mysql - 想要根据条件从两个表中检索数据......因此遇到问题需要指导

Question

我有两个表vms_vendor_job_submission表作为主表，第二个vms_offer表，主表主键是第二个表中的外键，所以我需要主表中job_id = 101和resume_status = 7的所有记录，它应该有第二个表中没有条目，或者如果存在条目，则其状态应为 2(已拒绝)。

select s.*
from vms_vendor_job_submission s left join
     vms_offer o 
     on s.id = o.submission_id and
        o.status = '2'
where s.job_id=".$_GET['job_id']." and s.resume_status='7'

Answer 1

我已经修复了它......并且工作正常

"SELECT s.* FROM vms_vendor_job_submission s 
LEFT JOIN vms_offer o 
ON s.id = o.submission_id 
WHERE s.job_id = 101 and if(s.id =o.submission_id, o.status = 2 and s.resume_status = '7',s.resume_status = '7')";
