¿Alguien ha escrito o sabe de una consulta que encontrará y descartará todas las propiedades extendidas (Base de datos, tabla y nivel de columna) que tienen un nombre de pila? Sé que puedo soltar una propiedad extendida a través del procedimiento almacenado sp_dropextendedproperty.Consulta para soltar todas las propiedades extendidas que contienen un cierto nombre
Un enlace a algo que puede ser útil para usted. http://social.msdn.microsoft.com/Forums/en/transactsql/thread/747cb7c2-b176-4f75-9d92-c5a9360b4ed3
Genera una declaración spc ddpextendedproperty del ejecutor dinámico para cada propiedad encontrada.
Para mí, la secuencia de comandos en el enlace de Mikael no creaba caídas para todas las propiedades extendidas, p. los de las vistas Lo que funcionó fue un script creado por Jamie Thomson, que puedes descargar de este article.
he pegado aquí su guión (en su totalidad con los acuses de recibo, en el caso se elimina el artículo):

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:

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.

sys.functions no existe. ¿Qué versión de SQLServer está ejecutando? – TheLegendaryCopyCoder
Las respuestas anteriores no funcionaron correctamente para mí; no eliminaron las propiedades extendidas para desencadenantes de bases de datos, colecciones de esquemas xml o índices. Encontré esto script to delete extended properties (comentarios traducidos del japonés usando Google translate), que funcionó perfectamente para mí.
Advertencia: este realidad elimina todas las propiedades extendidas, en lugar de dar salida a una consulta para hacerlo, ya que las respuestas anteriores hacen. Para cambiar el comportamiento para generar una consulta en su lugar, cambie cada EXEC (@sql) a PRINT (@sql).
