SQL Server 2005でデータベース内のすべてのインデックスとそのデータ型を取得する方法は？

Question

インデックスのオンライン再構築を許可しないタイプのデータベースのインデックスがいくつか存在するため、メンテナンス作業が失敗します。私の業界ではオフラインは選択肢ではないので、特定のインデックスでインデックスを再構築する独自のT-SQLタスクを作成する必要があります。データベースは多数の表と索引があるため、システムにすべての索引とそのデータ型を問い合せる方法はありますか？

が

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;

Answer 1

これは、あなたのヒープのような「ベーステーブル」とクラスタ化インデックスの列と同様に、すべてのINCLUDE列を含むすべてのインデックスのすべての列が表示されますオンライン索引再構築（BLOB/XML/CLRタイプ）。 SQL Server 2012では、LOB列を使用したオンライン索引作成の制限が解除されたことに注意してください。Online Index Operations for indexes containing LOB columnsを参照してください。

最近、このような手順が行われました。それは、この目的（[これらのソリューションの両方が、私はここで言及]
