MySQL：這個CREATE PROCEDURE語句有什麼問題？

Question

DROP PROCEDURE IF EXISTS CreateTopic; 
CREATE PROCEDURE CreateTopic 
(
    i_forum_id INT, 
    i_user_id INT, 
    i_title VARCHAR(255), 
    i_language VARCHAR(50), 
    i_content TEXT, 
    i_stickied TINYINT, 
    i_announce TINYINT, 
    i_closed TINYINT 
) 
BEGIN 
    INSERT INTO forum_topics (forum_id, user_id, title, language) 
     VALUES (i_forum_id, i_user_id, i_title, i_language); 
    SET @tid := LAST_INSERT_ID(); 
    INSERT INTO forum_posts (topic_id, user_id, subject, content) VALUES (@tid, i_user_id, i_title, i_content); 
    INSERT INTO core_logs (obj_id, user_id, type, action) VALUES (@tid, i_user_id, 'Topics', 'Topic Created'); 
END; 

我不確定它有什麼問題。 MySQL告訴我所有的東西都是不正確的，它只是不想被創建。而且，參數與它們各自的表格具有相同的類型和長度。

這是你的第一個「;」這打破了程序定義，mysql認爲你已經完成並對待任何事情「;」作爲另一個查詢。 您必須使用存儲過程的分隔符。

DELIMITER $$ 
DROP PROCEDURE IF EXISTS CreateTopic$$ 
CREATE PROCEDURE CreateTopic

有幾個問題。我希望我得到他們全部：

DROP PROCEDURE IF EXISTS CreateTopic; 
CREATE PROCEDURE CreateTopic 
(
    i_forum_id INT, 
    i_user_id INT, 
    i_title VARCHAR(255), 
    i_language VARCHAR(50), 
    i_content TEXT, 
    i_stickied TINYINT, 
    i_announce TINYINT, 
    i_closed TINYINT 
) 
BEGIN 
    DECLARE tid INT; 
    INSERT INTO forum_topics (`forum_id`, `user_id`, `title`, `language`) 
     VALUES (i_forum_id, i_user_id, i_title, i_language); 
    SET tid = LAST_INSERT_ID(); 
    INSERT INTO forum_posts (`topic_id`, `user_id`, `subject`, `content`) VALUES (tid, i_user_id, i_title, i_content); 
    INSERT INTO core_logs (`obj_id`, `user_id`, `type`, `action`) VALUES (tid, i_user_id, 'Topics', 'Topic Created'); 
END;
