如何将下面的SQL查询写入代码点火器

SELECT 
    `pm`.`id`, 
    `pm`.`region`,
    `pm`.`port_name`,
    `pm`.`country`,
    `tbl_port_annual_throughput`.`YEAR`,
    `tbl_port_annual_throughput`.`TOTAL_THROUGHPUT`,
    `tbl_port_annual_throughput`.`status`
    FROM (`tbl_port_annual_throughput`) 
    JOIN `port_master` pm 
      ON `pm`.`id` = `tbl_port_annual_throughput`.`PORT_ID` 
    WHERE `pm`.`country` = "100@Kenya" 
    AND (
        (`tbl_port_annual_throughput`.`YEAR` =  '2014' AND `tbl_port_annual_throughput`.`status` =  'Confirmed') 
        OR (`tbl_port_annual_throughput`.`YEAR` =  '2015' AND `tbl_port_annual_throughput`.`status` =  'Confirmed')
        OR (`tbl_port_annual_throughput`.`YEAR` =  '2016' AND `tbl_port_annual_throughput`.`status` =  'Confirmed')
    )

Answer 1

试试这个：

$or_where= "(`tbl_port_annual_throughput`.`YEAR` =  '2014' AND `tbl_port_annual_throughput`.`status` =  'Confirmed') OR (`tbl_port_annual_throughput`.`YEAR` =  '2015' AND `tbl_port_annual_throughput`.`status` =  'Confirmed') OR (`tbl_port_annual_throughput`.`YEAR` =  '2016' AND `tbl_port_annual_throughput`.`status` =  'Confirmed')";

            $this->db->select('pm.id, pm.region,pm.port_name,pm.country,tbl_port_annual_throughput.YEAR,tbl_port_annual_throughput.TOTAL_THROUGHPUT,tbl_port_annual_throughput.status');
            $this->db->join('port_master as pm','pm.id = tbl_port_annual_throughput.PORT_ID');
            $this->db->where('pm.country','100@Kenya');
            $this->db->where($or_where);
            return $this->db->get('tbl_port_annual_throughput')->result();

Answer 2

您可以使用查询构建器类：

$this->db->select
$this->db->from
$this->db->join

这些方法可用于在查询中执行相同的操作

在你转换它之前，实际的SQL需要一点点整理......

SELECT 
    `pm`.`id`, 
    `pm`.`region`,
    `pm`.`port_name`,
    `pm`.`country`,
    `pat`.`YEAR`,
    `pat`.`TOTAL_THROUGHPUT`,
    `pat`.`status`
    FROM `tbl_port_annual_throughput` pat 
    JOIN `port_master` pm 
      ON `pm`.`id` = `pat`.`PORT_ID` 
    WHERE `pm`.`country` = "100@Kenya" 
    AND `pat`.`YEAR` IN ('2014','2015','2016')
    AND `pat`.`status` =  'Confirmed'

所以现在它更简单，工作 - 快速模拟你的表格......

注意：请确保以上内容确实适用于您。

如果你真的想要你的确切查询，你可以做这样的事情

$query = $this->db
    ->select('pm.id, pm.region, pm.port_name, tbl_port_annual_throughput.YEAR, tbl_port_annual_throughput.TOTAL_THROUGHPUT, tbl_port_annual_throughput.status')
    ->from('tbl_port_annual_throughput')
    ->join('port_master pm', 'pm.id = tbl_port_annual_throughput.PORT_ID')
    ->where('pm.country','100@Kenya')
    ->group_start()
        ->group_start()
            ->where('tbl_port_annual_throughput.YEAR','2014')
            ->where('tbl_port_annual_throughput.status','Confirmed')
        ->group_end()
        ->or_group_start()
            ->where('tbl_port_annual_throughput.YEAR','2015')
            ->where('tbl_port_annual_throughput.status','Confirmed')
        ->group_end()
        ->or_group_start()
            ->where('tbl_port_annual_throughput.YEAR','2016')
            ->where('tbl_port_annual_throughput.status','Confirmed')
        ->group_end()
    ->group_end()
    ->get();

Answer 5

您可以执行此查询

$query = $this->db
    ->select('pm.id, pm.region, pm.port_name, tbl_port_annual_throughput.YEAR, tbl_port_annual_throughput.TOTAL_THROUGHPUT, tbl_port_annual_throughput.status')
    ->from('tbl_port_annual_throughput')
    ->join('port_master pm', 'pm.id = tbl_port_annual_throughput.PORT_ID')
    ->where('pm.country','100@Kenya')
    ->group_start()
        ->group_start()
            ->where('tbl_port_annual_throughput.YEAR','2014')
            ->where('tbl_port_annual_throughput.status','Confirmed')
        ->group_end()
    ->group_end()
    ->get();

Answer 6

    $wherearraydata1 = array('tbl_port_annual_throughput.YEAR' => '2014', 'tbl_port_annual_throughput.status' => 'Confirmed');
    $wherearraydata2 = array('tbl_port_annual_throughput.YEAR' => '2015', 'tbl_port_annual_throughput.status' => 'Confirmed');
    $wherearraydata3 = array('tbl_port_annual_throughput.YEAR' => '2016', 'tbl_port_annual_throughput.status' => 'Confirmed');


    $this->db->select('pm.id,pm.region,pm.port_name,pm.country,tbl_port_annual_throughput.YEAR,tbl_port_annual_throughput.TOTAL_THROUGHPUT,tbl_port_annual_throughput.status');
    $this->db->from('tbl_port_annual_throughput');
    $this->db->join('port_master', 'port_master.id = tbl_port_annual_throughput.PORT_ID');
    $this->db->where('pm.country','100@Kenya');        
    $this->db->where("( $wherearraydata1 OR $wherearraydata2 OR $wherearraydata3)");        
    $querydata = $this->db->get();

    return $querydata->result_array();
