Question

我需要帮助，我在codeIgniter上有这样的查询

select * 
from meter_list 
where metertimestamp BETWEEN 
                     to_date('2010/03/15 05:06', 'YYYY/MM/DD HH24:MI') 
                     and 
                     to_date('2015/03/15 05:06', 'YYYY/MM/DD HH24:MI');

我在我的代码中尝试这样：

$this->_db_oracle->where('METERTIMESTAMP >=', $tgl1);
$this->_db_oracle->where('METERTIMESTAMP <=', $tgl2);
$query = $this->_db_oracle->get('MTR_METERLIST');

但我收到以下错误：

错误号码：

SELECT * FROM＆＃34; MTR_METERLIST＆＃34;在哪里＆＃34; METERTIMESTAMP＆＃34; ＆GT; 0和＆＃34; METERTIMESTAMP＆＃34; ＆LT; 0

行号：330

请帮助解决我的代码。抱歉我的英文不好，谢谢

只需尝试使用代码并在oracle上使用“查询”来获取fire SQL。像：

  public function __construct(){
            $this->CI =& get_instance();
            $this->_KISS_DB = $this->CI->load->database('kiss', TRUE);
    }

    function current_semester(){

            $strSQL = "select * from meter_list where metertimestamp BETWEEN 
                         to_date('2010/03/15 05:06', 'YYYY/MM/DD HH24:MI') 
                         and 
                         to_date('2015/03/15 05:06', 'YYYY/MM/DD HH24:MI') ";

            $query = $this->_KISS_DB->query($strSQL);

            foreach ($query->result() as $row)
            {
               echo $row->COURSE_CODE;
            }
    }

如何在CodeIgniter上的两个日期之间查询oracle
