Question

有没有人知道一个好的脚本来获取SQL Server 2005的所有非聚集索引？

Answer 1

对于特定数据库中的所有非聚簇索引：

select object_name(object_id) as tablename, * 
from sys.indexes where type_desc = 'NONCLUSTERED'

这将返回系统表和非系统表。可替换地：

select t.name as tablename, i.* 
from sys.indexes i, sys.tables t
where i.object_id = t.object_id
  and i.type_desc = 'NONCLUSTERED'

仅用于用户土地非聚集索引。

Answer 2

您可以使用

获取表格的所有索引

exec sp_helpindex 'tablename'

您可以将其插入表中，并删除INDEX_DESCRIPTION以“CLUSTERED”开头的所有行

这是数据库中所有索引的脚本
