Well. If I do in right that way as you described it works for sure. But o=
nly if I=20
invoke it from the pure Python in my command line using Zope's=20
Python or other one, installed in my system. It works without problems.=20

But I'm asking about why this code below (simple stupid External Method, =
with id "sp" in a traceback below)=20
does not work -- see comments in a code (error cut&pasted below). Seems t=
hat SP.py=20
is not broken, since I event can't bound OracleDate type directly as in y=
our example above into
a procedure (a realy trouble probably deeper -- in DCOracle2.py or even i=
n dco2.so):

def insertDayReport(self, parent, odc):
    """ blah... """
    import DCOracle2 as dc

    # This get current Z Oracle DB Connection for current user   =20
    db =3D getattr(parent, odc)._v_database_connection.db
    cr =3D db.cursor()

    # If I call cr.procedure.pm.pm_08.insert_day_report.__doc__ -- it ret=
urns me
    # a corrent procedure description

    a =3D cr.procedure.pm.pm_08.insert_day_report(P_DT =3D dc.Date(2003, =
2, 10), # <-- CRASH HERE
                                                P_ACL_ID =3D 844L,
                                                P_DESCRIPTION =3D 'Descr'=
,
                                                P_SPENT_DAYS  =3D 1,
                                                P_DONE_PRC    =3D 10,
                                                P_COMMENT     =3D 'Commen=
t',
                                                P_ERR_MSG     =3D '')
    # Stupid output
    return '<pre>%s</pre>' % a


Returns me error:

To repeat again how look my Oracle Stored procedure:

function PM.PM_08.INSERT_DAY_REPORT returns OUT NUMBER, has arguments:
        P_DT IN DATE
        P_ACL_ID IN NUMBER
        P_DESCRIPTION IN VARCHAR2
        P_SPENT_DAYS IN NUMBER
        P_DONE_PRC IN NUMBER
        P_COMMENT IN VARCHAR2
        P_ERR_MSG IN OUT VARCHAR2
