Yes and no. AFAIK, current implementation of StoredProcedures for Zope allows 
you only get OUT parameters back (with annoying caveats, such as 
OracleDateTime type are not supported etc.). E.g.:


Then, e.g. SP exist in ZODB as "foo", you should just pass empty string in 
this case:

outParameter = context.foo(in_parameter = "Joe", 
                           out_parameter = '')

To use both IN/OUT as usually normal parameters, you should (somehow) use 
binding array (espesially in case of overloaded procedures) or use another 
procedure call (refer to DCOracle2 documentation at 
http://www.zope.org/Members/matt). But both of them are not implemented in 
ZOracleDA, they only present in DCOracle2 adapter as is.

To solve this, you need to improve ZOracleDA by these stuff. ;-)
