mysql - 我尝试使用 JPA 查询中的内部联接更新一些记录，但出现一些异常

Question

这是 MySQL 查询:

UPDATE grademyadvisor.gma_error AS ge
        INNER JOIN
    grademyadvisor.yodlee_error_code AS yec ON yec.id = ge.yodlee_error_id 
SET 
    ge.is_resolved = 0
WHERE
    ge.client_id = 639
        AND yec.error_code = 402;

Spring Data JPA Query And getting Exception. Caused by: java.lang.IllegalArgumentException: org.hibernate.hql.internal.ast.QuerySyntaxException: expecting "set", found 'INNER' near line 1, column 39 [ UPDATE com.gma.domain.GMAError AS ge INNER JOIN ge.yodleeErrorCode AS yec SET ge.isResolved=:isResolved WHERE ge.client.id=:clientId AND yec.errorCode=:errorCode ]

@Query(" UPDATE GMAError AS ge "
        + "INNER JOIN ge.yodleeErrorCode AS yec "
        + "SET ge.isResolved=:isResolved "
        + "WHERE ge.client.id=:clientId "
        + "AND yec.errorCode=:errorCode ")

Answer 1

在 WHERE 子句中使用子查询来消除 INNER JOIN 语句:

UPDATE grademyadvisor.gma_error
SET 
    is_resolved = 0
WHERE
    client_id = 639
AND yodlee_error_id = (SELECT id FROM grademyadvisor.yodlee_error_code WHERE error_code = 402);
