在項(xiàng)目開發(fā)過程中會(huì)用到數(shù)據(jù)字典,本文將詳細(xì)介紹mssql2005,2008如何導(dǎo)出數(shù)據(jù)字典，需要了解更多的朋友可以參考下
在你要導(dǎo)出數(shù)據(jù)字典的數(shù)據(jù)空中右鍵，新建查詢，執(zhí)行如下代碼即可
復(fù)制代碼 代碼如下:

SELECT
(case when a.colorder=1 then d.name else '' end)表名,d.xtype as 表類型,
a.colorder 字段序號(hào),
a.name 字段名,
(case when COLUMNPROPERTY( a.id,a.name,'IsIdentity')=1 then '√'else '' end) 標(biāo)識(shí),
(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) 主鍵,
b.name 類型,
a.length 占用字節(jié)數(shù),
COLUMNPROPERTY(a.id,a.name,'PRECISION') as 長度,
isnull(COLUMNPROPERTY(a.id,a.name,'Scale'),0) as 小數(shù)位數(shù),
(case when a.isnullable=1 then '√'else '' end) 允許空,
isnull(e.text,'') 默認(rèn)值,
isnull(g.[value],'') AS 字段說明
FROM syscolumns a left join systypes b
on a.xtype=b.xusertype
inner join sysobjects d
on a.id=d.id and d.xtype in ('U','V') and d.name<>'dtproperties'
left join syscomments e
on a.cdefault=e.id
left join sys.extended_properties g
on a.id=g.major_id AND a.colid = g.major_id
order by a.id,a.colorder
