More to the point as to what I am attempting to do: What I have done with Paradox and do not know how to duplicate with Zope is to place three editable fields on a form (Date, Person and Account) and a table that lists the store inventory. The store inventory is downloaded from Postgres each time the form is accessed, and is sorted (type, item). This info is displayed on the table as well as the item store number which is hidden from view or rather is in the underlying table. On the table is also an editable field to enter the quantity of goods issued. Paradox makes it a simple matter to filter the displayed info by type, or to search for the required item to locate it and enter the issued goods. The great benefit of using Zope is of course the access levels that can be set up. The site is to cover Safety, Quality and the store. The organisations owner/manager can from a browser, access the information he wants. Supplying him and others with the information from Zope, is of course relatively straight forward - it is the input forms that have me. Once I have got this one going the rest should be straight forward. As both Paradox and Python have a common root in Pascal I have not found too much difficulty in writing code in either. Some help will be much appreciated regards Max On Monday 01 October 2007 06:03, Andreas Jung wrote:

Huh? You can of course as much SQL statements within one Zodb request as you like. Why should this be limited to only one update??
I have not worked out how to enter multiple transaction yet.
There is usually no need to deal with transactions on your own. Most database adapters abort/commit together with a ZODB abort/commit. The transactional integrity is given.
It is probably pushing the boundary of Zope,
Unlikely your pushing the boundary...obviously you need a deeper understanding of Zope....at least your posting does not contain much valuable informations about what you are really trying to achieve and how you are trying it to achieve...another try...explain what you're trying to do and how.
