Löschen Sie alle erweiterten Eigenschaften auf SQL Server

Question

Wie Sie alle erweiterten Eigenschaften auf SQL Server auf eine skriptfähige Weise löschen?

Answer 1

sehen Sie bitte die folgende URL, um die erweiterte Eigenschaft löschen:

http://msdn.microsoft.com/en-us/library/ms178595.aspx

Answer 2

Verwendung dieses Skript

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

Quelle: drop extended property

Answer 3

Wenn Sie ein Skript wollen, dass alle sinkt erweiterte Eigenschaften auf einmal verwenden Sie dann ein Skript, das Jamie Thomson erstellt hat, das Tropfen für alle erweiterten Eigenschaften erzeugt. Sie können es von dieser article herunterladen.

Ich habe das Drehbuch hier eingefügt (in voller Höhe mit Bestätigungen im Fall der Artikel entfernt wird):

/* 
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.

Answer 4

Ich habe versucht, die Skripte laufen und nichts schien für mich zu arbeiten. Ich fand aber, dass ich, indem Sie auf meine Tabellen/Ansichten in Object Explorer und tun, um im Anschluss an die erweiterten Eigenschaften löschen könnte:

• Rechtsklick auf Tabelle/Blick in Objekt-Explorer, wählen Sie Eigenschaften
• Wählen Sie Erweiterte Eigenschaften aus Wählen Sie die Scheibe auf der linken Seite
• die erweiterten Eigenschaften und klicken Sie auf löschen in der rechten unteren Ecke des Fensters
