sql - Postgres Inner join insert into 和 select from 语法

Question

我正在尝试使用节点和 typescript 创建一个忘记密码的界面。我想将忘记密码 token 插入忘记密码数据库中，我正在使用以下查询来完成此操作。基本上我使用 guid 作为标记并尝试引用我的人员、派对和 contact_details 表

INSERT INTO 
dbo.forgot_password_tokens
    SELECT 
    'random_guid' as forgot_password_tokens_id, 
    current_timestamp as updated_at,
    cd.contact_details_id,
    u.users_id
        FROM
           dbo.users as u
           inner join dbo.people as pe on pe.people_id = u.people_id           
           inner join dbo.parties as pa on pa.parties_id = pa.parties_id  
           inner join dbo.contact_details as cd on
               cd.parties_id = pa.parties_id
               and cd.value = 'devin@email.com'
               and cd.contact_details_types_id in ('guid_for_email', 'guid_for_second_email')

这是我得到的错误

ERROR:  column "updated_at" is of type timestamp with time zone but expression is of type uuid

LINE 6:   cd.contact_details_id,

我不确定为什么它说 updated_at 得到了错误的数据，我认为 current_timestamp 会把它放在正确的位置

目标表中的列顺序可能与您选择的列顺序不匹配。这是一个很好的例子，说明了为什么您应该始终在insert 语句中指定列列表:

INSERT INTO dbo.forgot_password_tokens
   (forgot_password_tokens_id, updated_at, contact_details_id, users_id)
SELECT ...
FROM ...
