The Field object represents a field of GDB table or external database table (Table object), a field of query (Query object) and a field of the current record in a recordset (Recordset object). Possibility to get or set properties of the field depends on whether the field belongs to the Table::Fields, Query::Fields, Recordset::Fields, ForeignKey::Fields, PrimaryKey::Fields and TableIndex::Fields collections. The "Collection membership dependence" table determines possibility to execute methods or get/set properties of the field depending on the field membership in the collections.
