mySQL (phpMyAdmin) error : This table does not contain a unique column

If you face this error in phpMyAdmin and you can't change/edit the table fields.

If you sure you got error like this : 

"This table does not contain a unique column. Grid edit, checkbox, Edit, Copy and Delete features are not available."

 

So please execute next SQL query:

ALTER TABLE [tablename] add newid INT UNSIGNED NOT NULL AUTO_INCREMENT PRIMARY KEY FIRST;

You can execute the query from GUI of phpMyAdmin or from SSH CLI using mysql command first.
