將數據插入到兩個表中

Question

我想問我們如何在數據庫的多個表中插入數據。 我有2個表名爲大學和部門。

university 
uni_id |uni_name 

department 
dept_id|uni_id|dname 

uni_id是在部門外鍵和uni_id被設置爲在大學表自動遞增......

insert into university (uni_name) values ("any uni"); 
insert into department (uni_id,dname) values ("same as in uni_id in university table","any") 

我無法在所屬表（外鍵）來插入uni_id。同樣的問題在大學表中。

Answer 1

希望它會工作：

insert into university (uni_name) values ("any uni"); 
insert into department (uni_id,dname) values (LAST_INSERT_ID(),"any") 

Answer 2

你可以做到這一點通過插入與內選擇加入這樣的：

insert into department (uni_id,dname) 
select u.uni_id , "any" 
from university u 
inner join department d 
on d.uni_id = u.uni_id 

Answer 3

insert into university (uni_name) values ("any uni"); 

雖然插入部門表不

insert into department (uni_id,dname) 
select u.uni_id , "any" 
from university where uni_name = "any uni";
