sql根据表名获取字段及对应说明

　　本文标签：表名,字段

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)
