Why UNIQUE KEY? Wouldn't PRIMARY KEY be better?
CREATE TABLE dbaliases (
alias_username varchar(64) default '' NOT NULL,
alias_domain varchar(128) default '' NOT NULL,
username varchar(64) default '' NOT NULL,
domain varchar(128) default '' NOT NULL,
UNIQUE KEY alias_key (alias_username,alias_domain),
INDEX alias_user (username, domain)
);
