thanks jared,
If you can match a person by their email, why not just SELECT by email
only
(and return the persons information)?
'cause some members can be added to database by administrator and maybe
they don't have email address at all. or several memebers can use the
same email address (sale@xxxxxxxxxxxxxxx) and then macthing last name is
kind of "required". that's how it works now and can't change it.
Consider, as well, that each time you're calling a database, you're
slowing
down the response of the page. So, while making a bunch of small calls
might
not seem like that much, consider:
||||||| x |||||||
||||||| a |||||||
||||||| b |||||||
Versus
||||||| x, a, b |||||||
The letters represent the request/response data (what you're giving to
get,
then get back), and the pipes (|) are the overhead to process, send,
receive
(on DB), process (on DB), send (on DB), receive, process, return to code.
The overhead and latency used to complete one request makes it a quicker,
less "heavy" operation. If you did the first a couple hundred or thousand
times, I would bet your page would drag to a halt while it loads...
agree. now, I have to figure it out HOW? :-)
I was looking at levenshtein, though, I think the richard's solution is
just enough:
select member_id, first_name, last_name, email, ...,
(5*(first_name='$first_name) + 2*(first_name='$first_name')) as score
from members
where score > 0
though, I'm getting error: "Unknown column 'score' in where clause"?!?
thanks jared.
