Re: [Zope] RE: Blobs in Interbase
Hi Ashley, This error rings a bell with me. I can't remember where or what I did for sure, but I think I might have just forced a conversion to a string (with str()) before I updated the table It might have been with a unicode string. You could do this before you pass the parameter to the ZSQL Method. It might be worth a try. Bob Corriher CTO P-Wave Inc. Ashley Lloyd wrote: Hi Bob, thanks again!! When attempting to update the entity, I get the following error details: Error Type ProgrammingError Error Value (-413, 'execute.isc_dsql_execute: conversion error from string "BLOB".

The metatata of the table has the notes field definition as: EN_NOTES BLOB SUB_TYPE 1 SEGMENT SIZE 80, There is nothing else of any real interest in the table - an update that does not involve the notes works perfectly!

[Zope] Blobs in Interbase
Hi Ashely, I use Interbase (and Firebird) in Zope regularly and I just use the regular ZSQL Method syntax for blob fields: to update the field.If the field may be left null, I usually use something like this in the ZSQL Method: null Apply commas at the end (or beginning) of the 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. HTH Bob Corriher CTO P-Wave Inc. Ashley wrote: 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.

RE: [Zope] how to include Flash/SWF objects in Zope website?
Hi Fred, We use Flash in most of the sites we develop with Zope. We just upload the swf file into a File object and call it from the index_html method as follows: splashpage http://active.macromedia.com/flash2/cabs/swflash.cab#version=4,0,0,0" ID=splashpage WIDTH=550 HEIGHT=400> http://www.macromedia.com/shockwave/download/index.cgi?P1_Prod_Version=ShockwaveFlash"> The File object is named splaspage.swf, but the extension is not necessary. It could have been called splashpage or anything else. Hope this helps.
