Respuesta :
In microsoft access, when you have the field name firstname display as first name, you are changing caption property of the field as If you don't specify a caption for a table field, the field's FieldName property setting will be used as the caption of a label attached to a control or as the column heading in Datasheet view.
Caption property in MIcrosoft Access:
A string expression that can hold up to 2,048 characters is the Caption property.
A table field's FieldName property setting will be used as the caption of a label attached to a control or as the column heading in Datasheet view if you don't specify a caption for the field. T
he caption for the underlying table field will be used if you don't specify one for a query field. A form, button, or label won't have a caption if you don't set one, so Microsoft Access will give it a name based on the object, like Form1.
The FieldName property setting for the field will be copied to the control's Name property box and will also appear in the label of the control created if you create a control by dragging a field from the field list without specifying a Caption property setting for the field.
When the HyperlinkAddress or HyperlinkSubAddress property is set for a label or command button control, the text of the Caption property serves as the hyperlink display text.
