[sqlmap-users] SQLMAP Permission Denied on DUMP

[Mahdi H. <dig...@gm...>]

Hi There.
I'm trying to dump some data of a table from a target using sql map. but
i'm getting following error:

[00:04:07] [WARNING] the SQL query provided does not return any output
[00:04:07] [WARNING] something went wrong with full UNION technique (most
probably because of limitation on retrieved number of entries). Falling
back to partial UNION technique
[00:04:09] [WARNING] the SQL query provided does not return any output
[00:04:09] [WARNING] in case of continuous data retrieval problems you are
advised to try a switch '--no-cast' or switch '--hex'
[00:04:09] [WARNING] unable to retrieve the entries of columns 'x' for
table 'x' in database 'x' (permission denied)

I'm already using --hex
I got the error while i was using --start and --stop so there should be no
problem on the large size of the columns.

will be happy if you help me

thanks.
