MySQL最基本的命令使用汇总_MySQL
一、连接MySQL(和PHP搭配之最佳组合)
格式: -h主机地址 -u用户名 -p用户密码
代码如下:
-h110.110.110.110 -uroot -pabcd123
(注:u与root可以不用加空格,其它也一样)
3、退出MySQL命令: exit (回车)。
二、修改密码
格式:admin -u用户名 -p旧密码 password 新密码
例1:给root加个密码ab12。首先在DOS下进入目录bin,然后键入以下MySQL命令:
代码如下:
admin -uroot -password ab12
注:因为开始时root没有密码,所以-p旧密码一项就可以省略了。
例2:再将root的密码改为djg345,命令:
代码如下:
admin -uroot -pab12 password djg345
三、增加新用户
(注意:和上面不同,下面的因为是MySQL环境中的命令,所以后面都带一个分号作为命令结束符)
代码如下:
grant select,insert,update,
delete on *.* to test1@\"%\" Identified by \"abc\";
但例1增加的用户是十分危险的,你想如某个人知道test1的密码,那么他就可以在internet上的任何一台电脑上登录你的MySQL数据库并对你的数据可以为所欲为了, 代码如下:
grant select,insert,update,
delete on mydb.* to test2@localhost identified by \"abc\";
如果你不想test2有密码,可以再打一个命令将密码消掉。
代码如下:
grant select,insert,update,delete on mydb
.* to test2@localhost identified by \"\";
以上叙述了登录、增加用户、密码更改等问题,希望对大家的学习有所帮助。

InnoDB's full-text search capabilities are very powerful, which can significantly improve database query efficiency and ability to process large amounts of text data. 1) InnoDB implements full-text search through inverted indexing, supporting basic and advanced search queries. 2) Use MATCH and AGAINST keywords to search, support Boolean mode and phrase search. 3) Optimization methods include using word segmentation technology, periodic rebuilding of indexes and adjusting cache size to improve performance and accuracy.

Full table scanning may be faster in MySQL than using indexes. Specific cases include: 1) the data volume is small; 2) when the query returns a large amount of data; 3) when the index column is not highly selective; 4) when the complex query. By analyzing query plans, optimizing indexes, avoiding over-index and regularly maintaining tables, you can make the best choices in practical applications.

The difference between clustered index and non-clustered index is: 1. Clustered index stores data rows in the index structure, which is suitable for querying by primary key and range. 2. The non-clustered index stores index key values and pointers to data rows, and is suitable for non-primary key column queries.
