问题 I ran a massive SQL query that I don't want to run again and saved the results as a csv. I am doing some processing in a C# console app that adds each record to a storage table. Unfortunately, I messed up and did not remove ','s from the results, and there are some objects serialized in JSON in this data which contain ','. I am already looping through all this data, and so that my columns correctly line up I would just like to temporarily convert ',' to say ';', but only if it is between

打开blog发现从上一篇文章发布的时间到现在已经近1个月了，时间的概念在这一刻变得这么可怕。。。为自己找点理由吧，这么久没更新是因为。。。好吧，真的不想找类似工作忙、情绪糟糕、没什么可写的诸如此类的理由。我果断检讨---我懒了。猛然又意识到很多blog社区，包括这里--cnblog对blog的称呼很有意思--”随笔“。记得自己早先开始写BLOG的时候注意到这点时很不满，心说自己还想在这篇BOLG里大说一通呢，里面有很多”牛逼“的心得、”独家“的技术要点还要加上点“幽默”的笔触，怎么他们就这么不当回事呢？居然把我要发表的“大作”一笑带过的感觉，偏称之为“随笔”。如今google了一下-所谓“随笔”即是随手笔录，抒情、叙事或评论不拘，篇幅短小。我想放在如今的BOLG里，“随笔”的意境可能还要更随便些，可大可小，可糙可精，可以是规定自己每天都写，可以是随心所欲有感才而发。“随笔”这词把BLOG的精髓诠释的凌厉精致。SO，我自己写BLOG也会更加“随笔”，提醒自己千千万万不要出现一个月没来写东西的情况了。虽然不会强制自己的频率，但话说一个月都无感来发岂不是人生过得很失败-_-!。。结束自己的话唠吧。今天总结下最近写游戏服务器端设计数据库的一点心得---再次感慨数据库设计真是一门科学啊，什么技术都是越深入越探不到底。 MySQL 的 replace into 语句：
