Does mysql optimize lock tables
Apr 08, 2025 pm 01:51 PM
MySQL uses shared locks and exclusive locks to manage concurrency, providing three lock types: table locks, row locks and page locks. Row locks can improve concurrency, and use the FOR UPDATE statement to add exclusive locks to rows. Pessimistic locks assume conflicts, and optimistic locks judge the data through the version number. Common lock table problems manifest as slow querying, use the SHOW PROCESSLIST command to view the queries held by the lock. Optimization measures include selecting appropriate indexes, reducing transaction scope, batch operations, and optimizing SQL statements.
Do mysql need to pay
Apr 08, 2025 pm 05:36 PM
MySQL has a free community version and a paid enterprise version. The community version can be used and modified for free, but the support is limited and is suitable for applications with low stability requirements and strong technical capabilities. The Enterprise Edition provides comprehensive commercial support for applications that require a stable, reliable, high-performance database and willing to pay for support. Factors considered when choosing a version include application criticality, budgeting, and technical skills. There is no perfect option, only the most suitable option, and you need to choose carefully according to the specific situation.

How to recover data after SQL deletes rows
Apr 09, 2025 pm 12:21 PM
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.
