如何在Laravel 4中编写此查询？

Question

我搜索网但我找不到解决问题的方法， 我是Codeigniter开发人员，现在我在Laravel开始了一个项目

我在Codeigniter Active记录中的查询是这样的：

public function show_brt($id = 0,$tax_cat_id,$lang="en") 
{
    $records = $this->db
            ->select('
                t1.id,
                t1.date_received, 
                t1.customer_name, 
                t1.memo, 
                t1.percent_tax_withheld, 
                t1.gross_invoice_amount, 
                t1.tax_amount_withheld, 
                t1.net_amount_received, 
                t1.tax_payment_date, 
                t2.rate, 
                t3.name_' . $lang. ' AS deposit_account'
                )
            ->from('brt AS t1')
            ->join('exchange_rate AS t2', 't2.id = t1.exchange_rate_id','left')
            ->join('balance_sheet_accounts AS t3', 't3.id = t1.deposit_account_id','left')
            ->where('t1.income_statement_account_id', $id)
            ->where('t1.tax_cat_id',$tax_cat_id)
            ->where('t1.company_id', $this->session->userdata('company_id'))
            ->where('t1.fiscal_year_id', $this->session->userdata('fiscal_year_id'))
            ->where('t1.user_id', $this->m_auth->get_user_id())
            ->get();

    if ($records->num_rows() > 0) {
        return $records;
    }
}

任何人都可以帮助我，我怎样才能像Laravel Eloquent或Fluent中的sql注入那样安全地编写这些查询。

试试这段代码：我基本上来自CI。我做了一次迁移。这可能不是最佳解决方案。我没有测试。

DB::table('brt AS t1')
     ->select('t1.id,
                t1.date_received, 
                t1.customer_name, 
                t1.memo, 
                t1.percent_tax_withheld, 
                t1.gross_invoice_amount, 
                t1.tax_amount_withheld, 
                t1.net_amount_received, 
                t1.tax_payment_date, 
                t2.rate, 
                t3.name_' . $lang. ' AS deposit_account'
            )
     ->leftjoin('exchange_rate AS t2', 't2.id', '=', 't1.exchange_rate_id')
     ->leftjoin('balance_sheet_accounts AS t3', 't3.id', '=', 't1.deposit_account_id')
     ->where('t1.income_statement_account_id', '=',$id)
     ->where('t1.income_statement_account_id','=', $id)
     ->where('t1.tax_cat_id','=',$tax_cat_id)
     ->where('t1.company_id','=', $this->session->userdata('company_id'))
     ->where('t1.fiscal_year_id','=', $this->session->userdata('fiscal_year_id'))
     ->where('t1.user_id','=', $this->m_auth->get_user_id())
     ->get();
