id mysql quot select

mysql复制某一条记录
$sql="insert into table1 (*) select * from table1 where id=$id";


上面是错误的

1.ID自动增加
2.复制所有字段内容

请问要怎么完善。

------解决方案--------------------
你需要开列除 id 以外的字段名
------解决方案--------------------
复制的字段要对应你的inser into tablename1(a,b) select a,b from tablename
------解决方案--------------------
如果不想手工开列字段,可以使用程序来做
由于有主键,不开列是不行的
何况 mysql 一直建议:为了提高效率,请开列所需字段,而不是简单的 * 一下
------解决方案--------------------
就跟平常写入一样,必须字段值相对应
