⑵ 请问在数据库中对一个表创建了聚簇索引，应该怎么删除该聚簇索引，再重新建立聚簇索引呢

删除索引
drop clustered index 索引名
创建索引
create clustered index 索引名 on 表名

⑶ oracle 11G 簇在OEM如何建立

运行命令

⑷ 数据库中建立的聚簇索引是什么意思 谢谢指教

聚簇索引也叫簇类索引，是一种对磁盘上实际数据重新组织以按指定的一个或多个列的值排序。由于聚簇索引的索引页面指针指向数据页面，所以使用聚簇索引查找数据几乎总是比使用非聚簇索引快。每张表只能建一个聚簇索引，并且建聚簇索引需要至少相当该表120%的附加空间，以存放该表的副本和索引中间页。

⑸ 怎样在excel中建立簇状柱形图

最佳答案|||||||方法：1、打开EXCEL表格，选中数据区域，之后点击插入--图表--柱形图。2、点击“二维柱形图”---簇状柱形图。3、确定后，效果如下（自己可根据需要调整图表的样式及颜色）||||||本回答由电脑网络分类达人

⑹ word如何数据库数据创建一个簇状二维矩形图

方法一：你可以在Word中点插入—图表，但它也是依靠Excel完成的。
方法二：可以直接在Excel中做然后再剪切到Word里来至于要求三，可以在Excel里做出来的。

⑺ 建立索引聚簇的三个步骤分别是

1先在数据库中创建聚簇，并指出连接连个表的列的数据类型和大小。
2在该聚簇中创建索引。
3指定在聚簇中使用CREATE TABLE语句创建表！

⑻ sql 创建一个聚簇索引

在sql中，如果在创建表的时候创建了primary
key，没有为primary
key指定名称，数据库会自动的为你创建一个以‘pk’打头的约束名。创建主键后，还会自动生成一个“唯一聚集索引”。删除主键后，此索引同时也被删除。

⑼ 请问数据库中簇表和非簇表的定义是什么

聚集索引与非聚集索引
聚集索引是按物理顺序建立索引

⑽ 谁能分析一下SAP的数据库中为什么要用簇表

实际上，在编程时我们也不提倡从cluster table中取值，但我觉得，如果我们有时要从6、7个表 中抓取数值时，也会非常麻烦，就象BSEG，它由BSIS、BSAS、BSID、BSAD、BSIK、BSAK六个表的 总和，我们经常要从这六个表中取数，有BSEG会方便很多，这是我的个人感受。 还有个表叫GLT0，这个表的数据完全是计算出来的，但我们抓取数据时却很方便 您能告诉我：BSEG和BSIS、BSAS、BSID、BSAD、BSIK、BSAK六个表的关系怎样吗？
