我有以下查询，
SELECT v.pattern_id,
v.id,
v.pdb_id AS viocardId,
p.pdb_id AS PID,
s.vio_id AS SiVioId,
r.date AS orcdate,
s.created_date AS sivcreateddate,
r.job_id,
r.maskset,
r.device,
d.tech_geometry,
r.layer,
r.layer_rev,
r.ptrf,
r.operation,
Concat_ws('_', d.tech_geometry, r.layer, p.pdb_id) AS techlayer
FROM orc_orcviolation v,
orc_orcpattern p,
siverify_siverifyverificationsite s,
orc_orccheck o,
orc_orcrecord r,
siverify_siverifyverificationdevice d
WHERE v.pattern_id = p.id
AND p.pdb_id = s.pattern_id
AND p.if_target = s.if_target
AND p.if_secure <> 1
AND s.create_status <> 5
AND v.check_id = o.id
AND o.record_id = r.id
AND d.id = s.si_device_id
AND r.maskset <> 'MT23RUN1'
AND r.maskset <> 'M25RUN3'
AND r.ptrf NOT LIKE '%PTRF-20251-%'
AND d.fab LIKE '%FAB 1%'
AND v.id > (SELECT v1.id
FROM orc_orcviolation v1,
orc_orcpattern p1,
siverify_siverifyverificationsite s1,
orc_orccheck o1,
orc_orcrecord r1,
siverify_siverifyverificationdevice d1
WHERE v1.pattern_id = p1.id
AND p1.pdb_id = s1.pattern_id
AND p1.if_target = s1.if_target
AND p1.if_secure <> 1
AND s1.create_status <> 5
AND v1.check_id = o1.id
AND o1.record_id = r1.id
AND d1.id = s1.si_device_id
AND r1.maskset <> 'MT23RUN1'
AND r1.maskset <> 'M25RUN3'
AND r1.ptrf NOT LIKE '%PTRF-20251-%'
AND d1.fab LIKE '%FAB 1%'
AND v1.id = s1.vio_id
AND s1.vio_id = s.vio_id)
AND r.date > s.created_date;
我需要的是，我需要为列r.job_id获取不同的值。我对上述查询的输出看起来像是
pattern_id id viocardId PID SiVioId orcdate sivcreateddate job_id maskset device tech_geometry layer layer_rev ptrf operation techlayer

在上面的操作中，对于PID（4298455），我们可以看到三个job_id（442896,471956,504071）。我想删除job_ids的重复，理想情况下我的操作应该是，
pattern_id id viocardId PID SiVioId orcdate sivcreateddate job_id maskset device tech_geometry layer layer_rev ptrf operation techlayer

我不认为仅为r.job_id的不同值创建子查询是明智的选择，因为它可能会干扰查询的其他部分。有什么办法吗？提前谢谢。
