Mysql：診断条件を返すヌル

Question

私は以下のmysqlストアドプロシージャを書いています。

CREATE DEFINER=`clocery`@`%` PROCEDURE `ADMIN_ADD_NEW_USER`(IN `IN_FIRST_NAME` varchar(50),IN `IN_LAST_NAME` varchar(50),IN `IN_USER_NAME` varchar(50), IN `IN_EMAIL` varchar(50),IN `IN_PASSWORD` varchar(80),IN `IN_ROLE` varchar(20),IN `IN_CREATED_BY` INT,OUT `OUT_STATUS` char(1),OUT `OUT_MESSAGE` varchar(200)) 
BEGIN 
    DECLARE logged_in_user_role_id INT; 
    DECLARE to_be_created_user_role_id INT; 
    DECLARE user_who_created_logged_in_user INT; 
    DECLARE matching_row_count_user_name INT; 
    DECLARE matching_row_count_user_e_mail INT; 

    DECLARE EXIT HANDLER FOR SQLEXCEPTION 
     BEGIN 
      ROLLBACK; 

      GET DIAGNOSTICS CONDITION 1 @sqlstate = RETURNED_SQLSTATE, @errno = MYSQL_ERRNO, @text = MESSAGE_TEXT; 

      CALL UTIL_LOG_ERROR('ADMIN_ADD_NEW_USER', @sqlState, @errno, @text); 

      SELECT 'N', UTIL_GET_ERROR_MESSAGE('some-error') 
       INTO OUT_STATUS, OUT_MESSAGE; 

    END; 

    /** 
     * If passed user_id is NULL. 
     */ 
    IF IN_CREATED_BY = NULL THEN 
     SELECT 'N', UTIL_GET_ERROR_MESSAGE('some-error') 
       INTO OUT_STATUS, OUT_MESSAGE; 

     CALL LOG_ERROR('ADD_NEW_USER', UTIL_GET_ERROR_MESSAGE('in-created-by-null')); 

    ELSE 
     SELECT U.ROLE_ID, U.CREATED_BY INTO logged_in_user_role_id, user_who_created_logged_in_user FROM USERS U WHERE U.ID = IN_CREATED_BY; 
     SELECT R.ID INTO to_be_created_user_role_id FROM ROLES R WHERE R.ROLE = IN_ROLE; 

     /** 
      * If user has provided invalid role. 
      */ 
     IF to_be_created_user_role_id = NULL THEN 
      SELECT 'N', UTIL_GET_ERROR_MESSAGE('in-valid-role-provided') INTO OUT_STATUS, OUT_MESSAGE; 
     ELSE 

      /** 
       * Lets' see if logged in user has more authority than the one we are trying to create. 
       */ 
       IF to_be_created_user_role_id <= logged_in_user_role_id THEN 
        SELECT 'N', UTIL_GET_ERROR_MESSAGE('permission-denied') INTO OUT_STATUS, OUT_MESSAGE; 
        CALL CREATE_NOTIFICATION_FOR_USER(user_who_created_logged_in_user, CONCAT(GET_USER_IDENTIFICATION(IN_CREATED_BY), 'tried to create an account of higher authority.')); 

       ELSE 

        /** 
         * Lets' check if user name already present in the database. 
         */ 
         SELECT COUNT(*) INTO matching_row_count_user_name FROM USERS U WHERE U.USER_NAME = IN_USER_NAME; 
         SELECT COUNT(*) INTO matching_row_count_user_e_mail FROM USERS U WHERE U.EMAIL = IN_EMAIL; 

         IF matching_row_count_user_name > 0 THEN 
          SELECT 'N', UTIL_GET_ERROR_MESSAGE('username-exists') INTO OUT_STATUS, OUT_MESSAGE; 

         ELSEIF matching_row_count_user_e_mail > 0 THEN 
          SELECT 'N', UTIL_GET_ERROR_MESSAGE('email-exists') INTO OUT_STATUS, OUT_MESSAGE; 

         ELSE 
          /** 
           * Now, we are good to insert. 
           */ 
           START TRANSACTION; 

           /** 
            * Inserting into credentials first. 
            */ 
            INSERT INTO CREDENTIALS(PASSWORD, LOCKED) VALUES (IN_PASSWORD, 'N'); 
            INSERT INTO USERS(F_NAME, L_NAME, USER_NAME, EMAIL, ROLE_ID, ACTIVE, DELETED, CREATED_BY, CREATED_DATE, CREDENTIAL_ID, LAST_ACTOR_ID) 
                VALUES(IN_FIRST_NAME, IN_LAST_NAME, IN_USER_NAME, IN_EMAIL, to_be_created_user_role_id, 'Y', 'N', IN_CREATED_BY, NOW(), LAST_INSERT_ID(), IN_CREATED_BY); 

            INSERT INTO HISTORY_USER_EVENTS(USER_ID, TEXT, TYPE) VALUES(LAST_INSERT_ID(), 
              CONCAT(UTIL_GET_USER_IDENTIFICATION(LAST_INSERT_ID()), '''s account was created by ', UTIL_GET_USER_IDENTIFICATION(IN_CREATED_BY), '.'), 
              UTIL_GET_EVENT_ID_FOR_ACCOUNT_ACTION('Created')); 

            INSERT INTO HISTORY_ADMIN_EVENTS(ADMIN_ID, TEXT, TYPE) VALUES(IN_CREATED_BY, 
              CONCAT(UTIL_GET_USER_IDENTIFICATION(IN_CREATED_BY), ' created account of ', UTIL_GET_USER_IDENTIFICATION(LAST_INSERT_ID()), ' with role ', IN_ROLE, '.'), 
              UTIL_GET_EVENT_ID_FOR_USER_ADDITION(IN_ROLE)); 

            SELECT 'Y', 'User created.' INTO OUT_STATUS, OUT_MESSAGE; 
            COMMIT; 
         END IF; 
       END IF; 


     END IF; 

    END IF; 

END 

ご覧のとおり、SQL例外が発生した場合に実行するハンドラを作成しました。このプロシージャは、多くの実行時エラーを生成するはずです。ただし、

RETURNED_SQL_STATEまたはMYSQL_ERROR_CODE OR MESSAGE_TEXTのいずれも取得できません。彼らはすべて値nullを得ます。

私は最初にロールバックを呼び出しているのですか？そして、それはどういうわけかすべての関連情報を駄目にするのですか？

あなたのスクリプトにDELIMITERを追加していないようです。
