活動記錄我有活動記錄笨第二版王氏特殊標準這樣一個問題:CONCAT病情左加入笨

$this->db->select('t_po_detail_item, t_process_shif, m_machine_lines, m_machine_mac, t_po_detail_no, 
         t_prod_lot, CONCAT(t_prod_lot, "-", t_prod_sublot) AS nolot, 
         COUNT(t_prod_sublot) AS qtybox, SUM(t_process_qty) AS qtypcs, 
         ROUND((SUM(t_process_qty)*m_process_weight)/1000,1) AS qtyberat', FALSE); 
    $this->db->join(self::$table2, 't_process_prod_id = t_prod_id', 'left') 
      ->join(self::$table3, 't_prod_lot = t_po_detail_lot_no', 'left') 
      ->join(self::$table5, 't_process_machine = m_machine_id', 'left') 
      ->join(self::$table4, 'CONCAT_WS("-",t_po_detail_item, t_process_cat) = CONCAT_WS("-",m_process_id, m_process_proc_cat_id)', 'left'); 
    $this->db->where('t_process_cat', 16); 
    $this->db->group_by('nolot'); 
    $query = $this->db->get(self::$table1); 

有有特殊的標準,加入與CONCAT WS條件。如果我使用標準查詢mysql,查詢運行正常。

$sql = 'SELECT t_po_detail_item, t_process_shif, m_machine_lines, m_machine_mac, t_po_detail_no, t_prod_lot, CONCAT_WS("-",t_prod_lot, t_prod_sublot) AS nolot, 
      COUNT(t_prod_sublot) AS qtybox, SUM(t_process_qty) AS qtypcs, ROUND((SUM(t_process_qty)*m_process_weight)/1000,1) AS qtyberat 
      FROM `t_process` 
      LEFT JOIN t_prod ON t_process_prod_id = t_prod_id 
      LEFT JOIN t_po_detail ON t_prod_lot = t_po_detail_lot_no 
      LEFT JOIN m_machine ON t_process_machine = m_machine_id 
      LEFT JOIN m_process ON CONCAT_WS("-",t_po_detail_item, t_process_cat) = CONCAT_WS("-",m_process_id, m_process_proc_cat_id) 
      WHERE t_process_cat=16 
      GROUP BY(nolot)'; 

    $query = $this->db->query($sql); 

我的活動記錄代碼有錯誤嗎? 關於,

嘗試$這個 - > DB-> last_query();並在查詢 – Rijin

仍然錯誤..檢查差異位置此代碼? – NeoS

在Codeigniter查詢生成器中使用MySQL函數時,您需要在引號""之外的函數,因此您需要傳遞可選的第四個參數來加入,而不是要跳過輸入,而您的查詢變爲

$this->db->join($table, $condition, $join_type, false);

我使用'$ this-> db-> join($ table,$ condition,$ join_type,false);'但仍然錯誤 – NeoS
