如何解决MySQL的CREATE FUNCTION查询？

我想添加MySQL功能：如何解决MySQL的CREATE FUNCTION查询？

CREATE FUNCTION `chf_get_translation`(translation_id INT, site_lang INT) 
RETURNS text CHARSET utf8 
BEGIN 

    DECLARE translation TEXT; 

    SELECT title 
    INTO translation 
    FROM chf_translations 
    WHERE key_id = translation_id 
    AND lang_id = site_lang; 

    RETURN translation; 

END

，但得到的错误：

1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 3

尝试...

DELIMITER $$ 

CREATE FUNCTION `chf_get_translation`(translation_id INT, site_lang INT) 
RETURNS text CHARSET utf8 
BEGIN 

    DECLARE translation TEXT; 

    SELECT title 
    INTO translation 
    FROM chf_translations 
    WHERE key_id = translation_id 
    AND lang_id = site_lang; 

    RETURN translation; 

END$$

这有助于感谢; 但现在我得到错误：错误1418（HY000）：此函数在其声明中没有DETERMINISTIC，NO SQL或READS SQL DATA，并且二进制日志记录已启用（您可能*希望使用不太安全的log_bin_trust_function_creators变量） – Liutas 2010-06-15 08:44:30

我找到答案。在“返回文本CHARSET utf8”之后，我需要“READS SQL DATA” – Liutas 2010-06-15 08:55:53

DELIMITER $ 

CREATE FUNCTION `chf_get_translation`(translation_id INT, site_lang INT) 
RETURNS text CHARSET utf8 
DETERMINISTIC 
BEGIN 

    DECLARE translation TEXT; 

    SELECT title 
    INTO translation 
    FROM chf_translations 
    WHERE key_id = translation_id 
    AND lang_id = site_lang; 

    RETURN translation; 

END$
