mysql装配后初始密码的设置
mysql安装后初始密码的设置 在windows操作系统下,下载mysql5.6.10,安装后有两个默认的root账户,root账户其实等同于空账户即: shell mysql 等同于; shell mysql -u root 这两者都能登录上mysql。 初始密码为空,接下来就要设置初始密码 (1) SET PASSWOR
mysql安装后初始密码的设置在windows操作系统下,下载mysql5.6.10,安装后有两个默认的root账户,root账户其实等同于空账户即:
shell >mysql
等同于;
shell >mysql -u root
这两者都能登录上mysql。
初始密码为空,接下来就要设置初始密码
(1)
SET PASSWORD FOR ‘’@‘localhost’ = PASSWORD('youpass');或者
SET PASSWORD FOR ‘root’@localhost = PASSWORD('youpass');
其中的第一个引号内表示 的是用户名,可见起初的用户名 ‘root' = ''.
@ 后面的表示的是本地还是联网的,localhost表示本地,%表示联网。
关于引号’‘。我尝试过去掉’‘没有任何问题。网上说的大概是为了防止字符串保证一些特殊的字符串,比如把空格包含进去。
例如我在用户登录时候 可以是这个样子:
mysql -u root -p
*******
或者:
mysql -u 'root' -p
*******

MySQL is an open source relational database management system. 1) Create database and tables: Use the CREATEDATABASE and CREATETABLE commands. 2) Basic operations: INSERT, UPDATE, DELETE and SELECT. 3) Advanced operations: JOIN, subquery and transaction processing. 4) Debugging skills: Check syntax, data type and permissions. 5) Optimization suggestions: Use indexes, avoid SELECT* and use transactions.

You can open phpMyAdmin through the following steps: 1. Log in to the website control panel; 2. Find and click the phpMyAdmin icon; 3. Enter MySQL credentials; 4. Click "Login".

MySQL is an open source relational database management system, mainly used to store and retrieve data quickly and reliably. Its working principle includes client requests, query resolution, execution of queries and return results. Examples of usage include creating tables, inserting and querying data, and advanced features such as JOIN operations. Common errors involve SQL syntax, data types, and permissions, and optimization suggestions include the use of indexes, optimized queries, and partitioning of tables.

MySQL and SQL are essential skills for developers. 1.MySQL is an open source relational database management system, and SQL is the standard language used to manage and operate databases. 2.MySQL supports multiple storage engines through efficient data storage and retrieval functions, and SQL completes complex data operations through simple statements. 3. Examples of usage include basic queries and advanced queries, such as filtering and sorting by condition. 4. Common errors include syntax errors and performance issues, which can be optimized by checking SQL statements and using EXPLAIN commands. 5. Performance optimization techniques include using indexes, avoiding full table scanning, optimizing JOIN operations and improving code readability.

Redis uses a single threaded architecture to provide high performance, simplicity, and consistency. It utilizes I/O multiplexing, event loops, non-blocking I/O, and shared memory to improve concurrency, but with limitations of concurrency limitations, single point of failure, and unsuitable for write-intensive workloads.

Recovering deleted rows directly from the database is usually impossible unless there is a backup or transaction rollback mechanism. Key point: Transaction rollback: Execute ROLLBACK before the transaction is committed to recover data. Backup: Regular backup of the database can be used to quickly restore data. Database snapshot: You can create a read-only copy of the database and restore the data after the data is deleted accidentally. Use DELETE statement with caution: Check the conditions carefully to avoid accidentally deleting data. Use the WHERE clause: explicitly specify the data to be deleted. Use the test environment: Test before performing a DELETE operation.

MySQL is chosen for its performance, reliability, ease of use, and community support. 1.MySQL provides efficient data storage and retrieval functions, supporting multiple data types and advanced query operations. 2. Adopt client-server architecture and multiple storage engines to support transaction and query optimization. 3. Easy to use, supports a variety of operating systems and programming languages. 4. Have strong community support and provide rich resources and solutions.

Building an SQL database involves 10 steps: selecting DBMS; installing DBMS; creating a database; creating a table; inserting data; retrieving data; updating data; deleting data; managing users; backing up the database.
