基于syscolumns获得id所对应的表

查看字段所属表
select * from dbo.sysobjects where id in

       注意点:
     (a)这里为了主要杰出有个别重大内容,选用了中间几项音信输出。
     (b)syscolumns表中只包罗数据类型编号,要博得完整的名字须要从systypes表中找,日常客户使用的数据类型用xusertype对应相比较好,不会现出局地多的情景。
     (c)syscolumns.length获得的是大要内部存款和储蓄器的长短,所以nvarchar和varchar等体系在数据库中的显示是其一的四分之二。

4、取得表中主键所包含的列名:

    SELECT syscolumns.name FROM
syscolumns,sysobjects,sysindexes,sysindexkeys WHERE syscolumns.id =
object_id(‘tablename’) AND sysobjects.xtype = ‘PK’ AND
sysobjects.parent_obj = syscolumns.id AND sysindexes.id = syscolumns.id
AND sysobjects.name = sysindexes.name AND sysindexkeys.id =
syscolumns.id AND sysindexkeys.indid = sysindexes.indid AND
syscolumns.colid = sysindexkeys.colid

在乎:那是在4张系统表中寻觅的,关系相比复杂,大概能够象征为:
syscolumns中存有表中的列音讯和表id,sysobjects表中存有主键名字(即PK_Table雷同)和表id,sysindexes中存
有主键名字和表id和index编号,sysindexkeys中存有表id和index编号和列编号,一项一项对应起来后就能够找到列名了。

 

另外的SQL代码

select syscolumns.name,
systypes.name,
syscolumns.length from syscolumns   

  left join
systypes on syscolumns. xusertype
=systypes. xusertype
 

  where id=(select
id from sysobjects where name=’订货主档’卡塔尔(قطر‎;

go;

可能用那样的写法,施行结果一律:

select syscolumns.name,
systypes.name,
syscolumns.length from syscolumns,systypes

where (syscolumns.id=object_id(‘订货主档’State of Qatar and syscolumns.xusertype=systypes.xusertype)

order
by syscolumns.colorder;

go

推行结果:(字段只现出三回,符合规律)
