如何使用 PHP Mysql 创建总帐/T-Account

Question

我正在尝试创建复式财务会计系统。我已经完成了它的数据库设计，请查看此链接以查看我的数据库图表。 http://i39.tinypic.com/juhbv6.png

我已经尝试了很多来开发 mysql 查询来生成总帐，但我没有接近。我所做的只是为一个帐户创建分类帐，而我必须为无限帐户创建。

我尝试过的查询如下：

 $this->db->select('*');
    $this->db->from('credit_side');
    $this->db->join('debit_side', ' debit_side.transaction_id_dr = credit_side.transaction_id_cr ');
    $this->db->join('transaction_info', 'transaction_info.transaction_id = credit_side.transaction_id_cr ');
    $this->db->join('accounts', 'accounts.code = credit_side.account_code ');
    $this->db->where('debit_side.account_code', '1001'); 
    $this->db->order_by('voucher_date','ASC');

在编写可以为所有帐户生成分类帐的 mysql 查询失败后，我写下了创建总帐/T 帐户的逻辑。

现在，请您帮我查询一下 mysql 吗？

请在执行以下操作之前检查数据库。 提前致谢:)

1. 从帐户中获取 accounts.name AS AccountHead、accounts.code。

2. 转到表debit_side和get debit_side.account_code， 如果debit_side.account_code=accounts.code 然后得到credit_side.account_code AS AccountName1（但是当我将在php中回显时，我想获取名称而不是代码本身）和credit_side.amount AS Amount1，SUM(credit_side.amount) AS TotalAmount1来自@ 987654333@ 其中debit_side.transaction_id_dr=credit_side.transaction_id_cr 并且transaction_info.voucher_date 在 date1 和 date2 之间 在哪里transaction_info.transaction_id=debit_side.transaction_id_dr

3. 完成第二步后转到表credit_side和get credit_side.account_code,
   如果credit_side.account_code=accounts.code 然后得到debit_side.account_code AS AccountName2（但是当我在php中回显时，我想获取名称而不是代码本身）和debit_side.amount AS Amount2，SUM(debit_side.amount) AS TotalAmount2 from @ 987654346@credit_side.transaction_id_cr=debit_side.transaction_id_dr 并且transaction_info.voucher_date 在 date1 和 date2 之间 在哪里transaction_info.transaction_id=credit_side.transaction_id_cr

现在在视图文件中，我的目标是：

   <table width="200" border="0">
     <tr><td colspan="5">Account Head <?echo $AccountHead ; ?> </td> </tr>


    <tr>
           <td>Dr.</td>
           <td>amount.</td>
            <td>&nbsp;</td>
           <td>Cr</td>
          <td>Amount</td>

    </tr>
     <tr>
       <td><?echo $AccountName1 ; ?></td>
       <td><?echo $Ammount1 ; ?></td>
      <td></td>
 <td><?echo $AccountName2 ; ?></td>
     <td><?echo $Ammount2 ; ?></td>

     </tr>

     <tr>
     <td>Total</td>
     <td><?echo $TotalAmount1 ; ?></td>
     <td>&nbsp;</td>
 <td>Total  </td>
 <td><?echo $TotalAmount2 ; ?></td>

     </tr>
     </table>

抱歉回复晚了，但这是您在做任何事情之前想要测试的完美东西。我想为此创建一个视图文件，但它似乎很复杂并且需要更多时间，目前我正在湖

这个解决方案可能会在我测试过的视图中让您感到厌烦，但是我曾经尝试将这两个查询结合起来并成功了。该查询可能看起来很复杂，但它正在获取完美的结果。 在这里

$data   =   array(
                  'debit_side.account_code    Code',
                  'group_concat(distinct accounts.name) as DebitAccount',
                  'group_concat(debit_side.amount) as DebitAmount',
                  'group_concat(transaction_info.voucher_date) as DebitVoucherDate',
                  '(SELECT group_concat(distinct accounts.name) as CreditAccount FROM (accounts)
                    left JOIN debit_side ON accounts.code = debit_side.account_code
                    left JOIN credit_side ON debit_side.transaction_id_dr = credit_side.transaction_id_cr
                    left JOIN transaction_info ON transaction_info.transaction_id = credit_side.transaction_id_cr
                    group by credit_side.account_code
                    having credit_side.account_code = `Code`) as CreditAccount',
                  '(SELECT  group_concat(credit_side.amount) as CreditAmount FROM (accounts)
                     left JOIN debit_side ON accounts.code = debit_side.account_code
                     left JOIN credit_side ON debit_side.transaction_id_dr = credit_side.transaction_id_cr
                     left JOIN transaction_info ON transaction_info.transaction_id = credit_side.transaction_id_cr
                   group by credit_side.account_code
                   having credit_side.account_code = `Code`) as CreditAmount',  
                  '(SELECT  group_concat(transaction_info.voucher_date) as CreditVoucherDate FROM (accounts)
                    left JOIN debit_side ON accounts.code = debit_side.account_code
                    left JOIN credit_side ON debit_side.transaction_id_dr = credit_side.transaction_id_cr
                    left JOIN transaction_info ON transaction_info.transaction_id = credit_side.transaction_id_cr
                    group by credit_side.account_code
                    having credit_side.account_code = `Code`) as CreditVoucherDate'

                );
    $this->db->select($data);
    $this->db->from('accounts');
    $this->db->join('credit_side','accounts.code = credit_side.account_code','left');
    $this->db->join('debit_side','debit_side.transaction_id_dr = credit_side.transaction_id_cr','left');
    $this->db->join('transaction_info','transaction_info.transaction_id = credit_side.transaction_id_cr','left');
    $this->db->group_by('debit_side.account_code');
    $this->db->order_by('debit_side.account_code','ASC');
    $query  =   $this->db->get();
    return  $query->result_array();

虽然这个查询工作正常，但这里是这个查询的修改和优化版本，我真的从这个查询中学到了东西，你也应该看看这个
