OField

A field object represents a single column of data in a single record. OField objects are not independently opened; rather, you get them from an ODynaset. When navigation occurs on the dynaset, the OField object’s value changes to the value of the column in the new current record. OFields are convenient because they always reflect the value of the field in the current record. (In some cases, however, you may find it more straightforward to manipulate field values directly from the ODynaset using the GetFieldValue and SetFieldValue methods.) OField is a subclass of OOracleObject.

You can get OField objects from either an ODynaset or OFieldCollection object, using the GetField method.
