由 旧街凉风 提交于 2021-02-08 15:05:18
问题 I'm using Spring boot and I can't store emojis in database. I don't have access to my.cnf file. What I've done so far is: ALTER DATABASE name CHARACTER SET = utf8mb4 COLLATE = utf8mb4_unicode_ci; For each table: ALTER TABLE table CONVERT TO CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci; For each column: ALTER TABLE table CHANGE column column VARCHAR(190) CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci; In application.properties file I'm using this: spring.datasource.url = jdbc:mysql:/

步骤： 1、 首先在安装的mysql目录下创建my.ini文件 （深坑）注意：my.ini必须保存为ANSI格式！！！ 可以先创建一个my.txt的文件，然后另存为ANSI格式的文件！ my.ini内容如下： [ client ] port = 3306 default - character - set = utf8mb4 [ mysqld ] #修改成你自己的mysql路径 basedir = C:\\Software - D\\MySQL\\mysql - 8.0 . 18 - winx64 port = 3306 #服务端使用的字符集默认为8比特编码的latin1字符集 character - set - server = utf8mb4 #创建新表时将使用的默认存储引擎 default - storage - engine = INNODB [ mysql ] default - character - set = utf8mb4 2、打我的电脑C:\Windows\System32\cmd.exe，右击cmd选择以管理员身份运行 3、在dos命令窗口执行cd e:\workspace\mysql-5.6.24-win32\lib 转到bin目录下 执行删除命令 mysqld - remove 执行安装命令 mysql - install 执行初始化命令 mysqld -

来谈谈写作这件事

写作这件事,很多大佬都谈过,但我还是想从自己的角度去谈谈. 说到写作,我们就需要来说,我为什么要去写作,或者说,写作带给了我什么. 1 ,可以系统性的思考. 我觉得你肯定有这样的感受,就是一个知识点我明明懂了,可是给别人讲的时候,却总是讲不明白.知道为什么嘛?因为你只是以为你自己懂了,实际上你并没有懂. 而写作就相当于你在给别人讲,那么你为了写明白一个知识点,为了让别人读懂你这篇文章,你会怎么做? 就拿这篇文章来说,为了向别人说明写作的重要性,你会怎么展开?起码会从是什么,为什么,怎么做,这三点去展开说,对吧. 那么,当你这样去写的时候,你发现,我好像对是什么不太清楚,所以你就会去查资料;我为什么要去用这个呢,想不明白,再去查资料;我怎么用这个知识呢,再去查资料或者实践. 这样做一次两次三次...当你坚持这样写完 100 篇文章的时候,你的思考角度,思维模式,绝对和写作之前不一样. 2 ,构建影响力. 对于一个人来说,最重要的是什么?是有自己的「影响力」. 当你有自己的影响力时,你就能够在整个行业里面脱颖而出,从而能够有机会结识更加优秀的人. 但是影响力很轻松就能构建?只想说,别做梦了. 那么,我怎么构建影响力? 高质量的内容 一件事情,你一定要想清楚,就是你和我都互相不认识,那么我凭什么信任你,我凭什么受你的影响,对吧.靠的就是高质量的内容. 我写博客,特别是需要实操的内容

问题 startTimestamp < date_sub(curdate(), interval 1 hour) Will the (sub)query above return all records created within the hour? If not will someone please show me a correct one? The complete query may look as follows: select * from table where startTimestamp < date_sub(curdate(), interval 1 hour); 回答1: Rather than CURDATE() , use NOW() and use >= rather than < since you want timestamps to be greater than the timestamp from one hour ago. CURDATE() returns only the date portion, where NOW() returns
