无法使Codeigniter ODBC与select一起使用

Question

我一直在努力试图找出我现在做错了几天。我有一个ODBC连接设置一个辅助数据库，我严格从中选择数据。

所以我知道连接正在运行，并且我在活动记录中出错了。这是我的功能

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;  
}

显然，函数的第一部分我是jsut在活动记录之外运行查询然后我尝试使用活动记录完全相同的查询。当我打印第一个查询，外部活动记录时，我返回我期望的结果。但是当我打印$ query时，运行活动记录查询我得到以下内容：

CI_DB_odbc_result Object

    (

当我打印$ this-＆gt; histdb对象时，我得到以下内容：

我认为查询时间为0.1秒，这是否意味着查询运行了？让我真的很难搞清楚这一点，我无法弄清楚我对活动记录做错了什么。我对codeigniter很新。

谢谢尼克

尝试回显$ query-＆gt; result（）;并使用：

return $query->result();
