所以我有点卡在上面，我不断收到一个 sql server 错误。是的，我正在使用 mssql 服务器：| - 不是我的数据库。
一点背景，我关心的人际关系是这样的：
AssetMaintenanceRecord->(属于)->Asset->(属于)->Project->(有一个)->ProjectManager
（注意 ProjectManager 就像人员表的别名模型。项目表有一个 ProjectManager 的 ID，它只是人员 ID。
所以我试图做一个简单的过滤器，通过在 ProjectManager 上搜索来选择所有 AssetMaintenanceRecords。
AssetMaintenanceRecordsController.php 中的相关索引函数如下所示：
public function index() {
$conditions = NULL;
if (isset($this->params['url']['report']) && $this->params['url']['report'] == 'open') {
$conditions[] = array('CompletedDate' => NULL);
}
if (isset($this->params['url']['report']) && $this->params['url']['report'] == 'notified') {
$conditions[] = array('NotifiedDate BETWEEN ? AND ?' => array(date('M d Y g:iA', strtotime($this->params['url']['datefrom'])), date('M d Y g:iA', strtotime($this->params['url']['dateto']))));
}
if (isset($this->params['url']['report']) && $this->params['url']['report'] == 'completed') {
$conditions[] = array('CompletedDate BETWEEN ? AND ?' => array(date('M d Y g:iA', strtotime($this->params['url']['datefrom'])), date('M d Y g:iA', strtotime($this->params['url']['dateto']))));
}
if (isset($this->params['url']['project'])) {
$conditions[] = array('Asset.aCurrProject' => $this->params['url']['project']);
}
if (isset($this->params['url']['ptCode']) && $this->params['url']['ptCode'] != NULL) {
$conditions[] = array('Asset.ptCode' => $this->params['url']['ptCode']);
}
if (isset($this->params['url']['asset']) && $this->params['url']['asset'] != NULL) {
$conditions[] = array('Asset.aFullCode' => $this->params['url']['asset']);
}
if (isset($this->params['url']['pm']) && $this->params['url']['pm'] != NULL) {
$pm_search_terms = explode(' ', $this->params['url']['pm']);
foreach($pm_search_terms as $pm_search_term) {
$conditions[] = array(
'OR' => array(
'ProjectManager.PerGivenName LIKE' =>'%'.$pm_search_term.'%',
'ProjectManager.PerSurname LIKE' =>'%'.$pm_search_term.'%',
)
);
}
}
$this->paginate['AssetMaintenanceRecord'] = array(
'contain' => array(
'Asset' => array(
'Project' => array(
'ProjectManager'
))
),
'order' => 'CompletedDate ASC',
'limit' => 10
);
$planttype = $this->AssetMaintenanceRecord->Asset->PlantType->find('list');
$this->set(compact('planttype'));
$this->AssetMaintenanceRecord->recursive = -1;
$this->set('records', $this->paginate('AssetMaintenanceRecord', $conditions));
}
如果没有 ProjectManager 过滤器，它可以正常工作，我可以回显 ProjectManager 数组等，但是当我输入搜索词时，会出现以下错误：
无法绑定多部分标识符“ProjectManager.PerSurname”。
执行的 sql 如下所示：

对我来说看起来不错，但我显然在哪里出错了？
任何帮助表示赞赏。
