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’)
