方法一：分步搬移(針對百萬數據量)
-----remove data----------
insert into BizOfferSearch_Insert_Temp
select top 2000000 id,0 isinsert
from BizOfferSearch a with(nolock) where ISPUBLISHED>=2 and ISPUBLISHED<>3
and tradingservicetype in(1,3,4) and id not like 'JS%'
select * into #temp11 from BizOfferSearch_Insert_Temp where 1=2
while (select count(0) from BizOfferSearch_Insert_Temp where isinsert=0)>1
begin
insert into #temp11
select top 400 * from BizOfferSearch_Insert_Temp where isinsert=0
insert into [192.168.1.61].offerhistorybybak.dbo.BizOfferSearch_APIDBDK_20100709_1
select * from BizOfferSearch a with(nolock) where ID in(select ID from #temp11)
update BizOfferSearch_Insert_Temp set isinsert=1 where id in (select id from #temp11)
truncate table #temp11
waitfor delay '00:00:00.500'
end
truncate table #temp11
drop table #temp11
truncate table BizOfferSearch_Insert_Temp
-----delete data-------------------
select id,0 isdelete into #temp1 from [192.168.1.61].offerhistorybybak.dbo.BizOfferSearch_APIDBDK_20100709_1 with(nolock)
select * into #temp11 from #temp1 where 1=2
while (select count(0) from #temp1 where isdelete=0)>1
begin
insert into #temp11
select top 400 * from #temp1 where isdelete=0
delete BizOfferSearch with(rowlock) where id in (select id from #temp11)
update #temp1 set isdelete=1 where id in (select id from #temp11)
truncate table #temp11
waitfor delay '00:00:00.500'
end
truncate table #temp11
drop table #temp11
truncate table #temp1
drop table #temp1
方法二：bcp(針對千萬以上的數據量)
如果數據量很大，通過分步搬移已經不能滿足要求，這時我們可以考慮用bcp
步驟：
1. 將原數據導入到文件（運行時去掉換行，一次w記錄）
bcp "select top 5000000 * from BKOffer.dbo.BizOfferSearch a with(nolock)
where ISPUBLISHED>=2 and ISPUBLISHED<>3 and tradingservicetype in(1,3,4)
and id not like 'JS%' "
queryout H:\Contacts1.txt -q -S"192.168.1.65" -c -T
2.將文件拷貝到備份機器
3.將文件中的數據導入到備份機器上的新表
bcp offerhistorybybak.dbo.BizOfferSearch_APIDBDK_20100709 in H:\Contacts1.txt -T -c -m 1000
4.刪掉原數據（BizOfferSearch_Insert_Temp表只存Id和標誌位isinsert，值爲0或1）
insert into BizOfferSearch_Insert_Temp
select id,0 from [192.168.1.61].offerhistorybybak.dbo.BizOfferSearch_APIDBDK_20100709 with(nolock)
select * into #temp11 from BizOfferSearch_Insert_Temp where 1=2
declare @rowcounts int
select @rowcounts=count(0)/1000 from BizOfferSearch_Insert_Temp where isinsert=0
while (@rowcounts)>=0
begin
insert into #temp11
select top 1000 * from BizOfferSearch_Insert_Temp where isinsert=0
delete BizOfferSearch with(rowlock) where id in (select id from #temp11)
update BizOfferSearch_Insert_Temp set isinsert=1 where id in (select id from #temp11)
truncate table #temp11
select @rowcounts=@rowcounts-1
waitfor delay '00:00:00.500'
end
truncate table #temp11
drop table #temp11
truncate table BizOfferSearch_Insert_Temp
