codeigniter - 如何在两个表中查询两个变量并加入？

Question

我真的不擅长sql。

这种情况是我想搜索两个表中的数据。

这是我的模特。

public function get_commission_week($username, $weekId){

    $this->db->select('mc.clientId, mc.account,cb.weekId,cb.create_at');

    $this->db->from('tb_member_client mc', 'tb_commission_bonus cb');

    $this->db->where('mc.account', $username);
    $this->db->where('cb.weekId', $weekId);

    $this->db->join('tb_commission_bonus cb', 'cb.clientId = mc.clientId');

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

    return $query->result()->$row;

}

如何对具有本周用户名相关数据的数组进行SQL搜索？

试试这个：

public function get_commission_week($username, $weekId){

    $this->db->select('mc.clientId, mc.account,cb.weekId,cb.create_at');

    $this->db->from('tb_member_client mc');

    $this->db->where('mc.account', $username);
    $this->db->where('cb.weekId', $weekId);

    $this->db->join('tb_commission_bonus cb', 'cb.clientId = mc.clientId','left');

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

    return $query->result()->$row;

}
