必須使用delimiter來分隔造成的功能手動

 DELIMITER $$ 
DROP FUNCTION IF EXISTS `CreateGroup` $$ 
CREATE FUNCTION CreateGroup(GroupName VARCHAR(50), GroupIcon TEXT, GroupDescription VARCHAR(130), GroupCreator INT) 
    RETURNS int(11) 
    DETERMINISTIC

    INSERT INTO groups (name, icon, description) VALUES (GroupName, GroupIcon, GroupDescription); 
    SET groupID = LAST_INSERT_ID(); 
    INSERT INTO group_members VALUES (groupID, GroupCreator); 
    RETURN groupID; 
END; 
DROP FUNCTION IF EXISTS `AddMessage` $$ 
CREATE FUNCTION AddMessage(r VARCHAR(255), s INT, t INT, m VARCHAR(255), creation DATETIME) 
    RETURNS int(11)

     SET lastID = LAST_INSERT_ID();
