请教一个问题
比如说建立了一个会员号表 id cardsn(会员号) uid cardsn是连续的像 031001 ,031002 现在有这样一个功能点击一个按钮增加5条记录且是连续的那么每次就要获取最新的会员号然后以此为基准连续生成5个号插入数据库问题就是如果多个用户同时操作这个表那么每次获得的最新一条记录用来连续就不准确了请教一下大家这个问题应该怎么解决

回复讨论(解决方案)

你可以开启事务。

如果5个用户同时对表操作，总有个先后的，你可以参考mysql事务处理，当你用户操作表的时候，会把表锁住，等操作完，其他用户才会继续操作。
如果并发很大，建议通过memcache队列的形式处理，缓解数据库表的压力。

使用队列形式处理

其它的很多操作都会用到这个表把表锁住会不会影响其它的操作

使用队列形式处理

能不能给具体说一下思路

使用事?
先?表，?理完再解除?定。

谢谢结贴给分

能否在问一个问题我的数据库现在的表都是MyISAM 类型如果使用锁定表在解锁的形式那其它的操作在用到用到这个表时会不会受到影响比如说锁定表时执行的是插入操作，其它又有一个操作要查询这个表那查询这个操作会受到影响吗？

锁表就是将原来并行的操作变成了串行操作
当然要影响性能的

斑竹再请教一个问题比如说锁表的时候目的是向这个表插入5个记录其它的另一个操作比如说注册也会向这个表插入数据那么可能会出现插入失败对吧

使用了表锁就产生了排队，但不会引起插入失败

谢谢斑竹的热心回答

谢谢大家的热心回答
