Hi Ashely,
I use Interbase (and Firebird) in Zope regularly and I just use the
regular ZSQL Method syntax for blob fields:
<dtml-sqlvar name="blob_fld" type="nb">
to update the field.If the field may be left null, I usually use
something like this in the ZSQL Method:
<dtml-if blob_fld>
<dtml-sqlvar name="blob_fld" type="nb">
<dtml-else>
null
</dtml-if>
Apply commas at the end (or beginning) of the <dtml-sqlvar> and null if
necessary.
This should work for Interbase from version 4.x thru Interbase 6.x and
for all versions of Firebird.
If you need further help, just email me (and the list). Also, there is a
Zope-DB list for discussing Zope and RDBMS issues and the real gurus
hang out there.

Hi bobb, thanks for your reply.
If I found the right post (reading an image from blob in mysql and
displaying it), then thanks very much but I don't think it'll apply too much
to my situation. I can retrieve the contents of the blob field fine, its
updating it that causes the problems.
Thanks again, though.
I posted directly out of Outlook Express, by the way, just hitting "New
Post".
Kind regards
Ashley

Also, your post came through as a newsgroup posting, which means I had to
cut / paste / finagle the whole thing to reply... It's the first time I've
ever seen that (I use m$ outlook express) How are you posting to here?
(curious, that's all)
