The following example shows the buggy implementation. The same example works fine with sqlite and postgresql.
cursor = connection.cursor()
cursor.execute('create table test (Field1 NUMBER(11),Field2 NUMBER(11))')
cursor.executemany('insert into test values (%s, %s)', [(i,i+1) for i in range(1,100)])
It returns the following error message:
File "C:\packages\Python-2.5\lib\site-packages\django\db\backends\util.py", line 30, in executemany
return self.cursor.executemany(sql, param_list)
File "C:\packages\Python-2.5\lib\site-packages\django\db\backends\oracle\base.py", line 125, in executemany
query, params = self._rewrite_args(query, params)
File "C:\packages\Python-2.5\lib\site-packages\django\db\backends\oracle\base.py", line 101, in _rewrite_args
query = smart_str(query, self.charset) % tuple(args)
