得到SQL Server表名和欄位資訊

---表欄位名--

select b.[name] as '列名',c.[name] as '資料類型',b.length as '長度',d.value as '描述' from sysobjects a
left join syscolumns b on a.[id]=b.[id]
left join systypes c on b.xtype=c.xtype and b.xusertype=c.xusertype
left join sysproperties d on b.[id]=d.[id] and b.[colid]=d.[smallid]
where a.xtype='U' and a.type='U' and a.[name]='你的表名'

---所有表欄位名資訊--
SELECT

       (case when a.colorder=1 then d.name else '' end)表名,

       a.colorder 欄位序號,

       a.name 欄位名,

       (case when COLUMNPROPERTY( a.id,a.name,'IsIdentity')=1 then '√'else '' end) 標識,

       (case when (SELECT count(*)

       FROM sysobjects

       WHERE (name in

                 (SELECT name

                FROM sysindexes

                WHERE (id = a.id) AND (indid in

                          (SELECT indid

                                  WHERE (id = a.id) AND (name = a.name))))))) AND

              (xtype = 'PK'))>0 then '√' else '' end) 主鍵,

       b.name 類型,

       a.length 佔用位元組數,

       COLUMNPROPERTY(a.id,a.name,'PRECISION') as 長度,

       isnull(COLUMNPROPERTY(a.id,a.name,'Scale'),0) as 小數位元,

       (case when a.isnullable=1 then '√'else '' end) 允許空,

       isnull(e.text,'') 預設值,

       isnull(g.[value],'') AS 欄位說明
