Penetration Testing: RE: sql injection with order by

Adding the '--' comments out everything after the sql you're putting in.  It
won't work without it because you are getting a syntax error on what you are
trying to run.

Subject: sql injection with order by



Hi all,
I am trying to make an injection with the statement below,

SQL = "SELECT ProID, CusID, Name FROM ProTur WHERE Lan=0 AND
CusID='%Customer%' ORDER BY Sira, ProjeTurID"

in the statement above I inject ")select @@version-- for the variable
Customer. But unless I have ended inject code with -- nothing happens.
I get
SQL = "SELECT ProID, CusID, Name FROM ProTur WHERE Lan=0 AND
FirmaID=")select @@version-- ORDER BY Sira, ProjeTurID"
what is the problem? can anybody tell me?
Is the problem occurs from the word ORDER BY?
Thanks
