如何解決MySQL的CREATE FUNCTION查詢？

我想添加MySQL功能：如何解決MySQL的CREATE FUNCTION查詢？

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

，但得到的錯誤：

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

嘗試...

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$$

這有助於感謝; 但現在我得到錯誤：錯誤1418（HY000）：此函數在其聲明中沒有DETERMINISTIC，NO SQL或READS SQL DATA，並且二進制日誌記錄已啓用（您可能*希望使用不太安全的log_bin_trust_function_creators變量） – Liutas 2010-06-15 08:44:30

我找到答案。在「返回文本CHARSET utf8」之後，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$
