Query is way slower through ODBC compared to OLEDB

edited Feb 24, 2010 8:07PM in Windows Oracle Data Access Components (MOSC) 7 commentsAnswered
 I have an third party ASP webapplication that connects to an Oracle Database (10g)

The application executes a certain query to the Oracle Database.

If I set the application to use Oracle Oledb drivers, the query takes about 25 seconds.

If I set the application to connect through an ODBC connection however the query takes less than a second.

I've tried different versions of the oracle client but the problem remains.

In every topic I read, Oledb is prefered over ODBC, so i'm not keen on using ODBC as a solution to the problem.

Any clue on what might cause this huge difference is execution time?

Howdy, Stranger!
