I have a stored procedure that has a single output parameter. Why do I
have to pass it a string big enough to hold the value it is to receive?
Why can't I pass an empty string or None?
>>> import cx_Oracle as oracle
>>> connection = oracle.connect('usr/[EMAIL PROTECTED]')
>>> cursor = connection.cursor()
>>> network_name, = cursor.callproc('my_pkg.get_network_name_sp', ('',))
Traceback (most recent call last):
File "<interactive input>", line 1, in ?
DatabaseError: ORA-06502: PL/SQL: numeric or value error: character
string buffer too small
ORA-06512: at "USR.MY_PKG", line 35
ORA-06512: at line 1
The following works fine, but I don't like having to do it:
>>> network_name, = cursor.callproc('my_pkg.get_network_name_sp', (' ' * 32,))
Am I missing something obvious here?
