Hi there I am using MySQL in "phpmyadmin.eu.ionos.host" and want to change a column to 'UNIQUE' as I don't want to accidentally fill the table with repeat data using an erroneous php loop and each image must be unique. The table is: 2 Image char(200) utf8_unicode_ci SQL won't let me change the column to 'UNIQUE' as it says that there is a duplicate column 'Image'. The phpmyadmin SQL seems to be trying to add another column, which is what I dont want. 1and1 have very recently changed their software and there seem to be a lot of gremlins in it. Any comments??
