Returns whether a field's DataSourceField:Field exists in the database.
Field.Exists
Read-only at run time. Not available at design time. Type: Boolean. Property applies to Field object.
This property indicates if the field is ignored, and excluded from the recordset.
It is only relevant in data source mode (DataMode = 0 – DataSource), and is read-only, intended solely for information purposes.
For a data field, Exists = False means that the field’s DataSourceField property contains a name that does not correspond to any field in the data source. Such fields are ignored, excluded from the Recordset. In all other cases, Exists = True.
