Re: [cx-oracle-users] How to use user-defined data-types?

[Anthony T. <an...@co...>]

Currently, user defined types are not supported with cx_Oracle. You have 
to use scalar types and anonymous PL/SQL blocks or call procedures and 
functions to do the work. I do intend to do something about supporting 
user defined types but it will be some time before I will have anything 
useful -- I'm way too busy right now with my own work to deal with 
things that I don't actually use myself. :-(
