我目前在end if
和end loop
中遇到语法错误。我不知道为什么。请..请让我知道问题出在哪里。

尝试以下代码
CREATE PROCEDURE `oneTimeExcution`()
begin
DECLARE done INT DEFAULT FALSE;
DECLARE totalCount int(10) default 0;
DECLARE i INT DEFAULT 0;
DECLARE nowUnixTime int(10) unsigned default 0;
DECLARE id varchar(100) default null;
DECLARE cur CURSOR FOR SELECT deviceId FROM tb_sensor;
DECLARE CONTINUE HANDLER FOR NOT FOUND SET done = TRUE;
select (UNIX_TIMESTAMP()-31622400) into nowUnixTime;
select count(*) from tb_sensor into totalCount;
OPEN cur;
read_loop: loop
FETCH NEXT FROM cur INTO id;
IF done then
LEAVE read_loop;
END IF;
select 'success'; # condition comes here
END LOOP;
close cur;
end;
