schemeName
)
ORDER BY [name])
END
GO
这个循环到所有视图和选择TOP 1认为是不存在于参考SYSTABLE。
Answer 4:
我想一个脚本，删除绑定到架构的观点在正确的依赖顺序，我希望它在SQL Azure上运行，其中sys.dm_sql_referencing_entities不可用。 我也希望能够看到之前，我居然跑它正在运行的SQL - 你不能在由@RicNet答案脚本做。 所以我写了，这里使用其他的答案为基础这个递归查询
DECLARE @sql VARCHAR(MAX) = ''
DECLARE @crlf VARCHAR(2) = CHAR(13) + CHAR(10);
;WITH allviews as
( --just combining schema and name
SELECT
object_id,
'[' + SCHEMA_NAME(schema_id) + '].[' + name + ']' AS viewname
FROM sys.views
),
dependents AS
(
SELECT
referencing.viewname dependentname,
referenced.viewname dependenton
FROM sys.sql_expression_dependencies r
INNER JOIN allviews referencing
ON referencing.object_id = r.referencing_id
INNER JOIN allviews referenced
ON referenced.object_id = r.referenced_id
)
,
nodependents
AS
(
SELECT
viewname name
FROM allviews v
LEFT JOIN dependents d
ON d.dependentname = viewname
WHERE d.dependentname IS NULL
)
,hierarchy AS
( --the hierarchy recurses the dependencies
SELECT
d.dependenton,
d.dependentname,
1 tier
FROM dependents d UNION ALL SELECT
d.dependenton,
d.dependentname,
h.tier + 1
FROM dependents d
INNER JOIN hierarchy h
ON h.dependenton = d.dependentname
--best thing I could think to stop the recursion was to
--stop when we reached an item with no dependents
WHERE h.dependenton NOT IN (SELECT
name
FROM nodependents)
),
combined as
( --need to add item with no dependents back in
SELECT
0 tier,
name
FROM nodependents UNION SELECT
tier,
dependentname
FROM hierarchy
)
SELECT
@sql = @sql + 'DROP VIEW ' + name + ';' + @crlf
FROM combined
GROUP BY name --need to group because of multiple dependency paths
ORDER BY MAX(tier) desc
PRINT @sql;
--commented out until I'm confident I want to run it
--EXEC(@sql)
Answer 5:
试试这个脚本
DECLARE @viewName varchar(500)
DECLARE cur CURSOR
FOR SELECT [name] FROM sys.objects WHERE type = 'v'
OPEN cur
FETCH NEXT FROM cur INTO @viewName
WHILE @@fetch_status = 0
BEGIN
EXEC('DROP VIEW ' + @viewName)
FETCH NEXT FROM cur INTO @viewName
END
CLOSE cur
DEALLOCATE cur

Answer 6:
但有关架构是什么？
下面的脚本将帮助你，如果意见是模式的一部分
DECLARE @sql VARCHAR(MAX)='';
SELECT @sql=@sql+'DROP VIEW '+name +';' FROM
(
SELECT Name=[s].name + '.' + [v].name FROM sys.views [v]
LEFT OUTER JOIN sys.schemas [s]
ON
(
[v].[schema_id]=[s].[schema_id]
)
)
X
EXEC(@sql)
Answer 7:
由于没有从我的答案试图脚本的一个多模式的情况下工作正常，我包括一个工作之一。
--DBNAME, PUT YOU OWN ONE use SIPE_ISU
DECLARE @viewName VARCHAR（500）DECLARE CUR CURSOR FOR SELECT sk.name + '' + so.name FROM sys.objects中以便内部联接sys.schemas SK上sk.schema_id = so.schema_id WHERE类型= 'V' OPEN CUR FETCH NEXT FROM CUR INTO @viewName WHILE @@ FETCH_STATUS = 0 BEGIN EXEC（ 'DROP VIEW' + @viewName）FETCH NEXT FROM CUR INTO @viewName END CLOSE CUR DEALLOCATE CUR
Answer 8:
DECLARE @sql VARCHAR(MAX) = ''
, @crlf VARCHAR(2) = CHAR(13) + CHAR(10) ;
SELECT @sql = @sql + 'DROP VIEW ' + QUOTENAME(SCHEMA_NAME(schema_id)) + '.' + QUOTENAME(v.name) +';' + @crlf
FROM sys.views v
PRINT @sql;
EXEC(@sql);
