-- 1. Lister tous les calendriers "Privée" avec leurs détails
SELECT 
    c.id,
    c.name,
    c.color,
    c.description,

LEFT JOIN "CalendarSync" cs ON cs."calendarId" = c.id
LEFT JOIN "MailCredentials" mc ON mc.id = cs."mailCredentialId"

-- 2. Voir tous les événements "Vendredi saint" avec leurs calendriers
SELECT

-- 3. Identifier les événements en double par externalEventId (même événement dans plusieurs calendriers)
SELECT

-- 4. Voir les détails complets des événements en double
SELECT

    HAVING COUNT(*) > 1
)

-- 5. Compter les événements par calendrier "Privée"
SELECT 
    c.id as "calendarId",
    c.name,
    COUNT(e.id) as "totalEvents",
    COUNT(CASE WHEN e."externalEventId" IS NOT NULL THEN 1 END) as "eventsWithExternalId",

FROM "Calendar" c
LEFT JOIN "Event" e ON e."calendarId" = c.id
WHERE c.name = 'Privée'
GROUP BY c.id, c.name
ORDER BY "totalEvents" DESC;

-- 6. Voir les événements "TEST de connaissances" (celui qui apparaît en double dans les logs)
SELECT 
    e.id,
    e.title,
    e."externalEventId",
    e."calendarId",
    c.name as "calendarName",

ORDER BY e."calendarId", e.start;

-- 7. Lister tous les CalendarSync pour les calendriers "Privée"
SELECT 
    cs.id,
    cs."calendarId",
    c.name as "calendarName",
    cs.provider,
    cs."externalCalendarId",

JOIN "Calendar" c ON c.id = cs."calendarId"
LEFT JOIN "MailCredentials" mc ON mc.id = cs."mailCredentialId"
WHERE c.name = 'Privée'
ORDER BY cs."createdAt" DESC;

-- 8. Trouver les événements sans externalEventId dans les calendriers Microsoft
SELECT 
    e.id,
    e.title,
    e."calendarId",
    c.name as "calendarName",
