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代替，查詢如下所示;

正在使用此查詢，這在MySQL工作臺，在那裏，當我嘗試從PHP頁面，並在phpMyAdmin它不工作執行這個查詢，請幫我解決這個情況下運作良好

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

在我們使用它之前，需要爲當前會話設置臨時會話變量。
