SQLBulkCopy 성능 통계

다음 C# 코드에서는 SqlBulkCopy를 사용하여 빅데이터 양의 업로드를 수행할 수 있습니다.

    public void SaveDataTable(string connectionString, String tableName, int batchSize, DataTable table)
    {
        using (SqlConnection sqlConnection = new SqlConnection(connectionString))
        {
            sqlConnection.Open();
            var sqlTransaction = sqlConnection.BeginTransaction();
            try
            {
                //  SqlBulkCopyOptions ExternalTrasaction                    。
                using (SqlBulkCopy sqlBulkCopy = new SqlBulkCopy(sqlConnection, SqlBulkCopyOptions.TableLock, sqlTransaction))
                {
                    sqlBulkCopy.BatchSize = batchSize;
                    sqlBulkCopy.BulkCopyTimeout = 900;
                    sqlBulkCopy.DestinationTableName = tableName;
                    sqlBulkCopy.WriteToServer(table);
                    sqlTransaction.Commit();
                }
            }
            catch (Exception)
            {
                sqlTransaction.Rollback();
                throw;
            }
        }
    }
