Reading Oracle BLOBS from Zope
|
|
I want to read an Oracle BLOB and display it. I have seen several
examples on the internet, but none of them seem to work.
I am on the following platform:
Zope Version (Zope 2.6.1 (source release, python 2.1, linux2), python
2.1.3, linux2) Python Version 2.1.3 (#1, Sep 19 2002, 21:42:04) [GCC
2.96 20000731 (Red Hat Linux 7.3 2.96-110)] System Platform linux2
I am trying to read a BLOB from an Oracle database. I have noticed
that when I test the ZSQL, I get the following error:
The SQL:
select wgtphot_photo as photo from kenglund.wgtphot where wgtphot_pidm
= 252853
This seems to be returning the image ok. I had to set the max results
to one to get it to work.
The Python:
result = []
lob = ['image']
for row in context.sqllogo:
lob = row['photo']
# result.append({'image': lob.read()})
# above was remmed
container.REQUEST.RESPONSE.setHeader('content-type', 'image/jpeg') return lob
The Web page:
<td><img src="logo;" alt="foto"></td>
Can you give me some ideas as to what I am doing wrong, or if it is
even possible to do what I am trying? I know we are on an old version
of Zope and Python. I inherited this system from someone no longer
working here, and upgrading is on my to-do list.
Thanks so very much!
