Oct 09, 2025 am 05:17 AMTo compress or repair a database using Navicat, follow these steps. For SQLite, compression can be achieved by enabling "Vacuum" when exporting or directly executing the VACUUM command; MySQL achieves similar effects through optimization. Methods to repair damaged databases or tables: 1. Find the target table in Navicat in MySQL and select "Repair Table"; 2. Run PRAGMAintegrity_check in SQLite to check for errors, and use VACUUM and PRAGMAreindex to try to repair it; 3. When seriously damaged, priority should be given to restoring from backup. Other suggestions include regular backups, using the InnoDB engine, regular optimization in the development environment, and setting up automatic maintenance.
Oct 09, 2025 am 01:59 AMIn Bash scripts, if is suitable for simple logical judgments, and case is suitable for multi-value matching. 1.
