事务隔离级别测试

查看当前的mysql隔离级别

select @@tx_isolation

 设置数据库的隔离级别为read uncommitted

set session transaction isolation level read uncommitted

注意:隔离级别是和事务相关的,需要先启动事务,才有隔离级别

测试脏读:

 改变隔离级别再测试

测试不可重复读:

测试隔离级别为可重复读

可串行化:加锁的意思,如果有一张表正在被操作并且没有提交,会卡住不会操作

《事务隔离级别测试》有4个想法
  1. With havin so much content do you ever run into any problems of plagorism or copyright violation? My website has a lot of exclusive
    content I’ve either written myself or outsourced but it seems a lot of
    it is popping it up all over the internet without my permission. Do you know any solutions to
    help stop content from being stolen? I’d genuinely appreciate it.
    I saw similar here: Sklep internetowy

  2. Good day! Do you know if they make any plugins to assist with Search Engine Optimization? I’m trying to get my website
    to rank for some targeted keywords but I’m not
    seeing very good success. If you know of any please share.

    Thank you! I saw similar text here: GSA Verified List
