个人git链接和git学习心得总结 个人git链接： https://github.com/lvcaixia 1、Git中的文件不是增量保存的 而是每个都存一份(原因：硬盘已经不是制约程序的因素) 2、Git采用的算法是SHA1 3、MD5跟SHA1已经被王小云在04、05年破解 4、作者：linux之父 Linus Torvalds 5、安装Git Bash （命令行中用到的是linux中的命令） 6、ls -la 显示隐藏文件 (windows or linux 目录前面加个.默认是隐藏文件) 7、使用git init 初始化(该文件夹下面会生成一个.Git的隐藏目录) 8、配置git 2 git config --global user.name 'liyang' git config --global user.email 'liyangfd@163.com' cd （到默认目录） pwd (显示当前目录) ls -la 查看目录列表 注意.gitconfig cat .gitconfig 这个会覆盖全局的 切换回aaa目录 cat .git/config git config user.name 'liyang' git config user.email 'liyangfd@163.com' 9、Git:Three Area Repository 仓库 默认.git

MySQL 数据类型

由 主宰稳场 提交于 2019-12-19 00:20:23
MySQL 数据类型 MySQL中定义数据字段的类型对你数据库的优化是非常重要的。 MySQL支持多种类型，大致可以分为三类：数值、日期/时间和字符串(字符)类型。 数值类型 MySQL支持所有标准SQL数值数据类型。 这些类型包括严格数值数据类型(INTEGER、SMALLINT、DECIMAL和NUMERIC)，以及近似数值数据类型(FLOAT、REAL和DOUBLE PRECISION)。 关键字INT是INTEGER的同义词，关键字DEC是DECIMAL的同义词。 BIT数据类型保存位字段值，并且支持MyISAM、MEMORY、InnoDB和BDB表。 作为SQL标准的扩展，MySQL也支持整数类型TINYINT、MEDIUMINT和BIGINT。下面的表显示了需要的每个整数类型的存储和范围。 **类型** **大小** **范围（有符号）** **范围（无符号）** **用途** TINYINT 1 字节 (-128，127) (0，255) 小整数值 SMALLINT 2 字节 (-32 768，32 767) (0，65 535) 大整数值 MEDIUMINT 3 字节 (-8 388 608，8 388 607) (0，16 777 215) 大整数值 INT或INTEGER 4 字节 (-2 147 483 648，2 147 483 647) (0，4 294
