Is there any way to make a UNIQUE index case insensitive in Mysql 5.1.x ?

Question

If so - What must change in this table ?

CREATE TABLE  contestants 
( 
  idContestants  int(10) unsigned NOT NULL AUTO_INCREMENT,
  idEvent        int(10) un         


        

Answer 1

This worked for me in Mysql 5.5

ALTER TABLE `contestants` MODIFY
`ContestantName` VARCHAR(50) 
CHARACTER SET latin1
COLLATE latin1_bin;
