问题表象:我的mysql中的 my.ini文件配置:
[csharp]#Path to installation directory. All paths are usually resolved relative to this. basedir="D:/software_builder/mysql/" #Path to the database root datadir="C:/ProgramData/MySQL/MySQL Server 5.5/Data/" 我在 datadir的路径下找到.err文件,查看错误原因 [html]121022 15:21:06 [Note] Plugin 'FEDERATED' is disabled. D:/software_builder/mysql/bin/mysqld: Table 'mysql.plugin' doesn't exist 121022 15:21:06 [ERROR] Can't open the mysql.plugin table.

把“mysql文件夹”拷贝到数据库的数据存放位置的data文件夹下(我的是:C:/ProgramData/MySQL/MySQL Server 5.5/data)
然后在服务里面启动mysql服务,结果:“I get it !”

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.

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.

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.

How to insert data into MySQL table? Connect to the database: Use mysqli to establish a connection to the database.

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.
