我用BCB写一个程序，需要读取数据库中某张表的字段名称，通过SQL能取得到吗？如果不行的话，应如何作啊？请高手指点，最好能给一个简单例子！
在些先谢过大家了！
select name from dbo.syscolumns where id = object_id(你的表名)
select a.name from syscolumns a,sysobjects b where a.id=b.id and b.name=yourtable
select * from syscolumns where id=boject(Ntablename)
go
直接用SQL语句从系统表syscolumns中就可以读取到了:
select name from syscolumns where id=object_id(表名)
如果要详细的,就用:
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],)
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
select name from dbo.syscolumns where id = object_id(你的表名)
select * from yourtable where 1=2
or
select name from dbo.syscolumns where id = object_id(你的表名)
