I'm guessing you mean 'into MySQL'
\ I see a column indicating that the field is unique but do not see how to change it\
I'm guessing again - You mean in phpMyAdmin???
I will say before you change anything, its likely that any fields/colums that are marked as 'unique' are part of an index - and - if you change that you may break the script/application.
The last is just based on experience. If its your own code - do what you will.http://www.phpfreaks.com/forums/index.p ... c=259326.0
