我正在 Oracle 中创建一个过程来搜索参数中指定的一些关键字并打印出该行。这是我下面的代码。它有效,但我不知道为什么它不断打印最后一行两次。请帮忙
CREATE TABLE Testimonial( TestimonialID integer PRIMARY KEY,
Content char(100));
INSERT INTO Testimonial VALUES (100,'Great website');
INSERT INTO Testimonial VALUES (101,'I like it');
INSERT INTO Testimonial VALUES (102,'I bought two items from here and I really like them');
INSERT INTO Testimonial VALUES (103,'My girlfriends likes my presents I bought here');
INSERT INTO Testimonial VALUES (104,'Nice products');
INSERT INTO Testimonial VALUES (105,'Friendly customer service');
COMMIT;
Create or replace procedure Search_Testimonials (search_string IN char)
IS
Testimonial_record Testimonial%ROWTYPE;
cursor cur_Testimonial is
select *
from Testimonial
WHERE content LIKE '%' || search_string || '%';
BEGIN
open cur_Testimonial;
Loop
Fetch cur_Testimonial into Testimonial_record;
DBMS_OUTPUT.PUT_LINE( 'Content: ' || Testimonial_record.content );
EXIT WHEN cur_Testimonial%NOTFOUND;
END LOOP;
close cur_Testimonial;
COMMIT;
END;
/
set serveroutput on
exec Search_Testimonials('bought')
输出
Content: I bought two items from here and I really like them
Content: My girlfriends likes my presents I bought here
Content: My girlfriends likes my presents I bought here
