如何以脚本方式删除SQL Server上的所有扩展属性？
答案 0 :(得分：17)
如果你想要一个将一次性删除所有扩展属性的脚本，那么使用Jamie Thomson创建的脚本将为所有扩展属性生成丢弃。您可以从此article下载。
我已经在这里粘贴了他的剧本（如果文章被删除，请完整填写确认信息）：
/*
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.

使用此脚本
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，似乎没有什么对我有用。但我发现我可以通过转到Object Explorer中的表格/视图并执行以下操作来删除扩展属性：
