SQL Server 2005 的分区表(partition table)是复杂的,特别是对于初学者来说。不管怎样,我们还是掌握了分区函数(partition function),分区方案(partition scheme),最后终于创建了一个分区表出来。但之后呢,或许你想查看分区表的各个分区分区列的取值范围(这个分区的理论最小值和最大值),虽然可以通过分区函数中定义的边...

在这个时候,除了你可以优化索引及查询外,你还可以做什么?建立分区表(Table Partition)可以在某些场合下提高数据库的性能,在SQL Server 2005中也可以通过SQL语句来创建表分区,但在SQL Server 2008中提供了向导形式来创建分区表。本文介绍了如何来创建分区表。
By treating partitioned tables as indexes, SQL Server 2008 can frequently use much simpler query plans. Let's look at the SQL Server 2008 plan for the above example:|--Table Scan(OBJECT:([T]))This query plan is no different than what you might see if you scanned any other ordinary ...
