If you are executing a simple SQL query like
SELECT * FROM Articles
against an Oracle database from within a .NET application and you are getting an exception like
System.DivideByZeroException: Attempted to divide by zero.
System.DivideByZeroException: Es wurde versucht, durch 0 (null) zu teilen.
Probably a bug in the ODAC .NET drivers/layers. One user in the Oracle forums faced the same issue.
In my case it was as simple as replacing the asterisk (“*”) with an explicit list of columns I wanted to query for.
SELECT Name1, Price, Description FROM Articles
After that modification, I was successfully able to run the query and get results.
