求一存储过程, 得到指定数据库中所有的主键,外键的对应关系表

[bwangel]

(主键表名,主键名称, 外键表名, 外键名称) 即可

[dawugui]

SELECT
表名 = case when a.colorder=1 then d.name else '' end,
表说明 = case when a.colorder=1 then isnull(f.value,'') else '' end,
字段序号 = a.colorder,
字段名 = a.name,
标识 = case when COLUMNPROPERTY( a.id,a.name,'IsIdentity')=1 then '√'else '' end,
主键 = case when exists(SELECT 1 FROM sysobjects where xtype='PK' and parent_obj=a.id and name in (
SELECT name FROM sysindexes WHERE indid in(
SELECT indid FROM sysindexkeys WHERE id = a.id AND colid=a.colid))) then '√' else '' end,
类型 = b.name,
占用字节数 = a.length,
长度 = COLUMNPROPERTY(a.id,a.name,'PRECISION'),
小数位数 = isnull(COLUMNPROPERTY(a.id,a.name,'Scale'),0),

数据库什么版本

[being21]

呵呵，什么版本？

在乌龟的基础上加个left join sysforeignkeys即可

代码太长，上面有的不写了

select ....,
IsNull(object_name(fk.fkeyid),'') as '外键表',
object_name(fk.constid) as '外键名称'
from ...
....
left join sysforeignkeys as fk on a.[name]=col_name(object_name('表名字'),rkey)

[sp4]

其实楼主需要的比较简单，只用sysobjects,syscolumns,sysforeignkeys就可以查询出来

[sp4]

有个地方写错。
col_name(object_name('表名字'),rkey)换成 col_name(object_id('表名字'),rkey)
----------------------------
select ....,
IsNull(object_name(fk.fkeyid),'') as '外键表',
object_name(fk.constid) as '外键名称'
from ...
....
left join sysforeignkeys as fk on a.[name]=col_name(object_id('表名字'),rkey)

select
	object_name(a.rkeyid) as [主键表名],
	b.name as [主键列名],
	object_name(a.fkeyid) as [外键表名],
	c.name as [外键列名]
from dbo.sysforeignkeys a
join dbo.syscolumns b
	on b.colid = a.rkey
		and b.id = a.rkeyid
join dbo.syscolumns c
	on c.colid = a.fkey
		and c.id = a.fkeyid
