Jeśli potrzebujesz skryptu, który usunie wszystkie rozszerzone właściwości za jednym razem, użyj skryptu utworzonego przez Jamiego Thomsona, który będzie generował pominięcia dla wszystkich rozszerzonych właściwości. Możesz go pobrać z tego artykuł .
Wkleiłem tutaj jego skrypt (w całości z podziękowaniami na wypadek usunięcia artykułu):
/*
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.
