当要查询表比较多时,手动写SQL就比较烦了,有一个办法就是通过,右键表+打开+查询来做,牙当方面,还有,多表链接,Left join等,
动态修改表结果,先打表设计器,做修改,然后,当击工具类的脚本图标,这里企业管理器自己会帮你生成需求的代码,
另
给大家一个得到表信息的SQL
SELECT
字段名=a.name,
类型=b.name,
占用字节数=a.length,
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='Info'
left join sysproperties g on a.id=g.id and a.colid=g.smallid
order by a.colorder
