You can change a column's name, type, length or default value in phpMyAdmin.

Steps

  1. Export the table first.
  2. Open phpMyAdmin (in cPanel: Databases › phpMyAdmin) and click the database in the left panel.
  3. Click the table and open the Structure tab.
  4. Click Change next to the column.
  5. Edit the settings and click Save.

Note: Changing a type can cut data, for example shortening a VARCHAR trims longer values. Renaming a column breaks application code that uses the old name.
