Subject UDFs and computed fields
Author Roger Vellacott
If wrote a UDF containing a function WEEKNO to return week numbers from
dates. It works a treat. So I put in a load of new fields to my tables in
the form


This also works nicely in wisql and such. But wheni run my Delphi app,
using TIBOQuery linked to TDatasource and VCL Controls, everything is blank.
If I remove the computed fields, everything comes back again. Tables without
computed fields behave throughout as normal.

Any ideas why?
