我是靠谱客的博主缓慢便当，这篇文章主要介绍sql根据表名获取字段及对应说明，现在分享给大家，希望可以做个参考。

复制代码代码如下:

 
SELECT 
TableName = OBJECT_NAME(c.object_id), 
ColumnsName = c.name, 
Description = ex.value, 
ColumnType=t.name, 
Length=c.max_length 
FROM 
sys.columns c 
LEFT OUTER JOIN 
sys.extended_properties ex 
ON 
ex.major_id = c.object_id 
AND ex.minor_id = c.column_id 
AND ex.name = 'MS_Description' 
left outer join 
systypes t 
on c.system_type_id=t.xtype 
WHERE 
OBJECTPROPERTY(c.object_id, 'IsMsShipped')=0 
AND OBJECT_NAME(c.object_id) ='tablename' 

1.获取所有数据库名:
Select Name FROM Master..SysDatabases orDER BY Name
2.获取所有表名:
Select Name FROM DatabaseName..SysObjects Where XType='U' orDER BY Name
XType='U':表示所有用户表;
XType='S':表示所有系统表;
3.获取所有字段名:
Select Name FROM SysColumns Where id=Object_Id('TableName')
