I saw this behaviour many times but I never solved it. Sometimes using sqlmap after retrieving good data from columns it fails retrieving only one of them. I can't figure out why this happens for just one of the columns.

This is an output sample:

| login       | pwdlogin                                         |
| TEST_USER   | ?\xa4\xd4\xc2??~?\xabccgq                        |
| TEST_USER   | ?\xc7\xd6\xc4???\x8f\xa4?\xa6\xaa\x9d\xb9?\xa5?b |
| TEST_USER   | ?\xc2\xe1\xae?\xa3\xa4?\xa9?t?k}?\xa3            |
| TEST_USER2  | ?\xc2\xda\xc2\xa0?\xa4`idknly?                   |
| TEST_USER3  | ?\xa2\xc1\xa6~y?u\xaa?\xa6                       |
| TEST_USER4  | ?\xa2\xb2\xb4??~?\xab`chj{?\xa5?                 |
| TEST_USER5  | ?\xa2\xb2\xb4??~?\xab`chj{?\xa5?                 |

What are the correct values for that column? – Slicedpan Aug 28 '13 at 15:26
@Slicedpan Should be a plain text password – Nucklear Aug 28 '13 at 15:32
Do the pws for TEST_USER4 and TEST_USER5 match? – Slicedpan Aug 28 '13 at 15:34
@Slicedpan Yes, it's a test database. If I try to retrieve the same user multiple times it gets the same string. – Nucklear Aug 28 '13 at 18:30
looks like an encoding problem? – schroeder Aug 30 '13 at 22:43

Try playing with character encoding options:

This is no "charset" problem. You are dumping the binary password hash. You should use --binary-fields=pwdlogin (hidden option).
