MORE INFORMATION

xp_enum_oledb_providers returns three columns as follows:

ProviderName: Default value of CLSID key.
Parsename: CLSID (GUID).
Description: Friendly name of the provider.

Using this procedure, you can write another script or procedure to check if a specific provider is installed on a computer.

-- sp_valid_oledb_provider
-- A test to see if you pass in a legal provider name.
use master
go
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
else
begin
   raiserror('Invalid OLE-DB provider "%s"',-1, -1, @p)
   return 0<BR/>
end
go
exec sp_valid_oledb_provider N'SQLOLEDB'
exec sp_valid_oledb_provider N'MSDASQL'
exec sp_valid_oledb_provider N'Microsoft.Jet.OLEDB.4.0'
exec sp_valid_oledb_provider N'Illegal Provider'

This procedure can be used to find if a specific OLE DB provider is installed before setting up a SQL Server 7.0 distributed query with sp_addlinkedserver.
