I've searched around for an answer to this, but have thus far been unsuccessful finding something that works for me.
I am attempting to connect to an Oracle database in an SSRS report within VS2008, but always get the following error:
System.Data.OracleClient requires Oracle client software version 8.1.7 or greater
I'm guessing it is a configuration issue (I have 11g client stuff installed on my system), but I can't seem to figure it out. The connection string also appears to be correct, as it works correctly on other machines.
In case this helps someone in the future, I will answer it here instead of deleting the question.
I had multiple versions of Oracle installed on this PC, some added by another user (it's a work laptop that I inherited and no control of what was installed previously).
I had to uninstall and reinstall the Oracle client (I chose the 11g R2 Client). At that point, everything appears to have been cleaned up, and I can run SSRS inside VS2008.
