如何合并两个表并根据ID和子表中未引用的ID获取值

Question

这是我尝试过的查询

SELECT
applicants.Name,
GROUP_CONCAT(
    educationreference.SubjectPassed
) AS `Subject`,
GROUP_CONCAT(educationreference.College) AS `College`,
GROUP_CONCAT(
    YEAR(
        educationreference.DateObtained
    )
) AS `Date`
FROM
applicants,
educationreference
WHERE
applicants.PersonId = educationreference.PersonId
GROUP BY
applicants.PersonId
