SQL Injection - data ntext,image cannot group by....

[Sony Arianto Kurniawan <sony-ak () aritechdev com>]

Dear pen tester,
I'm interested in SQL injection. I try to know the table structure using ' 
having 1=1 --  and ' group by [table_name].[field_name]   to enumerate the 
fields.
But the table contains field with text or image type. I can't use group by 
and I can't continue the injection :( Is there any method to address this 
problem?
Thanks.
