Depending on the cause, the fix may involve running a query, changing a configuration setting, or other action. For example, if the issue is caused by a missing index, the following query can be used to create the index:CREATE INDEX index_name ON table_name (column_name);
3. After the issue is fixed, it is important to verify that the fix was successful. This can be done by running the same command used in step 1:SHOW ENGINE INNODB STATUS;
