phpMyAdmin is a versatile tool enabling users to modify, alter, and perform various functions on MySQL and MariaDB databases. It is accessible on cPanel, Plesk, and DirectAdmin platforms.
To Modify Table Columns in phpMyAdmin:
-
Log in to your control panel account (cPanel, DirectAdmin, or Plesk).
-
Navigate to and select phpMyAdmin.
-
The phpMyAdmin window will open. Choose a database from the list on the left side of your screen.
4. A list of tables will be displayed. Click on the '+' icon next to the table whose columns you wish to modify.
5. Click on the '+' icon next to "Columns" to reveal the list of columns within the table.
6. A panel allowing you to input and modify column attributes will appear. You can edit the column’s name, field length (character limit), default value, and more.
Note: Modifying specific aspects of table columns may lead to data loss or alteration. For instance, reducing the field length from 20 characters to 15 characters will truncate all data in that column to 15 characters.
After completing all modifications, click on Save.
phpMyAdmin will implement the changes, updating the table accordingly.
