Ok.
But, then maybe we should give the user (I mean the developper using 
Simpleorm) an access to the Clob object, instead of fetching its value 
on queryFieldValue ?
And maybe add a custom method to SFieldClob that would effectively fetch 
the value, but not on queryFieldValue ?


Another point is, did this code work ? I'm asking because the break 
condition in queryFieldValue seems erroneous, as reader.read(buf) will 
return -1 on end of file, not 0. ?

                I've been looking at your code, and I was wondering why
                Clobs wouldn't be comparable... What is the reason
                behind that ?<br>
                Typically, Postgresql type for Clobs (TEXT) would just
                compare fine, as well as java representation of a Clob
                (a String).<br>
                Is there any Oracle specificity around that, or simply a
