-- create statement, assign to user variable
set @s = concat('
select last_logon.host_name_short
from last_logon
left join mcafee on last_logon.host_name_short = last_logon.host_name_short
where mcafee.host_name_short is null
and last_logon.host_name_short like \'w%\'
into outfile \'Missing-',date_format(now(),'%Y%m%d%H%i'),'.txt\'');
-- display so you can verify what it looks like
select @s;
-- prepare statement, execute it, discard it
prepare s from @s;
execute s;
deallocate prepare s;
Note: I added a '.' before 'txt' and a closing quote to the file name.
