英文:
insert into table from the select query
问题
我尝试从选择查询中插入到postgresql表中，这里我有多个连接，我成功地从选择查询中获取到了数据，但当我运行insert时，出现了语法错误，错误消息是ERROR: syntax error at or near "select"
以下是我尝试的内容：
insert into pool_tags_tag ("poolId", "tagId") values (
select p.id as "poolId", t3.id as "tagId" from tag t3, pool p where t3.title in
(select q.topic as "questionTopic" from question q
join question_experience qe on qe."questionId" = q.id
join "question_jobRole" qjr ON qjr."questionId" = q.id
join tag t on t.id = qjr."tagId"
join tag t2 on t2.id = qe."tagId"
where t.title = 'FE' and t2.title = 'FRESHER')
and p.id=144 limit 1) ON CONFLICT ("poolId", "tagId") DO nothing
如果我删除插入查询，仅运行选择查询，我可以获取到poolId和tagId。
任何帮助或建议都将不胜感激。

You need to remove the VALUES clause because you're not actually passing some values but a SELECT statement:
insert into pool_tags_tag ("poolId", "tagId") SELECT p.id ...
