有几个关于分区的问题

有几个关于分区的问题，希望大家帮忙了
1. 表已经存在，能否再应运分区方案呢，如果可以，这么用？
2. sqlserver里能否直接通过执行Select * into 表 from 表2时，也带上分区方案，如果能这样那是方便不过？

可以
1:刪除普通索引
2:刪除主健索引並轉為分區表
3：再恢復主健索引
4:恢復普通索引

use TEMPDB
go
create table t(ID int identity ,Num int not null constraint PK_T primary key(Num,ID))
create index IX_T_Num on T(Num)

go
create partition function F_Partition(int)
as range right for values(1,100,1000)
go
CREATE PARTITION SCHEME P_schema
as partition F_Partition ALL to ([PRIMARY])

go
drop index IX_T_Num on T
alter table T drop constraint PK_T with(Move to P_schema(Num))

alter table t alter column ID int not null

alter table T add constraint PK_T primary key (Num,ID)


select * from T


DROP TABLE T
DROP PARTITION SCHEME P_schema DROP partition function F_Partition

-----------------------------

如果主健只有一列時直接改

go
create table t(ID int identity constraint PK_T primary key,Num int not null )--只有一個ID
create index IX_T_Num on T(Num)

go
create partition function F_Partition(int)
as range right for values(1,100,1000)
go
CREATE PARTITION SCHEME  P_schema
as partition F_Partition  ALL to ([PRIMARY])

go
drop index IX_T_Num on T
alter table T drop constraint PK_T with(Move to P_schema(ID))--這里改為ID

alter table t alter column ID int  not null

alter table T add constraint PK_T primary key (ID)--改為ID


select * from T


DROP TABLE T
DROP  PARTITION SCHEME  P_schema
DROP partition function  F_Partition

-----------------------------------

如果是into生成的表，這樣用
