    SQL Server + Oracle Data linked in one query

    I need to link some data from SQL Server 2005 with Oracle 10 data.

    One way is to link Oracle server to SQL Server and use ROWSOURCE for
    retrieving data.

    What other ways for joing data from both databases exist ?

    Can I do it from SQLCRL VB - Stored Procedure ? If yes, what objects
    shall I use for opening database and running an sql ?

    Thanks a lot.

      I know it's a similiar concept but how about via linked servers?

          Thanks Mark, I tried the linked servers. I have read permission on
          oracle tables (from VB .NET I have no problem executing queries on
          tables and retrieving data) but when I execute

          select * from RAS...PRODUCT

          I get the error "The OLE DB provider "MSDAORA" for linked server "RAS"
          does not contain the table "COUNTRY". The table either does not exist
          or the current user does not have permissions on that table.

          For exec sp_tables_ex 'RAS','product'

          NULL MyUser PRODUCT SYNONYM NULL

          Do I need different permissions for linked server ?

              The error appeared because I defined schema name in lowercase.
