I’m using the latest OCI8 lib and the Oracle instantclient 10. All  
works well until I try to interact with a table containing a  
binary\_double type field. I get: “RuntimeError: unsupported datatype:  
101”

Does OCI8 support the binary\_double datatype?

Thanks!  
Dave

No yet. But here is a patch.
