功能说明:将普通表转换成分区表 .

介绍:    在以上代码中，我们可以看出，这个表拥有一般普通表的特性——有主键，同时这个主键还是聚集索引。
         前面说过，分区表是以某个字段为分区条件，所以，除了这个字段以外的其他字段，是不能创建聚集
         索引的。因此，要想将普通表转换成分区表，就必须要先删除聚集索引，然后再创建一个新的聚集索
         引，在该聚集索引中使用分区方案。

        可惜的是，在SQL Server中，如果一个字段既是主键又是聚集索引时，并不能仅仅删除聚集索引。因此，
        我们只能将整个主键删除，然后重新创建一个主键，只是在创建主键时，不将其设为聚集索引，如以下
        代码所示：
