用ini文件远程连接mysql_MySQL

用ini文件远程连接mysql 最近改写个东西,又重新写了写MySql的连接。为了便于灵活应用,用读取ini文件的方式读取mysql连接参数。 顺便学习了下ini文件。 ini格式。ini文件由很多节组成。 [cpp] [NETWORK]//节 host=*.*.*.*//host:键、IP:值 user=root pwd=//不写即为空 读取: [cpp] GetPrivateProfileString("NETWORK","host","",host.GetBuffer(MAX_PATH),MAX_PATH,strFileName); 参数列表依次为:节名,键名,lpdefault,键值,键值长度,ini文件路径lpDefault : 如果INI文件中没有前两个参数指定的字段名或键名,则将此值赋给变量.返回值:键值。 写:[cpp] WritePrivateProfileString("NETWORK","host","1.2.3.4",strFileName); 参数列表依次为:节名,键名,键值,ini文件路径返回值:Long,非零表示成功,零表示失败 文件路径: 1.INI文件的路径必须完整,文件名前面的各级目录必须存在,否则写入不成功,该函数返回 FALSE 值. 2.文件名的路径中必须为 // ,因为在VC++中, // 才表示一个 / . 3.也可将INI文件放在程序所在目录,此时 lpFileName 参数为: ".//student.ini".配置文件写好了,接着就是连接: [cpp] mysql_real_connect(&mydata,host,user,pwd,database,port,unix_socket,clientflag); //其中的参数即是读取文件获得的。 数据的连接晚上帖子一堆,不再重述。mysql的连接基类已写好。稍后上传到资源。 想要远程连接,还有一个很重要的步骤:设置服务器可以远程: 1、在控制台执行 mysql -u root -p mysql,系统提示输入数据库root用户的密码,输入完成后即进入mysql控制台,这个命令的第一个mysql是执行命令,第二个mysql是系统数据名称,不一样的。 2、在mysql控制台执行 GRANT ALL PRIVILEGES ON *.* TO ‘root'@'%' IDENTIFIED BY ‘MyPassword' WITH GRANT OPTION; 3、 mysql> FLUSH PRIVILEGES; //使修改立即生效 可能会出现10060无法连接的错误,这时要查看下是否防火墙禁用了3306端口。 bitsCN.com

Big data structure processing skills: Chunking: Break down the data set and process it in chunks to reduce memory consumption. Generator: Generate data items one by one without loading the entire data set, suitable for unlimited data sets. Streaming: Read files or query results line by line, suitable for large files or remote data. External storage: For very large data sets, store the data in a database or NoSQL.

Backing up and restoring a MySQL database in PHP can be achieved by following these steps: Back up the database: Use the mysqldump command to dump the database into a SQL file. Restore database: Use the mysql command to restore the database from SQL files.

MySQL query performance can be optimized by building indexes that reduce lookup time from linear complexity to logarithmic complexity. Use PreparedStatements to prevent SQL injection and improve query performance. Limit query results and reduce the amount of data processed by the server. Optimize join queries, including using appropriate join types, creating indexes, and considering using subqueries. Analyze queries to identify bottlenecks; use caching to reduce database load; optimize PHP code to minimize overhead.

How to insert data into MySQL table? Connect to the database: Use mysqli to establish a connection to the database. Prepare the SQL query: Write an INSERT statement to specify the columns and values to be inserted. Execute query: Use the query() method to execute the insertion query. If successful, a confirmation message will be output.

Creating a MySQL table using PHP requires the following steps: Connect to the database. Create the database if it does not exist. Select a database. Create table. Execute the query. Close the connection.

To use MySQL stored procedures in PHP: Use PDO or the MySQLi extension to connect to a MySQL database. Prepare the statement to call the stored procedure. Execute the stored procedure. Process the result set (if the stored procedure returns results). Close the database connection.

One of the major changes introduced in MySQL 8.4 (the latest LTS release as of 2024) is that the "MySQL Native Password" plugin is no longer enabled by default. Further, MySQL 9.0 removes this plugin completely. This change affects PHP and other app

Oracle database and MySQL are both databases based on the relational model, but Oracle is superior in terms of compatibility, scalability, data types and security; while MySQL focuses on speed and flexibility and is more suitable for small to medium-sized data sets. . ① Oracle provides a wide range of data types, ② provides advanced security features, ③ is suitable for enterprise-level applications; ① MySQL supports NoSQL data types, ② has fewer security measures, and ③ is suitable for small to medium-sized applications.
