PL/SQL触发器-firing问题3

Question

我试图回答这个问题：

创建一个显示“插入书”每次插入后触发。

我尝试：

create trigger insert_book after insert on Books 
for each rows 
begin 
insert into books (id_book,title) values(12,'book12'); 
end; 

Answer 1

试试这个....触发

CREATE TRIGGER insert_book ON [dbo].[Books] 
FOR INSERT 
AS 
    insert into books (id_book,title) values(12,'book12'); 
    PRINT 'Insert Book' 
GO
