大神们求解MariaDb创建过程哪儿错了?

[comfan_china]

下面是我过程里面的代码

BEGIN
		select @biaos:=`data` from classm_t_propreties where
		`key`='user.idgeneration.pp';
	DELETE FROM classm_t_loginnablesafe where 
		classm_t_loginnablesafe.loginnableid=@urId;
	if left(@urId,4)=(@biaos) then 
		DELETE FROM classm_t_classpeople where classm_t_classpeople.id=@urId;
		ELSE DELETE FROM classm_t_adminusr where classm_t_adminusr.id=@urId;
	end IF
END;

过程创建使用Navicat Premium工具

没有错误提示吗？
