Sql server 如何在SQLServer2005中检索数据库中的所有索引及其数据类型？

我有一个维护任务失败了，因为数据库中有一些索引的类型不允许在线重建索引。脱机在我的行业中不是一个选项，因此我必须创建自己的T-SQL任务，在特定索引上重建索引。数据库很大，有很多表和索引，因此有没有办法查询系统中的所有索引及其数据类型？

这将显示所有索引的所有列，包括“基表”的列，如堆和聚集索引，以及所有包含列：

select o.name as [object_name],
    ix.name as [index_name],
    coalesce(c.name,cc.name) as [column_name],
    t.name as [type_name],
    coalesce(c.max_length, cc.max_length) as max_length
from sys.indexes ix
join sys.objects o
    on ix.object_id = o.object_id
left join sys.index_columns ic
    on ix.object_id = ic.object_id
    and ix.index_id = ix.index_id
    and ix.index_id > 1
left join sys.columns c
    on  ic.object_id = c.object_id
    and ic.column_id = c.column_id
left join sys.columns cc
    on ix.object_id = cc.object_id
    and ix.index_id in (1,0)
join sys.types t
    on t.system_type_id = coalesce(c.system_type_id,cc.system_type_id)  
where o.type = 'U'
order by object_name, index_name, column_name;

然后，您可以识别那些对联机索引重建不安全的BLOB/XML/CLR类型。请注意，在SQL server 2012中，取消了对使用LOB列构建在线索引的限制，请参阅。

我们最近制定了此类过程。为此，它具有HasBlobs标志

考虑到这点，这正是我想要的。非常感谢。
