以下資料,通過csdn的一位師兄從SQL版主那得到:
sql中
SELECT
(case when a.colorder=1 then d.name else '' end) N'表名',
a.colorder N'字段序號',
a.name N'字段名',
(case when COLUMNPROPERTY( a.id,a.name,'IsIdentity')=1 then '√'else '' end) N'標識',
(case when (SELECT count(*)
FROM sysobjects
WHERE (name in
(SELECT name
FROM sysindexes
WHERE (id = a.id) AND (indid in
(SELECT indid
FROM sysindexkeys
WHERE (id = a.id) AND (colid in
(SELECT colid
FROM syscolumns
WHERE (id = a.id) AND (name = a.name))))))) AND
(xtype = 'PK'))>0 then '√' else '' end) N'主鍵',
b.name N'類型',
a.length N'占用字節數',
COLUMNPROPERTY(a.id,a.name,'PRECISION') as N'長度',
isnull(COLUMNPROPERTY(a.id,a.name,'Scale'),0) as N'小數位數',
(case when a.isnullable=1 then '√'else '' end) N'允許空',
isnull(e.text,'') N'默認值',
isnull(g.[value],'') AS N'字段說明'
--into ##tx
FROM syscolumns a left join systypes b
on a.xtype=b.xusertype
inner join sysobjects d
on a.id=d.id and d.xtype='U' and d.name<>'dtproperties'
left join syscomments e
on a.cdefault=e.id
left join sysproperties g
on a.id=g.id AND a.colid = g.smallid
order by object_name(a.id),a.colorder
一個字,爽,還可以省去做DD時的好多麻煩.
如果不是很明白,可以將以上代碼放到SQL查詢分析器上運行一下就知道了(當然要打開一個數據庫啦)
