Chciałbym otrzymać: account_id, login, password, blocked, expired, nazwy wszystkich grup do których należy użytkownik i wszystkie role z tych poszczególnych grup (bez powtórzeń). Jak to zrobić?

Kombinuje tak ale może da się inaczej/szybciej...

[SQL] pobierz, plaintext 
SELECT account_id, login, password, blocked, expired, group_name, role_name FROM accounts INNER JOIN accounts_groups USING(account_id) INNER JOIN groups_roles USING(group_id) INNER JOIN groups USING(group_id) INNER JOIN roles USING (role_id);

A tutaj gotowa struktura bazy do testów:

wlasnie jestem na etapie tworzenia praw dostepu dla mojej zabawki, i mniej wiecej ten sam problem mi sie pojawil, troche sie uhahałem z tym ale tu masz rozwiazanie

pomogla ekipa z kanalu #php.pl

[SQL] pobierz, plaintext 
SELECT accounts.account_id, login, password, blocked, expired,
GROUP_CONCAT(DISTINCT group_name) AS 'grupy' , GROUP_CONCAT(DISTINCT role_name) AS 'role'
FROM groups_roles, roles, accounts_groups, accounts, groups 
 
WHERE groups_roles.role_id = roles.role_id AND groups_roles.group_id = accounts_groups.group_id AND accounts.account_id = accounts_groups.account_id AND groups.group_id = accounts_groups.group_id
 
GROUP BY accounts_groups.account_id

swoja droga w zrzucie tabel brakowalo ci roli13, co troszeczke mnie zmylilo (takie 15 min kombinowania)

@kukoc: wielkie dzięki bo to nie dawało mi spokoju - już myślałem że jest to nie możliwe i chciałem kombinować z podzapytaniami (raczej mało wydajne).

Mam jeszcze jedno pytanie: wiesz jak to przerobić na JOIN?

Tak czy inaczej masz wirtualnego browca

sorry nie wiem tak na szybko...

Problem podobny jak wcześniej tylko, że dochodzi nam tablica z parametrami. Dla konta jas powinno się otrzymać wynik:




Jak napisać takie zapytanie? Poniżej pełny kod SQL - wystarczy wkleić do mysql
