I am trying to use UPDATE or insert after getting victim database information, for that I am using command:
sqlmap -u somewebsite.com/id=2 --sql-shell
> sql-shell : UPDATE username FROM ....
and I get an error everytime (also in other websites):
execution of custom SQL queries is only available when stacked queries are supported
And if I type
SELECT username FROM ...
I get correct results.
I've tried to google much about this, but no luck, if possible give me some advice to update victim's database. Thanks
