[sqlmap-users] error or bug

[Jonatah R. <jon...@ho...>]

Hello guys, i made 3 attempts injection, all 3 have unequal information, one said there was no injection, the other said through heuristics to be Firebird DBMS, and the DBMS be another SAP MaxDB. I also tested it with --tamper, and --string, as stated sqlmap, stated that it was a false positive. It would be a bug or error?
Love information, more and more, I'm hungry :-).
