查询sqlserver的数据库的数据结构,返回数据字典结果,可手动将查询的结果导出成excel等格式保存,下面这篇文章主要给大家介绍了关于SQLServer导出数据库字典的相关资料,需要的朋友可以参考下

SQL

直接修改带注释那行的表名称即可。

SELECT  
表名=case when a.colorder=1 then d.name else '' end, 
表说明=case when a.colorder=1 then isnull(f.value,'') else '' end,
字段序号=a.colorder, 
字段名=a.name, 
标识=case when COLUMNPROPERTY(a.id,a.name,'IsIdentity')=1 then '√'else '' end, 
主键=case when exists(SELECT 1 FROM sysobjects where xtype='PK' and name in (
  SELECT name FROM sysindexes WHERE indid in(
   SELECT indid FROM sysindexkeys WHERE id = a.id AND colid=a.colid 
   ))) then '√' else '' end, 
类型=b.name, 
占用字节数=a.length, 
长度=COLUMNPROPERTY(a.id,a.name,'PRECISION'), 
小数位数=isnull(COLUMNPROPERTY(a.id,a.name,'Scale'),0), 
允许空=case when a.isnullable=1 then '√'else '' end, 
默认值=isnull(e.text,''), 
字段说明=isnull(g.[value],'') 
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 sys.extended_properties g on a.id=g.major_id and a.colid=g.minor_id 
left join sys.extended_properties f on d.id=f.major_id and f.minor_id =0 
where d.name='girlSix' --如果只查询指定表,加上此条件  
order by a.id,a.colorder

测试sql

CREATE TABLE [dbo].[girlSix] (
[id] varchar(32) NOT NULL DEFAULT (replace(newid(),'-','')) ,
[createDate] datetime NOT NULL DEFAULT (getdate()) ,
[nickName] varchar(30) NOT NULL ,

)
 
 
GO
IF ((SELECT COUNT(*) from fn_listextendedproperty('MS_Description', 
'SCHEMA', N'dbo', 
'TABLE', N'girlSix', 
'COLUMN', N'nickName')) > 0) 
EXEC sp_updateextendedproperty @name = N'MS_Description', @value = N'名字'
, @level0type = 'SCHEMA', @level0name = N'dbo'
