select * from syscolumns a, sysobjects b where a.object_id=b.object_id and b.name='dingdan' and a.name not in('编号','datafilename')

报错，是因为我是sqlserver2005，没有obejct_id，而是id，所以改一下是：

select * from syscolumns a, sysobjects b where a.id=b.id and b.name='dingdan' and a.name not in('编号','datafilename')

这样就对了~~~

最后是这样：

declare  @c_sql varchar(8000) set @c_sql='' select @c_sql=@c_sql+ a.name+',' from syscolumns a, sysobjects b where a.id=b.id and b.name='dingdan' and a.name not in('编号','datafilename') set @c_sql=left(@c_sql,len(@c_sql)-1) select @c_sql set @c_sql='select '+@c_sql+' from dingdan' EXEC(@c_sql)
