先创建一个视图
Create view fielddesc
as
select o.name as table_name,c.name as field_name,t.name as type,c.length as
length,c.isnullable as isnullable,convert(varchar(30),p.value) as desp
from syscolumns c
join systypes t on c.xtype = t.xusertype
join sysobjects o on o.id=c.id
left join sysproperties p on p.smallid=c.colid and p.id=o.id
where o.xtype=@#U@#
查询时:
Select * from fielddesc where table_name = @#你的表名@#
还有个更强的语句，是邹建写的，也写出来吧
SELECT
(case when a.colorder=1 then d.name else @#@# end) N@#表名@#,
a.colorder N@#字段序号@#,
a.name N@#字段名@#,
(case when COLUMNPROPERTY( a.id,a.name,@#IsIdentity@#)=1 then @#√@#else @#@# end) N@#标识@#,
(case when (SELECT count(*)
FROM sysobjects
WHERE (name in
(SELECT name
FROM sysindexes
WHERE (id = a.id) AND (indid in
(SELECT indid
FROM sysindexkeys
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) N@#主键@#,
b.name N@#类型@#,
a.length N@#占用字节数@#,
COLUMNPROPERTY(a.id,a.name,@#PRECISION@#) as N@#长度@#,
isnull(COLUMNPROPERTY(a.id,a.name,@#Scale@#),0) as N@#小数位数@#,
(case when a.isnullable=1 then @#√@#else @#@# end) N@#允许空@#,
isnull(e.text,@#@#) N@#默认值@#,
isnull(g.[value],@#@#) AS N@#字段说明@#
--into ##tx
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 object_name(a.id),a.colorder
