mssql中怎么導(dǎo)出數(shù)據(jù)字典

本篇文章給大家分享的是有關(guān)mssql中怎么導(dǎo)出數(shù)據(jù)字典，小編覺(jué)得挺實(shí)用的，因此分享給大家學(xué)習(xí)，希望大家閱讀完這篇文章后可以有所收獲，話不多說(shuō)，跟著小編一起來(lái)看看吧。

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

 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(zhǎng)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(shuō)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

以上就是mssql中怎么導(dǎo)出數(shù)據(jù)字典，小編相信有部分知識(shí)點(diǎn)可能是我們?nèi)粘９ぷ鲿?huì)見(jiàn)到或用到的。希望你能通過(guò)這篇文章學(xué)到更多知識(shí)。更多詳情敬請(qǐng)關(guān)注億速云行業(yè)資訊頻道。
