TypeOrm으로 실행하면 원시 PostgreSQL 쿼리가 중단됨

Question

이 업데이트 쿼리를 만들고 있습니다.

await this.userRepository.query(
    `
        update "user" u
        set profile_pic = i.name
        from user_images_image uii
        inner join image i on uii."imageId" = i."id"
        where uii."userId" = u.id and u.id = ${userId} and i.id = ${imageId};
    `,
);

그리고 DB 클라이언트에서 동일한 쿼리를 실행해도 종료되지 않고 예상대로 작동합니다.

Answer 1

문제 해결 세션 후 다른 연결이 동일한 방법으로 다른 트랜잭션에 대해 관련 리소스 ( users의 외래 키 가있는 테이블 의 레코드)를 업데이트하려고 시도했기 때문에 쿼리가 잠 겼음을 발견했습니다 user_images_image. 둘 다 커밋 결과를 기다리고 있습니다. .

동일한 연결을 사용함으로써 우리는 올바른 행동을하게되었습니다.

문서에서 잠금 모니터링 쿼리 를 사용하여 알아 냈습니다 .
