I use Python 3.2.3 on GNU/Linux 64bits (openSUSE 12.2).
I have created an in-memory connection with the following code:
conn = sqlite3.connect(":memory:", detect_types=sqlite3.PARSE_DECLTYPES,
check_same_thread=False)
conn.row_factory = sqlite3.Row
Then I have filled the database, but when it comes to copy it via
conn.iterdump(), it crashed with the following message:
File "/usr/lib64/python3.2/sqlite3/dump.py", line 30, in _iterdump
for table_name, type, sql in sorted(schema_res.fetchall()):
TypeError: unorderable types: sqlite3.Row() < sqlite3.Row()
It seems that the error appears because of the use of "sorted()". In fact, if I
don't change conn.row_factory or if I use a custom class _Row implementing
__lt__ method (see below) this error does not appear.
class _Row(sqlite3.Row):
def __lt__(self, x):
return False
