Обсуждение: insert question..

I'm looking for an example on how to insert static data and information from a select at the same time..

currently I'm doing:

insert into performance (start,finish) select min(poll_time),max(poll_time) from poll

I need to add a 3rd field that is static so I would have something like this


insert into performance (name,start,finish) travis,select min(poll_time),max(poll_time) from poll

Thanks,

Travis

If travis is really a constant then you could do:
insert into performance (name,start,finish)
  select 'travis', min(poll_time), max(poll_time) from poll;

Another option that might be faster (if there is an index on poll_time)
because you are using max and min is:
insert into performance (name,start,finish)
  values ('travis',
    (select poll_time from poll order by poll_time limit 1),
    (select poll_time from poll order by poll_time desc limit 1))

insert into performance (name,start,finish)
select 'Travis', min(poll_time),max(poll_time) from poll

Almost :-)

The correct syntax is:

insert into performance (name,start,finish) select 'travis', min(poll_time),max(poll_time) from poll;

I hope, it helps.
