เนื่องจากฉันไม่คิดว่าหลามจัดการกับชนิดย่อยฉันจึงโพสต์รหัส c # นี้ที่ควร ฉันทดสอบด้วย Geodb น้ำ / ตัวอย่างน้ำเสียของ Esri และพบโดเมนที่ไม่ได้ใช้ต่อไปนี้:
HistoryType is not used
PLSSFirstDivisionType is not used
PLSSDirection is not used
PLSSPrincipalMeridian is not used
ParcelType is not used
PLSSSpecialSurveyType is not used
CartoLineType is not used
PLSSSecondDivisionType is not used
บ่อยครั้งที่ DBA รู้สึกรำคาญว่าโดเมนซึ่งเป็นตารางการค้นหาเป็นหลัก - ไม่สามารถเข้าถึงได้ผ่านทาง SQL
รหัสนี้ทดสอบจาก arcmap ( อัพเดทต่อความคิดเห็นของ Matt):
