试算表更新占

Question

我期待更新我chartofaccount在这里得到一个试算什么，我有chartofaccount的表

Id    parent   Debit   Credit 

1 
10    1    
101    10 
1011   101       30 
101121231  1011   40 
101134121  1011   20 

我需要的表看起来像这样

Id    parent   Debit   Credit 

1        60    30 
10    1    60    30 
101    10   60    30 
1011   101   60    30 
101121231  1011   40 
101134121  1011   20 

的想法是，我需要总结帐户ID相对于父

这里是什么使用，但它只是更新1记录

$select2="SELECT sum(debit),sum(credit),parent 
        FROM chartofaccount 
        group by parent 
        ORDER BY parent DESC"; 
    $run2=mysql_query($select2,$con); 
    if(!$run2)die("ERROR22".mysql_error()); 

    for($counter=0;$row1=mysql_fetch_array($run2);$counter++){ 

     $parentid=$row1[2]; 
     $update3="UPDATE chartofaccount 
        SET debit='$row1[0]', 
         credit='$row1[1]' 
         WHERE Id='$parentid'"; 
     $run3=mysql_query($update3,$con); 
     if(!$run3)die("ERROR1".mysql_error()); 

    } 

Answer 1

$select2="SELECT Distinct(parent) FROM chartofaccount 
          ORDER BY parent DESC"; 
      $run2=mysql_query($select2,$con); 
      if(!$run2)die("ERROR22".mysql_error()); 

      for($counter=0;$row1=mysql_fetch_assoc($run2);$counter++){ 

       $parentid=$row1['parent']; 

       $select3="SELECT sum(debit),sum(credit),parent 
          FROM chartofaccount 
          WHERE parent='$parentid' 
          group by parent"; 
       $run3=mysql_query($select3,$con); 
       if(!$run3)die("ERROR22".mysql_error()); 

       for($counter=0;$row2=mysql_fetch_array($run3);$counter++){ 

         $parentidz=$row2[2]; 

          $update3="UPDATE chartofaccount 
             SET debit='$row2[0]', 
              credit='$row2[1]' 
              WHERE Id='$parentidz'"; 
          $run4=mysql_query($update3,$con); 
          if(!$run4)die("ERROR1".mysql_error()); 
       } 
      }
