I'm too tired to find the words, so cut and pasted from answers.com: - "Indivisible. An atomic operation, or atomicity, implies an operation that must be performed entirely or not at all. For example, if machine failure prevents a transaction to be processed to completion, the system will be rolled back to the start of the transaction." Like Michael, I had understood that ZSQL database transactions were tied into Zope transactions, and would fail or succeed as a whole. Like him, I have found that - at least with this combination of DA & RDBMS - this is not so. I work around it, as I always do when a Microsoft product is involved. If I hit the same thing with PostgreSQL, I'll look into it deeper... -- Regards, PhilK Email: [EMAIL PROTECTED] PGP Public key: http://www.xfr.co.uk Voicemail & Facsimile: 07092 070518 “The creative impulse animates whatever instrument is placed at its disposal.” — Robert Fripp _______________________________________________ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
