Penting

Beberapa informasi terkait produk prarilis yang dapat diubah secara signifikan sebelum dirilis. Microsoft tidak memberikan jaminan, tersirat maupun tersurat, sehubungan dengan informasi yang diberikan di sini.

Mendapatkan atau mengatur Boolean yang menunjukkan apakah Anda ingin menerapkan batasan pemeriksaan tabel dan kolom.

public:
 property bool CheckConstraints { bool get(); void set(bool value); };

public bool CheckConstraints { get; set; }

member this.CheckConstraints : bool with get, set

Public Property CheckConstraints As Boolean

Nilai Properti

Boolean

true untuk memberlakukan batasan pemeriksaan; false untuk mengabaikan batasan pemeriksaan selama operasi impor massal.

Penerapan

CheckConstraints

Contoh

Contoh berikut membuat BulkInsertTask, lalu memperlihatkan pengaturan default properti, termasuk CheckConstraints, dengan menggunakan TaskHost. Contohnya kemudian mengatur dua bidang, untuk menunjukkan cara mengatur nilai bidang.
