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).

I'm not sure if this is the right place for this, if not, my apologies.
I've got a Clients table in an interbase db with various fields, one of which is a BLOB field (subtype text), used to maintain some notes.
When inserting a Client into the table, this field populates fine.
However, when attempting to update the client, for some reason, it
won't.
It
just will not allow me to do an update with the notes field in the statement. I've googled around, and found lots of bits helping with
Delphi,
and lots of statements that BLOB fields in Interbase are tricky to
update,
but nothing that helps.
Has anyone out there found a way around this?
I'm using currently using gvib as my database adaptor, as kinterbase
does
not seem to want to install at all (seemingly problems with ldap ..).
My Zope instance is installed from a Plone installer. Zope Version (Zope 2.6.1 (binary release, python 2.1, win32-x86), python 2.1.3, win32) Python Version 2.1.3 (#35, Apr 8 2002, 17:47:50) [MSC 32 bit

Hi Bob, Thanks again for your reply. I've tried this approach before, so I'm thinking perhaps its my db adaptor. Which one are you using, if you don't mind me asking? I've had trouble installing kinterbase (it complains about LDAP..?), so at the moment I use gvib. I've pencilled in quite a bit of time today to try to get kinterbase installed. Unfortunately I'm on Windows, which I'm guessing contributes to the installation problems! Thanks once again for your help and your time. If this doesn't work, I'll look for the Zope-DB list, and basically go and bother someone else. Cheers Ashley

Hi Phil, Thanks for your email. The LDAP error, as it turns out, was from "zkinterbasdb" or something like that - something I probably picked up thinking it was kinterbase. Forgive my ignorance, but what was your procedure for installing kinterbase? I've tried just installing kinterbasDA, which required kinterbasdb. So I've tried installing kinterbasdb (from an executable, rather than the more familiar simple compressed file), but I keep getting an ImportError: DLL load failed when looking at the product in Control_Panel/Products. The error refers to a line "import _kinterbasdb as _k". I've assumed that its referring to import _kinterbasdb.pyd, rather than a dll, as thats all that I can find. I've tried copying it into several places, but I'm assuming that its compiled by the exe at install time, and is specific to the folder its placed in. Or I could be completely wrong! Any hints as to your procedure would be appreciated, as this is getting frustrating (probably meaning I'm missing stupid things).

Aha - thought it was unlikely to be from the DA!

You want a .pyd, not a .dll - that bit's fine. I may have started from a different point from you - I have a Plone install with multiple Zope and Plone sites in it, and Plone does a couple of things differently. In a Plone install on Windows, the Plone's Python is set as the system's Python. This means that when you run the binary installer for kinterbasdb it installs in the right copy of Python. I wonder if you have Python installed elsewhere, and the binary installer is finding the wrong one? The other thing is the mxExtensions - do you have these installed?
Any hints as to your procedure would be appreciated, as this is getting frustrating (probably meaning I'm missing stupid things).
I didn't do anything beyond what the docs for the three packages (mx Extensions, Python db i/f, Zope DA) stated - but there is always the joy of working out what those instructions /really/ mean, as in "now I've done it, I understand it! I do remember some frustration, but I think it was just the system Python thing. If the above doesn't help, the traceback from your error should be our starting point - stick with it, because since installing it I haven't even needed to think about this DA except when I've upgraded it, it just works (for me - YMMV and all that)! -- Regards, PhilK Email: phil@xfr.co.uk PGP Public key: http://www.xfr.co.uk Voicemail & Facsimile: 07092 070518 "You'll find that one part's sweet and one part's tart: say where the sweetness and the sourness start." - Tony Harrison
Hi Phil & Ashley, I also have kinterbasedbDA working on Windows. It is with an older version of Zope (2.6.4). The DA version is 1.1.1.1. The kinterbasdb version is 3.0.1. It uses a dll called _kinterbasedb.dll, instead of a .pyd. I don't remember the exact installation process anymore, but I think I just grabbed it from another working site. If you like, I could zip it up and send it to you. The site uses blobs (all sub_type text) in many places, so maybe older/other versions don't support this as well. Bob Corriher CTO P-Wave Inc.

Hi Bob, If you don't mind doing that, I'd really appreciate it. Nothing I seem to be trying to install at the moment seems to be working. As with Phil, mine is from a Plone install, but I have got other versions of Python elsewhere, (I think there's even an old Zope standalone instance still lurking somewhere, altho I don't think it can run) just to confuse matters. Anyway, my Zope is even older - 2.6.1, so hopefully it'll be compatible. Thanks very much again for your help.

Hi Bob, Thanks for your reply. Sorry if I've replied to this twice, but I thought I replied ages ago, and it hasn't appeared yet. If at first you don't succeed ... I've tried this approach, but with no luck. Which db adaptor do you use? I've been using gvib, as I don't seem to be able to install kinterbase properly, I'm hoping to change that today, with a bit of luck.
