Unknown Table 'Column_Statistics' In Information_Schema (1109) (Resolved)

This error message is indicating that there is a problem with the MySQL database you are trying to access. Specifically, it is saying that there is an unknown table called 'column_statistics' in the information_schema database.

There are a few potential causes for this error:

1. The table 'column_statistics' does not exist in the information_schema database. This could be due to the table being deleted or renamed.
2. The user does not have the necessary permissions to access the 'column_statistics' table in the information_schema database.
3. The MySQL server is not running or is not configured properly.

To fix this error, you will need to determine the root cause and take the appropriate action.

1. If the table does not exist, you will need to either create a new table with the same name, or update any queries or scripts that reference the missing table.
2. If the user does not have the necessary permissions, you will need to grant the user the appropriate privileges or to use a user that have the necessary privileges.
3. If the MySQL server is not running or is not configured properly, you will need to start the server and check the configuration to ensure it is set up correctly.
4. In some cases, if the error message is related to a specific plugin or application, you might need to check the documentation or troubleshoot the plugin or application to determine if there is a known issue or if there is an update that fixes the problem.
5. Another cause could be a missing or corrupted table in the information_schema database. You can check if all the tables in the information_schema are present and in good condition by running a repair command on the information_schema database.
6. There may be also a problem with the MySQL installation itself. Reinstalling or updating the MySQL version may resolve the issue.

It's important to note that making changes to the information_schema database can be risky and should be done with caution. Before making any changes, make sure to backup your data, and test the changes in a non-production environment.

It is also recommended to consult with a database administrator or developer to ensure that the changes made are appropriate and will not cause further issues.

What is the information_schema database?

The information_schema database is a set of read-only tables that provide information about all of the other databases that the MySQL server maintains. It's a virtual database, not a physical one. This means that the information_schema doesn't contain data, but rather it provides a window into the data stored in other databases.
