[Zope-DB] RE: selecting lobs from database

I'm running  Zope 2.7 with dcoracle2 and trying to select a lob from a
table via python script-zsql method and return it to a dtml document to
be displayed. This is my python script


compoundid = int(compoundid)

resultlist = []


for myrecords in container.select_lob(compoundid=compoundid):

    resultlist.append(myrecords.cdbregno)  #integer

    lob=myrecords['ctab']  #blob


    myclob=myrecords['molformula']  #clob



return resultlist


When I run this it displays the cdbrego but displays None for both lob
fields. Is this a data type manipulation issue or is it something
specific to dcoracle2 support for lobs?

The zsql method is a simple select statement select cdbregno, ctab,
molformula from compound_moltable where compound_id = <dtml-sqlvar
compoundid type=int>
