我想知道在数据库中列出所有表的所有索引的最简单方法是。
我应该为每个表调用sp_helpindex并将结果存储在临时表中，还是有更简单的方法？
任何人都可以解释为什么约束存储在sysobjects中，但索引不是？
解决方法
以下是您需要的查询类型的示例：
select
i.name as IndexName,o.name as TableName,ic.key_ordinal as ColumnOrder,ic.is_included_column as IsIncluded,co.[name] as ColumnName
from sys.indexes i
join sys.objects o on i.object_id = o.object_id
join sys.index_columns ic on ic.object_id = i.object_id
and ic.index_id = i.index_id
join sys.columns co on co.object_id = i.object_id
and co.column_id = ic.column_id
where i.[type] = 2
and i.is_unique = 0
and i.is_primary_key = 0
and o.[type] = 'U'
--and ic.is_included_column = 0
order by o.[name],i.[name],ic.is_included_column,ic.key_ordinal
;
这一点对某个目的有些具体(我在一个C#应用程序中使用它来找到重复的索引并格式化输出，因此它实际上是可读的)。但是你可以很容易地适应你的需要。
