The following articles mainly describe how to implement simple and practical MySQL database optimization methods, including how to regularly analyze and check tables and how to optimize tables on a regular basis, the following is a description of the specific solution. I hope it will help you in your future study.1. Regular analysis table and checklist The analysis table syntax is as follows:Copy codeThe Code is as follows: ANALYZE [LOCAL | NO_WRITE_T

This section only describes how to use internal locking of a table. For the checklist locking protocol, this process only checks the table and does not fix the table.

MySQL database standardization design (3) tip: it is a good idea to establish a database table maintenance specification to check the database table on a regular basis instead of waiting until the problem occurs. Taking into account the creation of a schedule for preventive maintenance to assist with automatic problems, you can take measures to correct: execute regular database backup and allow log updates. Schedule regular table checks. Check the table to reduce the number
