Hi,
i have the following situation:
Classic master detail tables using TwwIBOQuery Components (Infopower
rulez here).
In the detail query i linked both using the dataset property.
the master primary key field is a ID field defined as numeric(14,0) as
well as the detail field.
When i link the queries using the datasource property of the detail and
try to open the detail or master i get an "Invalid variant Operation"
message/exception.
the master PK field is a TLargeint field in delphi as well as the client
FK field.
I checked the generated param of my query and tried different datatypes
it doesn't work out.
Any ideas (i cannot switch to T_IBxxx components because of Infopower).
Regards
