"Cannot create an instance of OLE DB provider" error as Windows Authentication user
I am trying to run openrowset from MS SQL Server on an Oracle server.
When i execute the following command:
select * from
OPENROWSET('OraOLEDB.Oracle','srv';'user';'pass',
'select * from table')
the following error occurs
Msg 7302, Level 16, State 1, Line 1
Cannot create an instance of OLE DB provider "OraOLEDB.Oracle" for linked server "(null)".
Can anyone tell me how I can use openrowset with OraOLEDB.Oracle?
I am using 64 bit version of MS SQL Server and Oracle OLEDB driver.
Edit
I have tried this on two machines running Windows 7 x64 & Windows Server 2008 x64 with MS SQL Server 2008 x64. Both showed the same error message.
Answer
In SQL Server Enterprise Manager, open \Server Objects\Linked Servers\Providers, right click on the OraOLEDB.Oracle provider, select properties and check the "Allow inprocess" option. Recreate your linked server and test again.
You can also execute the following query if you don't have access to SQL Server Management Studio :
EXEC master.dbo.sp_MSset_oledb_prop N'OraOLEDB.Oracle', N'AllowInProcess', 1
