Mysql继续处理程序语法错误

Question

我无法看到这种语法有什么问题请帮忙！我试着从这里查找语法 http://dev.mysql.com/doc/refman/5.5/en/declare-handler.html

   DELIMITER $$
    DROP PROCEDURE IF EXISTS `load_dimensions`$$
    CREATE PROCEDURE `load_dimensions`( )
    BEGIN

     -- Declare variables to hold diagnostics area information
      DECLARE code CHAR(5) DEFAULT '00000';
      DECLARE msg TEXT;
      DECLARE rows INT;
      DECLARE result varchar(300);
      -- Declare exception handler for failed insert
      DECLARE CONTINUE HANDLER FOR SQLEXCEPTION
      BEGIN
           GET DIAGNOSTICS CONDITION 1 code = RETURNED_SQLSTATE, msg = MESSAGE_TEXT;
      END;

    INSERT  dimtable(col)
    SELECT  col FROM extract;

    IF code = '00000' THEN
        GET DIAGNOSTICS rows = ROW_COUNT;
        SET result = CONCAT('succeeded, row count = ',rows);
        INSERT INTO etl_log (result)
        SELECT CONCAT('Error',state,': ',msg);
      ELSE
        SET result = CONCAT('failed, error = ',code,', message = ',msg);
        INSERT INTO etl_log (result)
        SELECT CONCAT('Error',state,': ',msg);
      END IF;

    END $$

来自MySQL 5.5 reference pages

  

在MySQL 5.6之前不支持GET DIAGNOSTICS语句。
