將SQL SERVER中所有表或某一個表的列資訊顯示出來

    正在作一個關於SQL SERVER資料庫的程式，要讀取資料庫中的列的資訊，從網上找了很多資料，終於找出來比較理想的sql語句，執行後返回的列分別是：表名、列名、列類型、列長度、列描述、是否主鍵，語句如下：

（如果只想操作一個表的，那麼把最後的％換成表名就可以了。）

SQLServer2000下能用：

 

SELECT SysObjects.Name as tb_name, SysColumns.Name as col_name, SysTypes.Name as col_type, SysColumns.Length as col_len, isnull(SysProperties.Value,SysColumns.Name) as col_memo,
case when SysColumns.name in
(select primarykey=a.name
FROM syscolumns a
 inner join sysobjects b on a.id=b.id  and b.xtype='U' and b.name<>'dtproperties'
 where  exists(SELECT 1 FROM sysobjects where xtype='PK' and name in (
 SELECT name FROM sysindexes WHERE indid in(
  SELECT indid FROM sysindexkeys WHERE id = a.id AND colid=a.colid
 )))
and b.name=SysObjects.Name
)
 then 1 else 0 end as is_key
 FROM SysObjects,SysTypes,SysColumns
LEFT JOIN SysProperties ON (Syscolumns.Id = Sysproperties.Id AND
 Syscolumns.Colid = Sysproperties.Smallid)
 WHERE (Sysobjects.Xtype ='u' OR Sysobjects.Xtype ='v')
AND Sysobjects.Id = Syscolumns.Id AND SysTypes.XType = Syscolumns.XType
AND SysTypes.Name <> 'sysname' AND Sysobjects.Name Like '%' ORDER By SysObjects.Name, SysColumns.colid

SQLServer2005下能用：

  SELECT sysobjects.Name as tb_name, syscolumns.Name as col_name, SysTypes.Name as col_type, syscolumns.Length as col_len, isnull(sys.extended_properties.Value,syscolumns.Name) as col_memo,
case when syscolumns.name in
(select primarykey=a.name
FROM syscolumns a
 inner join sysobjects b on a.id=b.id  and b.xtype='U' and b.name<>'dtproperties'
 where  exists(SELECT 1 FROM sysobjects where xtype='PK' and name in (
 SELECT name FROM sysindexes WHERE indid in(
  SELECT indid FROM sysindexkeys WHERE id = a.id AND colid=a.colid
 )))
and b.name=sysobjects.Name
)
 then 1 else 0 end as is_key
 FROM sysobjects,SysTypes,syscolumns
LEFT JOIN sys.extended_properties ON (Syscolumns.Id = sys.extended_properties.major_id AND
 Syscolumns.Colid = sys.extended_properties.minor_id)
 WHERE (sysobjects.Xtype ='u' OR Sysobjects.Xtype ='v')
AND Sysobjects.Id = Syscolumns.Id AND SysTypes.XType = Syscolumns.XType
AND SysTypes.Name <> 'sysname' AND Sysobjects.Name Like '%' ORDER By SysObjects.Name, SysColumns.colid
