MySQL: не удается получить доступ к временной таблице

Question

я написал этот MySQL хранимой процедуру (Полную процедуру в конце вопроса), и это дает мне ошибку в следующих утверждениях:

UPDATE TrialBalTbl 
    SET totalCred = (SELECT SUM(DISTINCT L1CredSUM) FROM TrialBalTbl), 
     totalDeb = (SELECT SUM(DISTINCT L1DebSUM) FROM TrialBalTbl); 

была ошибкой:

не удается открыть заново таблицу

(TrialBalTbl это временная таблица) Я искал над ним и нашел that

Вы не можете обратиться к ВРЕМЕННОЙ таблице более чем один раз в одном запросе

Так я думал использовать псевдоним tbal для временной таблицы TrialBalTbl для достижения эффекта и пришел с этим:

UPDATE TrialBalTbl as tbal 
SET totalCred = (SELECT SUM(DISTINCT L1CredSUM) FROM tbal), 
     totalDeb = (SELECT SUM(DISTINCT L1DebSUM) FROM tbal); 

Теперь, к сожалению, это тоже не сработает. Это говорит

Таблица «digitalmanager.tbal» не существует

Может кто-нибудь пожалуйста, скажите мне, что случилось с ним? И как я могу заставить это работать? Вот моя полная хранимая процедура, которая работает до этого UPDATE заявления:

Answer 1

Вы могли бы сделать это с помощью переменного.

Объявляются две переменные в начале вашей процедуры:

DECLARE @CredSUM decimal(19,2); 
DECLARE @DebSUM decimal(19,2); 

Затем установите их и обновить временную таблицу, используя их:

SET @CredSUM = (SELECT SUM(DISTINCT L1CredSUM) FROM TrialBalTbl); 
SET @DebSUM = (SELECT SUM(DISTINCT L1DebSUM) FROM TrialBalTbl); 

UPDATE TrialBalTbl SET 
    totalCred = @CredSUM, 
    totalDeb = @DebSUM 
;
