Hi, Which Edition of SQL Server do we have to buy the SQL Server in order to use the SSRS feature to use with Oracle DB as the backend ? or it can be installed as freeware runtime components / services only ?

By using Microsoft SQL Server 2008 R2 Report Builder 3.0 from: http://www.microsoft.com/downloads/en/details.aspx?FamilyID=d3173a87-7c0d-40cc-a408-3d1a43ae4e33&displaylang=en Can I query and create report from Oracle DB for free ? the reason is that the price is too high to get full blown SQL Server just for reporting. /* Infrastructure Support Engineer */

Hi Albert, The Microsofot SQL Server 2008 R2 Report Builder 3.0 is a free client tool to author reports. It is able to connect to Oracle Database. However, the reports must be published to a report server. Not all edition of Report Server supports Oracle datasource. I would suggest you using Standard or Enterprise edition in this case.
