总帐样本

Question

我正在尝试创建一个双重入门财务会计系统。我已经为它完成了数据库的设计，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查询以生成总帐，但我没有得到任何关闭。我设法做的只是为一个帐户创建分类帐，我必须创建无限帐户。

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');

在编写了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，请你帮我解决mysql查询？

请在执行以下操作之前检查数据库。在此先感谢:)

从帐户中获取accounts.name AS AccountHead，accounts.code。
转到表debit_side和get debit_side.account_code， if debit_side.account_code = accounts.code然后获取credit_side.account_code AS AccountName1（但是当我在php中回显时，我想获取名称而不是代码本身）和credit_side.amount AS Amount1 ，来自SUM(credit_side.amount) credit_side = debit_side.transaction_id_dr的{{1}} AS TotalAmount1 credit_side.transaction_id_cr位于date1和date2之间在transaction_info.voucher_date = transaction_info.transaction_id
完成第二步后，转到表debit_side.transaction_id_dr和credit_side，
if get credit_side.account_code = credit_side.account_code然后获取accounts.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.account_code AS Amount2 ，debit_side.amount来自SUM(debit_side.amount)的{Total {1}} debit_side = credit_side.transaction_id_cr debit_side.transaction_id_dr位于date1和date2之间在transaction_info.voucher_date = transaction_info.transaction_id

现在在视图文件中我的目标是：

credit_side.transaction_id_cr

public function getDebits(){    
    $data   =   array(
                'debit_side.account_code DebitCode',
                'group_concat(distinct accounts.name) as DebitAccount',
                'group_concat(debit_side.amount) as DebitAmount',
                'group_concat(transaction_info.voucher_date) as DebitVoucherDate'
                );
    $this->db->select($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();
}


public  function getCredits()
{
    $data   =   array(
                'credit_side.account_code CreditCode',
                'group_concat(distinct accounts.name) as CreditAccount',
                'group_concat(credit_side.amount) as CreditAmount',
                'group_concat(transaction_info.voucher_date) as CreditVoucherDate'
                );
    $this->db->select($data);
    $this->db->from('accounts');
    $this->db->join('debit_side','accounts.code = debit_side.account_code','left');
    $this->db->join('credit_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('credit_side.account_code');
    $this->db->order_by('credit_side.account_code','ASC');
    $query  =   $this->db->get();
    return  $query->result_array();
}

很抱歉迟到的回复，但在你做任何事情之前，这是你想要测试的完美之物。我想为此创建一个视图文件，但它看起来很复杂，需要更多的时间，这一刻我湖

这个解决方案可能会让你对视图产生影响，因为我已经测试了它如何尝试将这两个查询结合起来并成功。查询可能看起来有些复杂，但它取得了完美的结果。这是

$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是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
