Hi,
I tried to solve problem my own way.
I tried to encapsulate binary data in dNoEscQuoteStr object, although
noticed two problems:
- first, we need to modify dNoEscQuoteStr class to accept buffer type
object, e.g.:
def __str__(self):
if not isinstance(self._value, str):
ret = array.array("c", self._value).tostring()
else:
ret = self._value
return ret
- second, we need to correct sql expression formatting in
dCursorMixin.__saverow() method
to avoid UnicodeDecodeError exception.
