【问题描述】:
提示如何在 Sequelize 中使用 JOIN ? 我有以下代码:
db.User.findAll({
attributes: ['id'],
where: {vipEnd: {lt: expiresVip}, vip: true},
limit: 100,
order: 'id'
}).then(function(users) {
就4而言,是这样的:
SELECT "vkId" AS "id"
FROM "user" AS "user"
WHERE "user"."vipEnd" < 1469699683 --expiresVip
AND "user"."vip" = true
ORDER BY id
LIMIT '100';
如何达到这样的效果?
SELECT "vkId" AS "id"
FROM "user" AS "user"
LEFT JOIN "notification" ON "notification"."userId" = "user"."vkId"
WHERE "user"."vipEnd" < 1469699683
AND "user"."vip" = true
AND "notification"."type" = 4
AND "notification"."expiresVipDate" < 1469699683
ORDER BY id
LIMIT '100';
谢谢!
