Need help to execute requests with the "--where" option

[turboman99maker]

Is your feature request related to a problem? Please describe.
I would like to know if sqlmap is able to search an exact number of characters on a column.
Example : in the column | FILE_NAME | varchar(255) |

-D database -T documents -C FILE_NAME --dump --where "FILE_NAME=(64 CAR)"
(in the case of an exact 64 characters search)

-D database -T documents -C FILE_NAME --dump --where "FILE_NAME<(12 CAR)"
(in the case of a less than 12 characters search)

Another thing : I would like to know the weight of a database. If is possible with sqlmap to know that criteria before launching a dump ?

Thanks

i am not sure if i got you right (NOTE: you haven't told the DBMS type - so I guess it is MySQL/MariaDB), but maybe you are searching for:

--where "CHAR_LENGTH(FILE_NAME)=64"

example:

python sqlmap.py -u "http://testphp.vulnweb.com/artists.php?artist=1" --dump -T artists -D acuart --where "CHAR_LENGTH(aname)=5" --fresh-queries

nope. nobody ever asked for this, thus, i would guess that it would not be used option at all
