1:问题故障描述 因为在linux下开发,所以修改mysql字段的时,用的phpmyadmin来直接修改生成修改后的sql,然后复制进word(libreoffice)后提交到项目管理系统, 同事发到项目管理系统后不能运行.于是有了这篇文章. 2:首先新建表 [delphi] CREATE TABLE IF NOT EXISTS `nns_ad_log_count` ( `nns_id` char(32) CHARACTER SET utf8 COLLATE utf8_unicode_ci NOT NULL COMMENT '广告ID', `nns_access_type` tinyint(4) NOT NULL COMMENT '0:5m 1:1h 2:24h=1d', `nns_access_day` date NOT NULL COMMENT '哪一天的', `nns_access_index` int(11) NOT NULL COMMENT '间隔数,5m 1h 1d=24h', `nns_access_count` int(11) NOT NULL ) ENGINE=InnoDb DEFAULT CHARSET=utf8; 这步是OK的.接着因为项目扩展,增加了1个字段,同时需要修改一个表的字段名和另外几个表的default 默认值和类型 [sql] ALTER TABLE `nns_ad_log_count` CHANGE `nns_id` `nns_ad_id` CHAR( 32 ) CHARACTER SET utf8 COLLATE utf8_unicode_ci NOT NULL COMMENT '广告ID'; 上面这步,是用的phpmyadmin添加的字段后生成的一句sql, 看上去是没问题的,复制到word里面,再拿到mysql里面执行一下
报错了.百思不得其解,为什么会这样子呢? 3: 错误分析.生成的sql,是干净的, 途中同事只粘贴进了word. 于是手写了一遍这个sql,并且在mysql里面运行 (为了测试,我复制了上面的表结构,并且新建了一个测试的表`nns_ad_log_count1`)
运行正常同事只复制了一次,粘贴到了word (libreoffice) 我重复一下他的动作
"1. 先用浏览器打开phpmyadmin,在phpmyadmin里面直接修改一次,产生sql语句""2. 在phpmyadmin 里面,复制生成的sql到系统的剪贴板缓存""3. 粘贴进word""4. 重复其他的修改操作,重复1,2,3步""5. 把整个word发送给我""6. 我把word里面的sql拷贝出来,运行 ""7. 报错"打开word,发现sql的语句的空格在word里面高亮了
但是在mysql里面直接执行并没能看见这个东西,在phpmyadmin里面执行上面的sql
空格显示出来了,原来是这个Â 自此问题已经明了.sql语句在复制到word后给污染了. 但是为什么会这样子污染呢? 发现只有word粘贴进去后,会把utf8下的空格换成Â 这个应该是linux下的office工具的问题, 这里就不再陈述了 4: 后记, 在linux下做开发提交的sql语句,建议复制到vim里面查看详细的格式,或者更简单的,复制出来后,在浏览器地址栏粘贴一次再复制进word来提交文档.以免sql变脏出错.

The string data types in MySQL include CHAR, VARCHAR, BINARY, VARBINARY, BLOB, and TEXT. The collations determine the comparison and sorting of strings. 1.CHAR is suitable for fixed-length strings, VARCHAR is suitable for variable-length strings. 2.BINARY and VARBINARY are used for binary data, and BLOB and TEXT are used for large object data. 3. Sorting rules such as utf8mb4_unicode_ci ignores upper and lower case and is suitable for user names; utf8mb4_bin is case sensitive and is suitable for fields that require precise comparison.

The best MySQLVARCHAR column length selection should be based on data analysis, consider future growth, evaluate performance impacts, and character set requirements. 1) Analyze the data to determine typical lengths; 2) Reserve future expansion space; 3) Pay attention to the impact of large lengths on performance; 4) Consider the impact of character sets on storage. Through these steps, the efficiency and scalability of the database can be optimized.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
