Hi

When in a table a field is defined as integer (number(1,0)) --> the persistent queryfield has the type: TIntegerField.
But if I create a view including a union, delphi or ODAC recognize the same field as TFloatField. Therefore I get error messages in my forms, because the same form use both, one time the TABLE and an other time the VIEW. But i need the persistent fields.

Does anyone have a solution for this problem?

Regards
Robert
