Hi,

Anyone can help for fast update? The update statement below take 4hours for 65k records.

update exclusive a
set a.deleted_date=now()
where concat(a.lname,a.fname,a.mname,a.address,a.city,a.state,a.zip) not in
(select concat(b.lname,b.fname,b.mname,b.address,b.city,b.state,b.zip) from
exclusive_temp b)
and a.deleted_date is null;

Thanks in advanced.

Regards,
