  • mysql tutorial on subqueries vs joins
    mysql tutorial on subqueries vs joins
    The applicable scenarios of subquery and connection are different, and performance depends on the specific situation. 1. Subqueries are suitable for queries with clear logic and simple structure, especially in single-value matching or aggregation scenarios; 2. Connections are more suitable for scenarios where multiple rows of result matching or multiple table fields are obtained simultaneously, and are usually more efficient when processing large amounts of data; 3. In actual use, indexes, query structures and requirements should be combined, and execution plans should be analyzed through EXPLAIN to optimize performance.

  • How do MyISAM table locks vs InnoDB row locks affect an application?
    How do MyISAM table locks vs InnoDB row locks affect an application?
    MyISAM uses table locks, which are suitable for read-only or low-concurrency scenarios; InnoDB uses row locks, which are suitable for high-concurrency writing. 1.MyISAM write operation will lock the entire table, affecting concurrency performance; 2.InnoDB only locks the affected rows to improve concurrency processing capabilities; 3. If transactions or foreign key support is required, InnoDB must be used; 4. Select the appropriate engine based on the data volume and read and write frequency.

  • mysql access denied for user 'root'@'localhost' mac
    mysql access denied for user 'root'@'localhost' mac
    When you encounter MySQL login error, Accessdeniedforuser'root'@'localhost', first check whether the password is correct or try to reset the password: 1. Stop the MySQL service and skip the permission verification startup; 2. Enter MySQL to modify the root user password and restart the service. Secondly, confirm whether the wrong use of the -p parameter leads to forced entry of the password. If root does not set a password, you should log in directly. Then check the user permission configuration to ensure that 'root'@'localhost' exists and the permissions are correct, and manually create and authorize if necessary. Finally, confirm whether the MySQL service has been started. If it is not started, start the service to resolve the problem.

Adjust the my.ini configuration parameters, such as setting innodb_buffer_pool_size to 50%~70% of memory, increasing innodb_log_file_size to 256M or higher, setting max_connections reasonably, and deciding whether to enable query cache based on the version. 2. Use SSD to improve disk IO, separate data from log file storage paths, enable innodb_flush_method=O_DIRECT and turn off NTFS access time update. 3. Regularly execute ANALYZETABLE
