無法使Codeigniter ODBC與選擇一起工作

Question

我一直在努力尋找我現在做了幾天錯誤的工作。我有一個ODBC連接建立一個輔助數據庫，我嚴格選擇數據。

因此，我知道連接正在工作，並且在活動記錄中存在某些錯誤。這裏是我的功能

public function get_pm_counts($date, $date_equal='<=') {  
    //connect to the history server 
    $this->histdb = $this->load->database('locator', true); 

    $query = "SELECT query_name, pmcount, entry_date, company_code, orig_system FROM (pmcounts) WHERE plant_code = '2970' AND entry_date = '01/07/2014' AND pmcount > 0"; 
    $result = odbc_exec($this->histdb->conn_id, $query); 
    echo '<pre>'; 
    while ($row = odbc_fetch_array($result)) 
    { 
     print_r($row);   
     echo '<br>'; 
    } 
    echo '</pre>'; 

    //run the query        
    $this->histdb 
     ->select('query_name, pmcount, entry_date, company_code, orig_system') 
     ->where('plant_code', '2970') 
     ->where('entry_date '.$date_equal, $date) 
     ->where('pmcount >', 0); 
    $query = $this->histdb->get('pmcounts'); 
    print_r($this->histdb->last_query()); 
    return $query; 
} 

顯然函數的第一部分，我僅僅指剛運行的活動記錄外的查詢，然後我嘗試用活動記錄完全相同的查詢。當我打印第一個查詢時，在活動記錄外，我返回我期望的結果。但運行的活動記錄查詢我得到如下當我打印$查詢：

CI_DB_odbc_result Object 
(
[conn_id] => Resource id #8 
[result_id] => Resource id #10

    (

[custom_result_object] => Array 
    (

[current_row] => 0 
[num_rows] => 0 
[row_data] =>

當我打印$這個 - > histdb對象我得到以下內容：

我看到查詢時間爲0.1秒，這是否意味着查詢運行？讓我真的很難弄清楚這一點，我不知道我在做什麼錯誤的活動記錄。我對codeigniter相當陌生。

謝謝尼克

嘗試echo $ query-> result（）;用途：

return $query->result();
