selecting the 'best' match
I have a hold car data such as color, model, make, year, etc. I want to allow the user to answer some questions and I'll present them with the car that 'best' matches their criteria. How do I do this? I still want to return ones that don't match exactly but want the closer matches ordered at the top: Table:cars columns: car_id, make, model, year, color, condition So if the user enterrs: model: Toyota year: 1998 condition:great color: blue I would show them a blue 1998 good conditioned camry first but farther down in the list might still have a blue good condition 98 Honda. Thanks!
Re: selecting the 'best' match
Thanks but doing it in code would require me to pull in the entire car table and process it. With potentially tons of rows, seems like I should be able to use the db to get those.

I would do it in code, though - it may or may not be less efficient, but it'll be easier to maintain and read.

load data infile
Hello all, I have a file where the data looks like this: 1,23,345,45; 34,4,444,1er; I am then trying to load that data using the load data local infile and this statement: Load data local infile '/httpd/htdocs/sql/loader.sql' into table vehicles fields terminated by ',' enclosed by ' lines terminated by ';' The rows in loader.sql contain all of the columns so I am not specifiying the columns and when I run this it tells me it loads 258 rows yet when I look in the db, these rows aren't there. What am I doing wrong? Thanks! -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
