先建立乙個檢視
create view fielddesc
asselect 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'
查詢時:
select * from fielddesc where table_name = '你的表名'
還有個更強的語句，是鄒建寫的，也寫出來吧
