CREATE TABLE `host_email` (

) ENGINE=MyISAM AUTO_INCREMENT=19682 DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci$$



insert into host_email (event_code_id,event_code_admins_id,user_id,host_email_name,host_email_first_name,host_email_last_name,host_email_email,host_email_type,host_email_member,nominate,course1,course2,course3,course4,additional_notes) select '87','72','11688','robert jones','robert','jones','email@email.com',4, '1', '', '1', '6', '3', '', 'almost vegitarian' from dual where not exists (select 1 from host_email where host_email_email = 'email@email.com' and event_code_id='87' and event_code_admins_id='72' and user_id='11688' and host_email_type=4);


but also want to update if
host_email_email,event_code_id,event_code_admins_id,user_id,host_email_type
is already there


I think it would be too difficult to have 6 keys in one table,
so I think command would be easier

You can use one key which references multiple columns.  You might consider REPLACE INTO (which is a unique-to-MySQL extension of the standard).  You might consider ON DUPLICATE KEY UPDATE.

changed to replace into
'new value'

replace into host_email (event_code_id,event_code_admins_id,user_id,host_email_name,host_email_first_name,host_email_last_name,host_email_email,host_email_type,host_email_member,nominate,course1,course2,course3,course4,additional_notes) select '87','72','11688','new value','robert','jones','email@email.com',4, '1', '', '1', '6', '3', '', 'almost vegitarian' from dual where not exists (select 1 from host_email where host_email_email = 'email@email.com' and event_code_id='87' and event_code_admins_id='72' and user_id='11688' and host_email_type=4);

I think we would need the SSCCE, including some data to test with.
