如何取得，一个库中，哪些表没有key。

我知道 sp_pkeys'table1' ，可以知道table1的key。

SELECT
(case when a.colorder=1 then d.name else '' end)表名,
a.colorder 字段序号,
a.name 字段名,
(case when COLUMNPROPERTY( a.id,a.name,'IsIdentity')=1 then '√'else '' end) 标识,
(case when (SELECT count(*)
FROM sysobjects
WHERE (name in
(SELECT name

(SELECT indid

WHERE (id = a.id) AND (colid in
(SELECT colid
FROM syscolumns
WHERE (id = a.id) AND (name = a.name))))))) AND
(xtype = 'PK'))>0 then '√' else '' end) 主键,
b.name 类型,
a.length 占用字节数,
COLUMNPROPERTY(a.id,a.name,'PRECISION') as 长度,
isnull(COLUMNPROPERTY(a.id,a.name,'Scale'),0) as 小数位数,
(case when a.isnullable=1 then '√'else '' end) 允许空,
isnull(e.text,'') 默认值,
isnull(g.[value],'') AS 字段说明

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<>'dtproperties'
left join syscomments e
on a.cdefault=e.id
left join sysproperties g
on a.id=g.id AND a.colid = g.smallid
order by a.id,a.colorder

try:

select object_name(o.id)
from sysobjects o
where o.type = 'U' and
not exists(select 1 from sysindexes i where i.id = o.id and i.status & 2048 = 2048)
