Deary me. Did you actually test out that bit of code before you posted it?
No, I thought not. I even gave you a test harness to make it easy for you
to check the quality of your code before posting.
All you had to do was to add another test:
def test_escapebackslashwild2(self):
self.cursor.execute(
("select name from pythontest where name like %s" %
SQLString("%" + EscapeSQLWild(r"\%") + "%")))
expected = (('x\\%x',),)
self.assertEqual(expected, self.cursor.fetchall())
and the output is:
======================================================================
FAIL: test_escapebackslashwild2 (__main__.Tests)
----------------------------------------------------------------------
Traceback (most recent call last):
File "mysqltest.py", line 111, in test_escapebackslashwild2
self.assertEqual(expected, self.cursor.fetchall())
AssertionError: (('x\\%x',),) != (('x\\nx',), ('x\\%x',))
----------------------------------------------------------------------
as I said before, your escaping is too late and not enough. You've got a
search for a literal backslash in there sure enough, but you haven't
managed to escape the percent character.
Try again.
