[sqlmap-users] SQLMAP bug

[Jerzy Y. K. <JY...@65...>]

Hi Guys,

Great tool but for the first time ever I've managed to see the following
error when testing oracle DB:

sqlmap version: 1.0-dev-74552be
Python version: 2.6.6

param --sql-query=SELECT UTL_INADDR.get_host_name FROM dual;
Technique: TIME
