Hi, I am working on a web app that interfaces with Microsoft SQL Server from Ubuntu through SQL Relay. I will be getting data from multiple databases. The issue seems to be that either Zope or SQL Relay cannot handle the Decimal type if the value is a null. If I do a query like this: SELECT * from myDatabase I get the following: <error> Site Error An error was encountered while publishing this resource. InvalidOperation Sorry, a site error occurred. Traceback (innermost last): * Module ZPublisher.Publish, line 194, in publish_module_standard * Module Products.PlacelessTranslationService.PatchStringIO, line 34, in new_publish * Module ZPublisher.Publish, line 146, in publish * Module Zope2.App.startup, line 222, in zpublisher_exception_hook * Module ZPublisher.Publish, line 115, in publish * Module ZPublisher.mapply, line 88, in mapply * Module ZPublisher.Publish, line 41, in call_object * Module Shared.DC.ZRDB.Connection, line 115, in manage_test * Module Products.ZSQLRelayDA.db, line 86, in query * Module decimal, line 571, in __new__ * Module decimal, line 2267, in _raise_error InvalidOperation: (Also, the following error occurred while attempting to render the standard error message, please see the event log for full details: '@@plone') </error> If I change it to "SELECT empid, reg from myDatabase" it will work as long as reg is not a NULL. I can get it to work if I use "isnull" functions on all my decimal type fields, but I would like to avoid that. Is this a known issue with a workaround? I am using Zope 2.9.4-final on Ubuntu with SQL Relay 0.39.4. Mike Driscoll Applications Specialist MCIS - Technology Center
