Ако искате скрипт, който ще премахне всички разширени свойства наведнъж, тогава използвайте скрипт, създаден от Джейми Томсън, който ще генерира премахвания за всички разширени свойства. Можете да го изтеглите от този статия .
Поставих неговия скрипт тук (изцяло с благодарности в случай, че статията бъде премахната):
/*
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.
