Question

我在Microsoft SQL Server 2008 R2中有一个表，它有100,000条记录。

我需要将它拆分为10个表，每个表有10k个记录。我不想对表进行分区，而是将其完全拆分为10个不同的表。这可能吗？

Answer 1

你可以使用NTile

;with cte
as
(
select ntile(10) over (order by somepk column) as somecol
,* from table 
)
select * from cte where n=1--change n value to get each partition

Answer 2

SELECT * 
 INTO new_tb1 
 FROM old_tb
 WHERE row >= 1 AND row<= 10000;

SELECT * 
 INTO new_tb2 
 FROM old_tb
 WHERE row>= 10001 AND row<= 20000;

 INTO new_tb3 
 FROM old_tb
 WHERE row>= 90001 AND row<= 100000;
