And the following is thanks to Brett Rosen : I noticed that you didn''''t have an OCI entry
on http://osi.oracle.com/~tkyte/ResultSets/index.html .
Here is OCI code to do this (Oracle 81) if you want to include it on
that page.
Some error checking and cleanup has been removed, but the below should
work. (once dbname has been replaced appropriately)
