Drop all column extended propterties

Need help with admin scripts.

Have written stored procs to insert/update/drop column extended props but can't quite figure out how to drop all extended props for a particular table::column.

Tried stored proc to cursor on result

fn_listextendedproperty

but couldn't get that to work.

Where are xtended props stored in db?

This will work. Never touch the system tables, and it is not even reasonable to do it in 2005. This will work (I will leave it to you to parameterize):

CREATE TABLE T1 (id int , name char (20));
GO
EXEC sp_addextendedproperty 'caption', 'Employee ID', 'schema', dbo, 'table', 'T1', 'column', id;
GO
EXEC sp_addextendedproperty 'schmaption', 'Employee ID', 'schema', dbo, 'table', 'T1', 'column', id;
GO

select name
from fn_listextendedproperty(NULL, 'schema','dbo','table','T1','column','id')

declare @.cursor cursor, @.property sysname
set @.cursor = cursor for
select name
from fn_listextendedproperty(NULL, 'schema','dbo','table','T1','column','id')
open @.cursor

while (1=1)
begin
fetch next from @.cursor into @.property

if @.@.fetch_status <> 0 break

EXEC sp_dropextendedproperty @.property, 'schema', dbo, 'table', 'T1', 'column', id;
end

select name
from fn_listextendedproperty(NULL, 'schema','dbo','table','T1','column','id')

GO
DROP TABLE T1;
GO
