Question

我正在尝试使用createQueryBuilder运行以下类型的查询。我已验证所有实体均已正确创建并加入。但是，运行以下命令将返回一个空数组：

let apiKey = await getConnection()
    .createQueryBuilder()
    .from(ApiKey, "apiKey")
    .innerJoinAndSelect("apiKey.site", "site")
    .where("site.domain = :domain", { domain: "mysitename.com" })
    .andWhere("apiKey.key = :key", { key })
    .getMany()

但是！当我将getMany()替换为getSql()时，复制原始SQL并运行它，就可以了！我得到了我期望的结果：

SELECT "site"."id" AS "site_id", "site"."domain" AS "site_domain", "site"."name" AS "site_name", "site"."createdAt" AS "site_createdAt", "site"."apiKeyId" AS "site_apiKeyId", "site"."userId" AS "site_userId" FROM "api_key" "apiKey" INNER JOIN "site" "site" ON "site"."id"="apiKey"."siteId" WHERE "site"."domain" = 'mysitename.com'

我试图建立此查询的方式有什么明显的问题吗？

提前感谢您的帮助！

.getMany（）返回Promise of Entity []的类型，鉴于查询的性质，我怀疑您根本没有返回任何实体。尝试.getRawMany（）或.getRawAndEntities（）

当原始SQL工作时，TypeORM查询生成器返回空数组
