SQL学习笔记之显示用户表和用户表的结构

下面是用sql语句显示数据库中所有的用户表。

select [id], [name] from [sysobjects] where [type] = 'u' and status>0

查询所有用户表的结构，这个语句在编写数据字典时很有用哦。如果想只显示一个表的话就在条件后面直接写上表名就可以了。

SELECT table_name as '表名',column_name as '列名',data_type as '类型',

character_maximum_length as '长度',column_default as '默认值',is_nullable as '是否为空'

FROM INFORMATION_SCHEMA.COLUMNS

where table_name in(select name from sysobjects where xtype='u' and status>0)

order by table_name
