How to list all projects in a specific Project Category
目的
To list all projects that are configured under a specific Project Category through a SQL query to the database.
ソリューション
次のクエリを実行します。
select distinct p.pname, p.pkey
from project p join nodeassociation n
on p.id=n.source_node_id
where n.sink_node_entity='ProjectCategory' and
n.sink_node_id=(select id from projectcategory where cname='Test')
order by p.pname; - Replace 'Test' with the project category name that you wish to list.
You may run an alternative query to fetch all projects with their Category:
select p.pname, p.pkey, pc.cname from project p
left join nodeassociation na on p.id=na.source_node_id and na.sink_node_entity='ProjectCategory'
left join projectcategory pc on na.sink_node_id = pc.id
group by p.pname, p.pkey, pc.cname;
This is tested using PostgreSQL. Please modify it according to the needs of your database.
