  前端时间,有个同事离职了。然后在交接的过程中,数据库文档的缺乏一直是我心中的一个梗。然后就花了些时间写了个小工具。先上效果吧。

界面效果:

下面放一些关键的SQL代码:

获取某个数据库里的所有表:

1 select newid() as Id,isnull(f.value,‘‘) as Remark,Table as ObjectType,
2             Row_Number() over ( order by t.id )  as SortId,t.id as ObjectId,t.name as ObjectName,‘‘ as Contents
3             from   sysobjects  as t left outer  join sys.extended_properties   f  on t.id = f.major_id 
4             and f.minor_id = 0 where t.xtype = U AND t.status >= 0 and t.name<>sysdiagrams

对于上面的一些图上都是马赛克,我只能表示抱歉!

如果你对于这些SQL语句有更好的实现方式,欢迎评论、小纸条。
