批量处理mysql数据时,如何在另一个表中插入所有记录?请高手能直接给出代码,谢谢!
.比如数据库member表中有若干条数据,想将每一条数据中的二个字段cca和ccb相加得到的和插入到另一字段ccd中:

cca   ccb    ccd        id
45      66      0          1
67      36      0         2
86      24      0         5
76      84      0         8
6        55       0        12
代码如下:

$obj_db->simplequery("update member set ccd=cca+ccb");
Copy after login


这样得到的结果是:
cca ccb ccd id
45 66 111 1
67 36 103 2
86 24 110 5
76 84 160 8
6 55 61 12
是我想要得到的结果。

但我还想将所有明细在另一表中记录下来,如果执行一条我会的:
$id=12;<br />$obj_db->simplequery("update member set ccd=cca+ccb  where id='$id'");<br /><br /><br />$q="select * from member where id='$id'";<br />$r=$obj_db->simplequery($q);<br />$a=$obj_db->fetchrow($r,DB_FETCHMODE_ASSOC);<br /><br />$mccd=$a[cca]+$a[ccb];<br /><br />$query="insert into mingxi (mid,mccd,mtime) values ('$id','$mccd','$time')";<br />$obj_db->simplequery($query);
Copy after login


得到:
mid mccd mtime id
12 61 1394963723 1


但如何批量得到:
mid mccd mtime id
1 111 1394963723 1
2 103 1394963723 2
5 110 1394963723 3
8 160 1394963723 4
12 61 1394963723 5

请高手帮忙给出详细代码,谢谢!
------解决方案--------------------
//$id=12;<br />$obj_db->simplequery("update member set ccd=cca+ccb ");<br /> <br /> <br />$q="select * from member'";<br />$r=$obj_db->simplequery($q);<br />while($a=$obj_db->fetchrow($r,DB_FETCHMODE_ASSOC)){<br />   $id=$a[id];<br />   $mccd=$a[cca]+$a[ccb];<br />   <br />   $query="insert into mingxi (mid,mccd,mtime) values ('$id','$mccd','$time')";<br />   $obj_db->simplequery($query);<br />}
Copy after login
