mysql - cake php中的查询函数

Question

我正在用 php 编写代码，基本上将数据从 mySQL 数据库“映射”到另一个数据库。我使用的代码如下:

$results = $this->query("select PT_FS_DATA_ID from PATIENT_FLOWSHEET_DATA where 
    DT_LAST_UPDATED_TIME = (select top 1 DT_LAST_UPDATED_TIME from PATIENT_FLOWSHEET_DATA 
    order by DT_LAST_UPDATED TIME desc) group by PT_FS_DATA_ID;");

但是，我收到错误:

syntax error, unexpected T_VARIABLE, expecting T_FUNCTION

在我看来，这似乎是正确的语法。我在这里缺少什么吗？我尝试将 Controller 也放在那里$this->controllerName->query，但这也不起作用。

完整代码:

class CaExtraFlowsheetFields extends CaBase {
public $name = 'CaExtraFlowsheetFields';

/*
NOTE: This is to take all the fields in flowsheet and
maps their id's.
*/
//public $useTable = 'ANSWER_ENTRY';
public $useTable = 'PATIENT_FLOWSHEET_DATA';
public $primaryKey = 'PT_FS_DATA_ID';

protected function getPrimaryKeyValue(
    $hospital_id,
    $patient_id,
    $admission_id = null
) {

return $patient_id;
}

//*CHANGE BEGIN*
$results = $this->query("select PT_FS_DATA_ID from PATIENT_FLOWSHEET_DATA where 
DT_LAST_UPDATED_TIME = (select top 1 DT_LAST_UPDATED_TIME from PATIENT_FLOWSHEET_DATA 
order by DT_LAST_UPDATED TIME desc) group by PT_FS_DATA_ID;");

protected $filedMethodMappings = array(

    'Method_GO' => array(
        CaBase::KEY_MAPPING_LOGIC_COMPLEXITY => CaBase::LEVEL2_COMPLEXITY,
        CaBase::KEY_FIELD_LOGIC_NAME         => 'wsMethod_GO',
);

Answer 1

这是您正在做的事情:

class ABC {

    $result = 'whatever';

}

你不能在那里声明变量!

<小时/>

代码需要位于方法/函数内部...

class ABC
{
    public function wsMethod_GO ($params)
    {
        $result = 'whatever';
    }
}
