Linking Oracle view to SQL Server express

Hi,

I was able to link SQL Server Express to Oracle views using Linked Manager. However, when I run the query, the performance is very slow.

Is there a way to improve performance in querying?

Previously I was using Access to link to Oracle view. But the performance is not good. Takes about 8 hours for approx 6000 records.

Thanks a lot,

Stara

Which driver did you use ? Its long ago that I worked with Oracle linked servers, but you should use the Oracle driver which comes with the clint installation of Oracle rather than the MS one. You could also try to use an Openquery rather than the direct view as this statememt is directly executed on the Oracle system and is not further translated through the driver tier. Are you executing a complicate query whereas calculations are done on the Oracle or SQL Server side ?

I have used MSDAORA. How do I use OpenQuery. Can you please provide an example?

Thanks,

You are using the MS Oracle driver, as Jens suggestions you might consider using the driver provided by Oracle. You can find an example of using Openquery in BOL, the topic is here. When ever you're looking for an example of how to use a specific function, it's a good idea to search BOL first since all T-SQL commands are documented there.
