Przepraszamy za spóźnioną odpowiedź, ale jest to idealna rzecz, którą chcesz przetestować, zanim cokolwiek zrobisz. chciałem utworzyć plik widoku do tego, ale wydaje się to skomplikowane i zajmuje więcej czasu, niż w tej chwili

EDYTOWANE

To rozwiązanie może męczyć Cię w widoku, ponieważ je testowałem. Jakkolwiek próbowałem połączyć te dwa zapytania i udało mi się. Zapytanie może wyglądać na coś złożonego, ale przynosi doskonałe wyniki.Oto

$data   =   array(
                  'debit_side.account_code    Code',
                  'group_concat(distinct accounts.name) as DebitAccount',
                  'group_concat(debit_side.amount) as DebitAmount',
                  'group_concat(transaction_info.voucher_date) as DebitVoucherDate',
                  '(SELECT group_concat(distinct accounts.name) as CreditAccount FROM (accounts)

Chociaż to zapytanie działa dobrze, ale tutaj jest zmodyfikowana i zoptymalizowana wersja tego zapytania. Naprawdę nauczyłem się rzeczy z tego zapytania, powinieneś również na to spojrzeć

Dziwne zachowanie grupy w zapytaniu, które wymaga optymalizacji
