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");


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);


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!

//$id=12;<br />$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 />}

Dependency Injection in PHP: Code Examples for BeginnersDependency Injection in PHP: Code Examples for BeginnersMay 14, 2025 am 12:08 AM

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Dependency Injection vs. Service Locator in PHPDependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AM

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
