錯誤代碼：1137不能重新打開表：「amountforagents」

Question

請檢查下面

DELIMITER $$ 

    CREATE DEFINER=`ntc`@`%` PROCEDURE `new_procedure`(in v_Agentid int) 
BEGIN 

select (select @DayAmount :=sum(AmountRecevied) as Totoalamountperday from 
collection_master 
where AgentID=v_Agentid and day(Date_Time)= day(CURRENT_DATE())), 


(select @MonthAmount:=sum(AmountRecevied) as Totoalamountperday from 
collection_master 
where AgentID=v_Agentid and date_time between DATE_FORMAT(NOW() ,'%Y-%m-01') and LAST_DAY(now() - interval 0 month)), 



(select @YearAmount:= sum(AmountRecevied) as Totoalamountpermonth from 
collection_master 
where AgentID=v_Agentid and year(Date_Time) =YEAR(CURRENT_DATE())), 

(select @Position := @Position + 1 AS Rank from 
    collection_master ,(SELECT @Position := 0) r 
where AgentID=v_Agentid 
group by AgentID 
) as position; 
DROP TEMPORARY TABLE IF EXISTS amountforagents; 

create TEMPORARY table amountforagents (agentId int,DayAmount decimal,MonthAmount decimal,YearAmount decimal,Position int,totalamountreceived decimal); 
    set @agentId =v_Agentid; 
    update amountforagents SET totalamountreceived = (select ifnull(DayAmount,0)+ifnull(MonthAmount,0)+ifnull(YearAmount,0) from amountforagents where agentId=v_Agentid); 

INSERT Into amountforagents  
    (agentId,DayAmount,MonthAmount,YearAmount,Position,totalamountreceived) values(@agentId, 
@DayAmount,@MonthAmount,@YearAmount,@Position,@totalamountreceived); 


select agentId,DayAmount,MonthAmount,YearAmount,Position,totalamountreceived from amountforagents; 


END 

在這裏，我triing給我的順序通過SP爲totalamountreceived基於三列的總量在分配排名sp，這三列在temp表中，但它顯示錯誤錯誤代碼：1137無法重新打開表格：'amountforagents'

問題可能與您的子選擇朝向底部，在UPDATE聲明中。

正如你可以閱讀here on the mysql docs：

您不能引用到一個臨時表不止一次在同一 查詢。例如，下面不工作：

mysql> SELECT * FROM temp_table, temp_table AS t2; 
ERROR 1137: Can't reopen table: 'temp_table' 

如果您在 的指 臨時表中多次在不同 別名存儲功能，即使發生引用在不同的語句也會發生此錯誤功能。

您的UPDATE聲明似乎無法完成。您在創建表格後立即使用UPDATE（因此它將是空的），所以不會有任何問題。也許你的意思只是設置變量爲@totalamountreceived那裏呢？

嘗試刪除這一行：

update amountforagents 

然後修改SET語句來創建變量和值@totalamountreceived：

SET @totalamountreceived = ifnull(@DayAmount, 0) 
    + ifnull(@MonthAmount, 0) 
    + ifnull(@YearAmount, 0); 

這應該給你你後的結果，除非我誤解了你想要達成的目標。

一起：
