[SQL Server 2005] SQL Serverでテーブル定義取得

SQL Server 2005で、テーブル定義らしいものを取得するクエリです。
これを使って、テーブル定義書を自動生成させてます。

select
Col.name as '名称'
,(Select top 1 name From systypes Where systypes.xtype = Col.xtype) as '型'
,Col.length as '桁数'
,case isnull(Col.scale,0)
 when 0 then ' '
 else cast( Col.scale as char(10) )
 end '小数部'
,case  Col.isnullable
 when 0 then '○'
 else ' '
 end 'NN'
,isnull((select case colid when 0 then '' else '○' end  from sysindexkeys as keys where col.id = keys.id  and col.colid = keys.colid and keys.indid = 1),' ') as 'PK'
,isnull((select top 1 ex.value from sys.extended_properties as ex where col.id = ex.major_id and ex.minor_id = col.colid and ex.name = 'MS_Description' ),' ') as 'コメント'
From syscolumns as col
inner join sysobjects as obj on col.id = obj.id
Where obj.name = '<テーブル名>'
