MySQL - #2014 - 當我在 PHPMyAdmin 中調用存儲過程時命令不同步

Question

晚上好，

這是我的存儲過程（編譯成功）：

    DELIMITER $$
    CREATE OR REPLACE PROCEDURE GetStringOptionList (IN p_infoTypeCode VARCHAR(15), IN p_language VARCHAR(1))

    BEGIN
      DECLARE v_infotype_code          VARCHAR(15);
      DECLARE v_infotype_description   VARCHAR(50);
      DECLARE v_stringopt_code         VARCHAR(15);
      DECLARE v_stringopt_description  VARCHAR(50);
      DECLARE v_noMoreRow              INTEGER;
      DECLARE cur_stringOptions   
                 
                 CURSOR FOR     
                 SELECT infoType.code as 'infoTypeCode', 
                        case when p_language = 'F' then infoType.frenchDescription
                             when p_language = 'E' then infoType.englishDescription 
                             else ''
                        end as 'InfoTypeDescription', 
                        stringOpt.code as 'StringOptionCode', 
                        case when p_language = 'F' then stringOpt.frenchDescription
                             when p_language = 'E' then stringOpt.englishDescription    
                             else ''
                        end as 'StringOptionDescription'
                                            FROM InfoType infoType
                                            JOIN StringOptionValue stringOptVal ON infoType.code = p_infoTypeCode AND infoType.code = stringOptVal.codeInfoType
                                            JOIN StringOption stringOpt ON stringOptVal.codeStringOption = stringOpt.code;
DECLARE CONTINUE HANDLER FOR NOT FOUND SET v_noMoreRow = 0;

SET v_noMoreRow = 1;

OPEN cur_stringOptions;
LOOPROWS: LOOP

    IF v_noMoreRow = 0 THEN
        CLOSE cur_stringOptions;
        LEAVE LOOPROWS;
    END IF;

    FETCH NEXT FROM cur_stringOptions INTO v_infotype_code, v_infotype_description, v_stringopt_code, v_stringopt_description;
    SELECT v_infotype_code, v_infotype_description, v_stringopt_code, v_stringopt_description;

END LOOP;

END$$

DELIMITER ;

當我通過 PHPMyAdmin 在 MySQL 下編譯我的存儲過程時，沒問題。 但是當我這樣調用我的存儲過程時：

call GetStringOptionList('EYESCOLOR', 'F')

當我嘗試在 http://localhost... 上通過 PHPMyAdmin 執行存儲過程時出現以下錯誤：

Missing expression (near "ON" at position 25)
#2014 - Commands out of sync; you can't run this command now

我已經在控制台模式下嘗試過程序“mysql”。 當我執行“call GetStringOptionList("EYESCOLOR", "F")”時，我得到一個帶有箭頭“->”的空行。 我不知道這是什么意思。

為什么 ？ 你有解決方案嗎 ？

我減少了別名的名稱長度並刪除了“OR REPLACE”（見下文），但我總是出現相同的錯誤：
