PostgreSQL一次插入2個關係

Question

我有3個表professionals，services和feature_professional我需要在插入數據時插入professional。這是我試過的sql。

WITH professionals as (INSERT INTO professionals(id, company_id, first_name) 
VALUES (1, 1, 'peter') RETURNING *) 

INSERT INTO services(id, professional_id, name) 
VALUES (1, (select professionals.id from professionals), 'haircut'), 

INSERT INTO feature_professional(id, professional_id, feature_id, enabled) 
VALUES 
    (1, (select professionals.id from professionals), 1, true) 

我也試過不同的這種包裝所有插入語句，但仍然沒有運氣的變化。我得到的錯誤是syntax error。

ERROR: syntax error at or near "INSERT" 
LINE 106: INSERT INTO feature_professional 

完成此操作的正確語法是什麼？我知道如果我拿出第三個insert聲明，查詢就起作用了。例如：

WITH professionals as (INSERT INTO professionals(id, company_id, first_name) 
VALUES (1, 1, 'peter') RETURNING *) 

INSERT INTO services(id, professional_id, name) 
VALUES (1, (select professionals.id from professionals), 'haircut') 

Answer 1

你不能一個CTE後做了兩個插入，所以包裹每一個在不同的CTE

SQL DEMO

WITH professionals as (
    INSERT INTO professionals(id, company_id, first_name) 
    VALUES (1, 1, 'peter') RETURNING * 
), 
services as (
    INSERT INTO services(id, professional_id, name) 
    VALUES (1, (select professionals.id from professionals), 'haircut') 
) 
INSERT INTO features(id, professional_id, name) 
VALUES (1, (select professionals.id from professionals), 'autobook'); 

select * from professionals; 
select * from services; 
select * from features; 

Answer 2

INSERT INTO feature_professional (id, professional_id, feature_id, enabled) 
select ?, professionals.id from professionals, ?, ? 

前提是問號，你可以插入值。如果他們不是必需的，你可以忽略它們。

INSERT INTO feature_professional (professional_id) 
select professionals.id from professionals 

這裏是如何從選擇插入靜態值，而不是：
