I’m setting up an ADO-based client dataset, and when I try to insert a null value into a TIntegerField, on Post I get Project raised exception class EDatabaseError with message 'Non-nullable column cannot be updated to Null'.
I know I’ve seen a way to set a TField as nullable before, but I can’t remember where or how. Does anyone know how to fix this?
EDIT: The field is set to Required = false at design time, and I’ve verified that it’s still false at runtime, but I still get the error.
Have you verified if the db field which this field represents
have a not null constraint?
