mysql 存储过程（proceduce）查询一个表的结果插入另外一个表

DROP procedure record_timestamp_deal ;

##创建存储过程
create procedure record_timestamp_deal()

begin

declare tslogId varchar(50);
declare done int default 0;

# declare existence boolean ;

##从时间戳记录表中获取ID存入游标
declare cur cursor for select id from time_stamp_log;

##异常处理
declare continue handler for sqlstate ‘02000‘ set done = 1;

open cur;
    ##取出游标值至变量中
    fetch next from cur into tslogId;
    
repeat
    if not done then 
        #查询时间戳待记录id是否在时间戳待存证表
        if (select * from osv_timestamp_evi_prepare where timestampId = tslogId) is not null then
            ##不存在的记录写入待存证表
            insert into osv_timestamp_evi_prepare(timestampId,createTime) values(tslogId,now());
        end if;
    end if;

    ##重新抓取数据进入循环
    fetch next from cur into tslogId;

##结束循环
until done end repeat;

##关闭游标
close cur;

end ;

call record_timestamp_deal();
