之前分享过多次Mysql主题,今天继续分享mysql命令行入门 1. 那么多mysql客户端工具,为何要分享命令行操作? -快捷、简单、方便 -在没有客户端的情况下怎么办 -如果是mysql未开启第三方访问,客户端就是白瞎 2. 如何通过命令行进入mysql --Start--
[root@localhost~]# mysql -u root -p #老徐注释:输入左侧命令,回车 root是用户名
Enter password: #老徐注释:输入密码

3. 如何查看数据库信息 --Start----End-- 4. 使用某个数据库 查看当天库下有哪些表 --Start--mysql> show databases; #老徐注释:输入左侧命令,回车
+--------------------+

| information_schema |
| mysql |
| performance_schema |

mysql> #老徐注释:如上就是显示当前存在的数据库
--End-- 5. 剩下就是很简单的增删改查了 如: select * from xx where xx = xx update xx set xx = xx where xx delete insert 等等 具体sql增删改查知识,自行百度,或者买个数据库书好好看mysql> use mysql #老徐注释:左侧,use 表名,使用某个表
Database changed
mysql> show tables; #老徐注释:显示当前数据库下的所有表名
