从选择查询插入表

Question

我试图从选择查询插入

postgresql

表，这里我有多个连接，我成功地设法从选择查询中获取数据，但是当我运行

insert

时得到语法错误

ERROR: syntax error at or near "select"

下面是我试过的

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并只运行选择我得到

poolId

和

tagId

真的很感激任何帮助或建议

您需要删除

VALUES

子句，因为您实际上并没有传递一些实际值，而是传递了一个

SELECT

语句：

insert into pool_tags_tag ("poolId", "tagId") SELECT p.id ...
