Or, if using bound paramaters (and you should be):
insert into t (a, b, c, d, e, idate)
select ?, b, c, ?, e, ?
from t
where a = ?1
order by idate desc
limit 1;
then you bind the three parameters a, d, idate.
Whether you want "order by idate desc" or "order by idate" depends on whether
you want the newest or oldest record to be the template.
