生成数据库字典

2017/11/25 posted in  数据库

项目中客户需要数据库字典,可以用这个导出,先查询出来,然后复制到Excel表格里面

use YourDatabase  --指定要生成数据字典的数据库
go

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='要查询的表' --如果只查询指定表,加上此条件   
order by a.id,a.colorder
