Question

<?php

 $selectdelegatedtasks = "select delegation_cycle.delegation_cycle_id as task_id,delegation_cycle.delegate_from_id as from_id,delegation_cycle.delegate_to_id as to_id,delegation_cycle.time_estimate as main_time_estimate,delegation_cycle.status as main_task_status ,delegation_cycle.start_date as main_start_date,delegation_cycle.changes,DATE(delegation_cycle.delegated_time) as orginal_email_time,tasks.task_name,tasks.client_id,tasks.followup,tasks.task_owner,tasks.main_due_date,tasks.main_priority,1 as delegated,delegation_user_relation.showinlist,users.email as email_from,clients.client_name, @delegationcount:=(select count(delegation_cycle_id)  from delegation_cycle where delegation_cycle.task_id=tasks.task_id and delegation_cycle.task_parent='$loggeduserid') as delegationcount, @sumstatus:=(select sum(status)  from delegation_cycle where delegation_cycle.task_id=tasks.task_id and delegation_cycle.task_parent='$loggeduserid' and delegation_cycle.status='4') as sumstatus, (select count(notes_records_id) from notes_records join notes ON notes.notes_id = notes_records.notes_id where notes_to = '$loggeduserid'  and notes.task_id = delegation_cycle.task_id ) as notescount,(select count(notes_records_id) from notes_records join notes ON notes.notes_id = notes_records.notes_id where notes_to = '$loggeduserid' and notes.task_id = delegation_cycle.task_id  and  notes_records.read=0) as unreadnotescount from delegation_cycle inner join  tasks on tasks.task_id=delegation_cycle.task_id  inner join users on users.user_id=delegation_cycle.delegate_from_id inner join clients on clients.client_id=tasks.client_id join delegation_user_relation on delegation_user_relation.delegate_task_id=tasks.task_id where (case when delegation_cycle.status=3 ||  @delegationcount*4=@sumstatus then delegation_user_relation.user_id='$loggeduserid' and  delegation_cycle.delegate_to_id='$loggeduserid' and delegation_cycle.status!=4  else    (delegation_user_relation.showinlist=1 || delegation_user_relation.showinlist=2) and   delegation_user_relation.user_id='$loggeduserid'  and  delegation_cycle.delegate_to_id='$loggeduserid' and delegation_cycle.status!=4 end )";


        $resultqw1 = $this -> objDBConn -> exceuteQuery($selectdelegatedtasks);
        print_r($resultqw1);

?>   

$loggeduserid 被 4 替换，查询如下所示；

我正在使用这个查询，它在 mysql 工作台中运行良好，当我尝试从 php 页面执行此查询时，在 phpmyadmin 中它不起作用，请帮助我解决这个问题

在使用当前 session 之前需要设置临时 session 变量。
