我现在有一个表employee,我在查询分析器中用什么命令能知道它的表结构.即它有哪些字段,这些字段的名称,类型,长度,允许为空?
我刚学SQL没多久,大家请帮忙!进来的人至少请UP一下再走,先谢谢了!

SELECT
表名=case when a.colorder=1 then d.name 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 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),
允许空=case when a.isnullable=1 then '√'else '' end,
默认值=isnull(e.text,''),
字段说明=isnull(g.[value],'')

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

select b.name ,c.name,b.length from sysobjects a,syscolumns b ,systypes c where b.id=a.id and a.name='employee' and c.xtype=b.xtype

[dlpseeyou]

select 名称 =b.name ,类型=c.name,长度=b.length,允许为空=(case b.isnullable when 1 then '√'else '' end) from sysobjects a,syscolumns b ,systypes c where b.id=a.id and a.name='test13' and c.xtype=b.xtype
