关于mysql trigger调用udf问题

一个文件student.sql里内容
use yy;

DELIMITER |

DROP TRIGGER IF EXISTS student_trigger;
CREATE TRIGGER student_trigger
AFTER INSERT ON student
FOR EACH ROW BEGIN
SET @tt_json = (SELECT json_object(id,name) FROM student WHERE id = NEW.id LIMIT 1);
SET @tt_con = (SELECT redis_connect("10.1.60.125",6379));
SET @tt_resu = (SELECT redis_pipe(CONCAT("SET ",NEW.id," ",@tt_json,"\r\n")));

END |


DELIMITER ;


另一个文件student_new.sql内容


use yy;

DELIMITER |

DROP TRIGGER IF EXISTS student_update_trigger;
CREATE TRIGGER student_update_trigger AFTER UPDATE ON student;
FOR EACH ROW BEGIN
SET @tt_json = (SELECT json_object(id,name) FROM student WHERE id = NEW.id LIMIT 1);
SET @tt_con = (SELECT redis_connect("10.1.60.125",6379));
SET @tt_resu = (SELECT redis_pipe(CONCAT("SET ",NEW.id," ",@tt_json,"\r\n")));
END |

DELIMITER;



导入student_new.sql成功，导入student_new.sql提示：
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 ';
FOR EACH ROW BEGIN
SET @tt_json = (SELECT json_object(id,name) FROM studen' at line 1


请大家帮忙看下，两个触发器操作是一样的，为什么一个成功一个不成功，看了n久都没看出问题。
