我在postgres数据库上使用以下查询:
insert into user_settings (google_access_token, google_refresh_token)
select 'google_access_token', 'google_refresh_token' from user
where id = user_id
table user_settings有一个字段user_id
,对应于用户表中名为id
的字段。但这会给出错误:
column "user_id" does not exist
Hint: There is a column named "user_id" in table "user_settings",
but it cannot be referenced from this part of the query

我想你需要这样做:
insert into user_settings (google_access_token, google_refresh_token)
select 'google_access_token',
'google_refresh_token'
from user
where id in (select user_id from user_settings )

您正在使用user_settings中的列并使用条件插入该表。 我认为您必须使用update语句,因为您的条件是
user .id = user_settings .user_id

即使您没有匹配的值,也可以使用NULL更新表
update user_settings
set
user_settings.google_access_token='google_access_token',
user_settings.google_refresh_token='google_refresh_token'
from user_settings
inner join user
on user_settings.user_id=user.id
