problem with select field in a form

I have e problem when i want to see some data in a form.
I explain that:
I insert data in a form using a select field with tha automatic metod (with sql). If i open the form (in update mode) with that data (in readonly mode) and the sql results are changed, i don’t see that.
Can i open form (in update mode and readonly data) and see the data if in the select there isn’t the same result?

I hope i have been clear.


No, I think wasn’t clear. screenshots can help

if i’m in edit mode and the field is in readonly mode, i want to see the data stored in the field even though it’s not among results on the query of the select field.
