Hi guys,

I have a table, the table name is account,
its have 2 fields : membersid, and categoryid



i want to change the categoryid field content, i run this in phpmyadmin :

update `account` set categoryid = replace (categoryid, '1' , '2');

but get this error message

#1062 - Duplicate entry '23933-27243-2' for key 'membersid'

- what should i do so i can change the field content? Please help.
I already tried changing the field TYPE, from INT, to BIGINT, like other person suggested, but still get that error message

- this is the screenshot from the field Structure

Assuming a MySql database going by the error code.

Your changes are creating a duplicate key in a table index
