mssql中怎么導出數據字典

本篇文章給大家分享的是有關mssql中怎么導出數據字典，小編覺得挺實用的，因此分享給大家學習，希望大家閱讀完這篇文章后可以有所收獲，話不多說，跟著小編一起來看看吧。

在你要導出數據字典的數據空中右鍵，新建查詢，執行如下代碼即可

 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, a.name 字段名, (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 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 占用字節數, COLUMNPROPERTY(a.id,a.name,'PRECISION') as 長度, isnull(COLUMNPROPERTY(a.id,a.name,'Scale'),0) as 小數位數, (case when a.isnullable=1 then '√'else '' end) 允許空, isnull(e.text,'') 默認值, 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
