Mengirim Data ke Kolom FILESTREAM Menggunakan IRowsetFastUpload SQL Server Native Client (OLE DB)
Berlaku untuk: SQL Server
Azure SQL Database
Azure SQL Managed Instance
Azure Synapse Analytics Analytics
Platform System (PDW)
Sampel ini menggunakan antarmuka IRowsetFastUpload untuk mengirim antara 4MB dan 4GB data ke kolom aliran file.
Untuk informasi selengkapnya tentang fitur aliran file, lihat Dukungan FILESTREAM (OLE DB).
Contoh
Sebelum Anda mengkompilasi dan menjalankan sampel ini, aktifkan dukungan FILESTREAM (Aktifkan dan KonfigurasiKAN FILESTREAM).
Pastikan variabel lingkungan INCLUDE Anda menyertakan direktori yang berisi sqlncli.h.
Server harus memiliki direktori yang disebut C:\DBFsa; di sinilah sampel akan membuat database. Instans SQL Server Anda harus memiliki akses tulis ke lokasi ini (misalnya, masuk sebagai akun sistem lokal).
Salin daftar kode pertama dan tempelkan ke dalam file bernama ISSHelper.h.
Salin daftar kode kedua dan tempelkan ke dalam file yang disebut ISSHelper.cpp.
Salin daftar kode ketiga dan tempelkan ke dalam file yang disebut IRowsetFastLoadUpload.cpp.
Kompilasi IRowsetFastLoadUpload.cpp, ISSHelper.cpp, ole32.lib, dan oleaut32.lib.
Saat menjalankan sampel ini, Anda harus meneruskan nama server, atau server\instance_name, serta nilai antara 4 MB (0x400001) dan 4 GB (0xFFFFFFFF) yang menunjukkan jumlah data yang akan ditulis.
Daftar kode keempat (Transact-SQL) menghapus database yang dibuat oleh sampel ini.
