1:错误日志大量错误

150602 14:40:02 [Warning] Unsafe statement written to the binary log using statement format since BINLOG_FORMAT = STATEMENT. INSERT... SELECT... ON DUPLICATE KEY UPDATE is unsafe because the order in which rows are retrieved by the SELECT determines which (if any) rows are updated. This order cannot be predicted and may differ on master and the slave. Statement:INSERT INTO tab_name
  

2:原因:

查了下原因,tab_name 这个表上有2个唯一键。则使用INSERT … ON DUPLICATE KEY UPDATE ,且当前数据库binlog_format是statement格式,这种sql语句就会报unsafe。
  

官方手册:

INSERT … ON DUPLICATE KEY UPDATE statements on tables with multiple primary or unique keys.When executed against a table that contains more than one primary or unique key, this statement is considered unsafe, being sensitive to the order in which the storage engine checks the keys, which is not deterministic, and on which the choice of rows updated by the MySQL Server depends.
  

解决方法:

把binlog_format设置为ROW或者STATEMENT或者修改SQL。

一般情况下就是mysql配置问题,大家可以参考这篇文章:https://www.jb51.net/article/84357.htm

P70系列延期,华为新旗舰将在下月发布

3月20日消息,近期博主@数码闲聊站 透露,原定三月份发布的华为新旗舰P70系列延期发布,预计4月份上市。

而博主@定焦数码 爆料,华为的P70系列在定位上已经超过了Mate60,成为了重要的旗舰系列之一。它肩负着重返影像领域顶尖的使命。那么这次P70会带来哪些令人惊艳的创新呢?

根据目前爆料的消息来看,华为P70系列将推出三个版本,其中P70和P70 Pro采用了三角形的摄像头模组设计,而P70 Art则采用了与上一代P60 Art相似的不规则形状设计。这样的外观是否好看见仁见智,但辨识度绝对拉满。
