mysql逗號分隔List欄位轉多行

具體的邏輯我還沒整明白，先記上再說，親測可用。

select a1.id,a1.job_depends

from job_version_history a1
where a1.id in (1655,1656);

id    job_depends

1655    353,3,532
1656    484,5,567

select a1.id,a1.job_depends,substring_index(substring_index(a1.job_depends,',',a2.id+0),',',-1) job_depends_id

from job_version_history a1
join job a2 on a2.id < (length(a1.job_depends) - length(replace(a1.job_depends,',',''))+2)
where a1.id in (1655,1656);

id    job_depends    job_depends_id

1655    353,3,532    353
1655    353,3,532    3
1655    353,3,532    532
1656    484,5,567    484
1656    484,5,567    5
1656    484,5,567    567

select a11.job_id,

a11.job_name,
a11.job_owner_name,
a11.last_release_time,
a11.project_name,
a11.job_type,
group_concat(a11.job_depends_split_id) job_depends_id,
group_concat(a22.name) job_depends_name
from
(select a1.job_id,
a1.job_name,
a1.job_owner_name,
a1.job_release_time last_release_time,
a2.`name` project_name,
a1.job_type,
a1.job_depends,
substring_index(substring_index(a1.job_depends,',',a9.id+0),',',-1) job_depends_split_id
from job_version_history a1
left join project a2 on a1.project_id=a2.id
join job a9 on a9.id < (length(a1.job_depends) - length(replace(a1.job_depends,',',''))+2)
where a1.job_end_version = 2147483647) a11
left join job a22 on a11.job_depends_split_id=a22.id
group by a11.job_id,
a11.job_name,
a11.job_owner_name,
a11.last_release_time,
a11.project_name,
a11.job_type;

說明：合成以逗號分隔的多行轉一行關鍵字group_concat。
