问题：

即使在直接SQL查询工作时，JPQL throws也无法确定搜索的case语句的数据类型

我正试图通过以下方式更新一个表：

entityManager.createQuery(
        "UPDATE TestCaseExecutionDetailsEntity " +
        " SET status = " +
        " CASE WHEN (runOrder < :runOrder) THEN :completedStatus " +
        "      WHEN (runOrder = :runOrder) THEN :failedStatus " +
        "      WHEN (runOrder > :runOrder) THEN :abortedStatus " +
        " END " +
        " WHERE testExecutionJobId = :jobId")
    .setParameter("jobId", jobId)
    .setParameter("runOrder", runOrder)
    .setParameter("completedStatus", completed.name())
    .setParameter("failedStatus", failed.name())
    .setParameter("abortedStatus", aborted.name())
    .executeUpdate();

对于值jobid=1037和runorder=2，它抛出错误：

UPDATE TEST_CASE_EXECUTION_DETAILS tcxd
SET tcxd.STATUS =
CASE WHEN (tcxd.RUN_ORDER < 2) THEN 'completed'
WHEN (tcxd.RUN_ORDER = 2) THEN 'failed'
WHEN (tcxd.RUN_ORDER > 2) THEN 'aborted'
END
WHERE TEST_EXECUTION_JOB_ID = 1037;

java.lang.IllegalArgumentException: org.hibernate.QueryException: Could not determine data type for searched case statement [update com.pkg.dataaccess.model.TestCaseExecutionDetailsEntity tcede  set tcede.status =  CASE WHEN (tcede.runOrder < :runOrder) THEN :completedStatus       WHEN (tcede.runOrder = :runOrder) THEN :failedStatus       WHEN (tcede.runOrder > :runOrder) THEN :abortedStatus  END  WHERE tcede.testExecutionJobId = :jobId]

我在下面的查询中遇到了同样的问题。我只需在case语句中强制转换变量即可：

SELECT SUM(

)
