How It Affects Your App
MySQL 1020 ER_CHECKREAD has a significant impact on an application. It indicates that the server was unable to read the file. This can cause the application to crash or malfunction, as it is unable to access the necessary data. It can also lead to data corruption, as the application may not be able to read the data correctly. In addition, it can cause the application to become unresponsive, as the server is unable to read the file.
How To Fix

3. Check the MySQL server status to see if the server is running. This can be done by running the following command:
mysql> SHOW GLOBAL STATUS;
4. Check the MySQL server process list to see if there are any processes that are running that could be causing the issue. This can be done by running the following command:
