Reply-To: I have installed DCOracle 1.3 under Solaris 2.7, Python 1.5.2 and Oracle 8i. I have a testing table: docnum char(20) lang char(2) fulltext nclob I am trying to insert some unicode strings into the database. I have converted them using DCOracle.dbi.dbiRaw(). The insertion fails with the following error: Traceback (innermost last): File "test.py", line 41, in ? curs.execute(com,x=docnum,y=lang,z=raw) File "DCOracle/DCOracle/ociCurs.py", line 271, in execute r = self._execute(params__, kw) File "DCOracle/DCOracle/ociCurs.py", line 232, in _execute if rc!=3129: self._error() File "DCOracle/DCOracle/ociCurs.py", line 83, in _error raise error, (rc, oci_.OracleErrorMessage(self._c.lda, rc)) oci.error: (12704, 'ORA-12704: character set mismatch\012') I could not find out yet if it's a DCOracle related problem (in combination with Oracle 8i) or if it is a configuration problem of my environment. Thanks for any hint or idea, Andreas
