hi Mauricio.
the assumption is that you are using the latest v0.9/dev.
if you are getting only "boolean-based blind" as the result of
detection phase then that's the only technique that can be used in
further steps.
but, if you are getting more of techniques, then they'll be used in
their speed order - 1) UNION, 2) ERROR, 3) BLIND, 4) TIMED, 5) STACKED
all techniques can be used for all enumerations
in case that you are not getting UNION technique as a result of the
detection phase then it would be good to use something like: --level=3
--risk=2 (more techniques and boundary prefixes/suffixes will be used)
in the default run there will be a test against a UNION based
injection up to 10 columns, but with higher level it will test more
(e.g. --level=2 --> 1-10 & 10-20; --level=3 --> 1-10 & 10-20 & 20-30).
in case that you know number of columns to be between 10 and 15 you
can use default settings and only put --union-cols=10-15
one more thing about information_schema database. assumption is that
the MySQL DBMS is > 4 and that there are no read restrictions on it.
