Help on SQL injection

Hi. I am testing an application on which the developer has implemented a code to prevent SQL injection. In his code he looks for a single quote in the input and adds another single quote.

However an input followed by this value %00' (inputvalue%00') on a search box generates an error message which looks like this:

Error [code]: 200 [Message]: SQL Error update tablename set ID1=123, ID2='text1', value='inputvalue''' where ID1=345
ORA-01756 - quoted string not properly terminated


How can I proceed further?

Thanks,
Rajesh

It seems, that %00 is working as commenting out the tail part of sql query.
But I don't have right now good ideas about how to close that single quoted string, which causes syntax error.
Anyway, you can suggest developer to handle null bytes with caution and filter them out or quote them before use.
