if exists (select * from sysobjects where type = 'P' and name = 'sp_valid_oledb_provider')<BR/>
drop proc sp_valid_oledb_provider<BR/>
go
create proc sp_valid_oledb_provider @p nvarchar(255) as
set nocount on
create table #t([Provider Name] nvarchar(255) not null,[Parse Name] nvarchar(255) not null,[Provider Description] nvarchar(255) not null)
insert into #t exec xp_enum_oledb_providers
if exists (select * from #t where [Provider Name] = @p)
begin
   -- print 'OK'
   return 1
end

   raiserror('Invalid OLE-DB provider "%s"',-1, -1, @p)
