mysqldump throws: Unknown table 'COLUMN_STATISTICS' in information_schema (1109)

Solution 1:

This is due to a new flag that is enabled by default in mysqldump 8. You can disable it by adding --column-statistics=0. The command will be something like:

mysqldump --column-statistics=0 --host=<server> --user=<user> --password=<password> 

Check this link for more information. To disable column statistics by default, you can add

[mysqldump]
column-statistics=0

to a MySQL config file, such as /etc/my.cnf or ~/.my.cnf.

Solution 2:

For those using MySQL Workbench, there is an "Advanced Options" button on the Data Export screen. The option "Use Column Statistics" can be disabled by setting to 0.

I have not confirmed, but the following information has been suggested to also be true: In Version 8.0.14 it's missing. In Version 8.0.16 it's doing this by default.


Solution 3:

I spent the whole day looking for a solution, and singed up here just to share mine.

Yes, probably this error is due to versions difference.

Just download the MySQL 5.7 ZIP Archive from here: https://dev.mysql.com/downloads/mysql/ and unzip it, then use the mysqldump.exe file from there.

If you are using MySQL Workbench, you will need to set a path to the mysqldump Tool you downloaded by going to Edit -> Preferences -> Administration (from left hand pane).

Hope this helps.

Solution 5:

To make this answer easier, you can rename mysqldump, make a shell script in its place and call the renamed mysqldump with the --column-statistics=0 argument. Eg:

Rename mysqldump:

mv /usr/local/bin/mysqldump /usr/local/bin/_mysqldump

Save the following shell script in its place:

#!/bin/sh

_mysqldump --column-statistics=0 [email protected]
