### Feature10： Big data insert or update
```cs
//Insert A million only takes a few seconds
db.Fastest<RealmAuctionDatum>().BulkCopy(GetList());
1.1 BulkCopy
db.Fastest<Order>().BulkCopy(lstData);//insert
db.Fastest<Order>().PageSize(100000).BulkCopy(insertObjs);
db.Fastest<System.Data.DataTable>().AS("order").BulkCopy(dataTable);
1.2 BulkUpdate
db.Fastest<Order>().BulkUpdate(GetList())//update
db.Fastest<Order>().PageSize(100000).BulkUpdate(GetList())
db.Fastest<Order>().BulkUpdate(GetList(),new string[] { "Id"});//no primary key
db.Fastest<Order>().BulkUpdate(GetList(), new string[]{"id"},
new string[]{"name","time"})//Set the updated column
//DataTable
db.Fastest<System.Data.DataTable>().AS("Order").BulkUpdate(dataTable,"Id");//Id is primary key
db.Fastest<System.Data.DataTable>().AS("Order").BulkUpdate(dataTable,"Id",Set the updated column);
1.3 BulkMerge （5.1.4.109）
db.Fastest<Order>().BulkMerge(List);
db.Fastest<Order>().PageSize(100000).BulkMerge(List);
//update A million only takes a few seconds
db.Fastest<RealmAuctionDatum>().BulkUpdate(GetList());//A million only takes a few seconds完
db.Fastest<RealmAuctionDatum>().BulkUpdate(GetList(),new string[]{"id"},new string[]{"name","time"})//no primary key
//if exists update, else insert
var x= db.Storageable<Order>(data).ToStorage();
x.BulkCopy();
x.BulkUpdate();
//set table name
1.4 BulkQuery
db.Queryable<Order>().ToList();//Slightly faster than Dapper
//Suitable for big data export
List<Order> order = new List<Order>();
db.Queryable<Order>().ForEach(it=> { order.Add(it); } ,2000);
1.5 BulkDelete
db.Deleteable<Order>(list).PageSize(1000).ExecuteCommand();
db.Fastest<RealmAuctionDatum>().AS("tableName").BulkCopy(GetList())
//set page
