Question

Come eliminare tutte le proprietà estese su SQL Server in modo scriptable?

Answer 1

prega di consultare il seguente URL per eliminare la proprietà estesa:

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

Answer 2

uso questo script

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

Fonte: drop extended property

Answer 3

Se si desidera uno script che scenderà tutto Proprietà estese in un colpo solo, quindi utilizzare uno script creato da Jamie Thomson che genererà gocce per tutte le proprietà estese. È possibile scaricarlo da questo article.

Ho incollato suo script qui (in pieno con riconoscimenti nel caso l'articolo viene rimosso):

/* 
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

Ho provato a eseguire gli script e nulla sembrava funzionare per me. tuttavia ho trovato che avrei potuto eliminare le proprietà estese andando ai miei tabelle/viste in Object Explorer e facendo per seguenti:

• clic destro sulla tabella/vista in Esplora oggetti, selezionare Proprietà
• selezionare Proprietà estese da riquadro a sinistra
• Selezionare le proprietà estese e fare clic su Elimina in basso a destra della finestra
