将MySQL安装完成之后还需要对其进行测试,判断MySQL是否安装成功,MySQL其可视化与我们之前使用过的SQLserver不同。MySQL其中测试方法有两种:一、使用MySQL命令进行测试;二、安装客户端对其进行连接测试。由于二种方法可视化强,操作简单,所以就不做详细的介绍;在这就主要介绍一下MySQL的测试命令。
第一步 在打开DOS窗口,输入命令1,进入目录 mysqlbin,如图:
第二步 输入命令:“mysql -u用户名 -p”,如图:
第三步 输入密码(之前设置的4位以上的密码)进入MySQL,如图:
第四步 输入命令:“use test”,如图:打开数据库库。
第五步 使用“show databases;”,如图:命令显示数据库列表。
另外,再补充些其他的MySQL基本命令:
1、修改密码
mysqladmin -u用户名 -p旧密码 password 新密码
例:将root的密码改1212为123456。
mysqladmin -uroot -p1212 password 123456
2、增加新用户
grant select on 数据库.* to 用户名@登录主机identified by “密码”
3.显示数据库列表。
show databases;
4.显示库中的数据表:
use mysql;
show tables;
5.显示数据表的结构:
describe 表名;
6.建库:
create database 库名;
7.建表:
use 库名;
create table 表名 (字段设定列表);
8.删库和删表:
drop database 库名;
drop table 表名;
9、将表中记录清空:
delete from 表名;
10.显示表中的记录:
select * from 表名;
11、显示最后一个执行的语句所产生的错误、警告和通知:
show warnings;
12.只显示最后一个执行语句所产生的错误:
show errors;

Mastering the method of adding MySQL users is crucial for database administrators and developers because it ensures the security and access control of the database. 1) Create a new user using the CREATEUSER command, 2) Assign permissions through the GRANT command, 3) Use FLUSHPRIVILEGES to ensure permissions take effect, 4) Regularly audit and clean user accounts to maintain performance and security.

Best practices for handling string data types and indexes in MySQL include: 1) Selecting the appropriate string type, such as CHAR for fixed length, VARCHAR for variable length, and TEXT for large text; 2) Be cautious in indexing, avoid over-indexing, and create indexes for common queries; 3) Use prefix indexes and full-text indexes to optimize long string searches; 4) Regularly monitor and optimize indexes to keep indexes small and efficient. Through these methods, we can balance read and write performance and improve database efficiency.

When selecting MySQL's BLOB and TEXT data types, BLOB is suitable for storing binary data, and TEXT is suitable for storing text data. 1) BLOB is suitable for binary data such as pictures and audio, 2) TEXT is suitable for text data such as articles and comments. When choosing, data properties and performance optimization must be considered.
