如果您想要一个脚本一次性删除所有扩展属性，请使用 Jamie Thomson 创建的脚本，该脚本将为所有扩展属性生成删除。您可以从这篇文章下载它。

我已将他的脚本粘贴在这里（完整的致谢，以防文章被删除）：

/*
This script will generate calls to sp_dropextendedproperty for every
extended property that exists in your database.
Actually, a caveat: I don't promise that it will catch each and every 
extended property that exists, but I'm confident it will catch most of them!

It is based on this: 
http://blog.hongens.nl/2010/02/25/drop-all-extended-properties-in-a-mssql-database/ 
by Angelo Hongens.

Also had lots of help from this:
http://www.sqlservercentral.com/articles/Metadata/72609/
by Adam Aspin

Adam actually provides a script at that link to do something very similar
but when I ran it I got an error:
Msg 468, Level 16, State 9, Line 78
Cannot resolve the collation conflict between "Latin1_General_100_CS_AS" and "Latin1_General_CI_AS" in the equal to operation.

So I put together this version instead. 

Use at your own risk.

使用这个脚本

EXEC sys.sp_dropextendedproperty 
     @name  =N'MS_Description', 
     @level0type = N'SCHEMA', 
     @level0name = N'dbo',
     @level1type = N'TABLE',
     @level1name = N'ActivityEventRecipient';
GO

我尝试运行脚本，但似乎没有任何效果。然而，我确实发现我可以通过转到

Object Explorer
中的表/视图并执行以下操作来删除扩展属性：

  • 右键单击对象资源管理器中的表/视图，选择属性
  • 从左侧窗格中选择扩展属性
  • 选择扩展属性，然后单击窗口右下角的删除

无法添加评论，我只能将其添加为答案。

对于视图列，脚本是错误的。列部分应更改为：

--columns
select 'EXEC sp_dropextendedproperty
@name = '''+sys.extended_properties.name+'''
,@level0type = ''schema''
,@level0name = ''' + object_schema_name(extended_properties.major_id) + '''

                             'table'
                         When 'v'
                             Then
                             'view'

You need to add this block for functions
UNION
-- functions
select 'EXEC sp_dropextendedproperty
@name = '''+xp.name+'''
,@level0type = ''schema''
,@level0name = ''' + object_schema_name(xp.major_id) + '''
,@level1type = ''function''
,@level1name = ''' + object_name(xp.major_id) + ''''
from sys.extended_properties xp
join sys.objects t ON xp.major_id = t.object_id AND t.type IN ('FN', 'IF', 'TF')  
where xp.class_desc = 'OBJECT_OR_COLUMN'
and xp.minor_id = 0;
UNION
-- for synonyms
select 'EXEC sp_dropextendedproperty
@name = '''+xp.name+'''
,@level0type = ''schema''
,@level0name = ''' + object_schema_name(xp.major_id) + '''
,@level1type = ''synonym''
,@level1name = ''' + object_name(xp.major_id) + ''''

此脚本与其他 anwsers 类似，允许您检查和过滤扩展属性： 只需在最后添加一个where子句即可
