Q: How can i make mysql query search in multiple rows

What i want to make script search is:

if kat_preces_params.params_id is equal to 124 AND kat_preces_params.nosaukums is  LIKE '%$make%',

AND if kat_preces_params.params_id is equal to 125 AND kat_preces_params.nosaukums is LIKE '%$model%' 

AND IF kat_preces_params.params_id is equal to 126 AND kat_preces_params.nosaukums <=2009 AND kat_preces_params.nosaukums >=2000

How i tried to do it (i know it’s wrong, ’cause it doesn’t display right values…):

PHP checking the year:

if($year == '2010 - ...'){
    $gads = 'kat_preces_params.nosaukums <=2010';
}
elseif($year == '2000 - 2009'){
    $gads = 'kat_preces_params.nosaukums <=2009 AND kat_preces_params.nosaukums >=2000';
}
elseif($year == '2000 - 2004'){
    $gads = "kat_preces_params.nosaukums <=2004 AND kat_preces_params.nosaukums >= 2000";
}
elseif($year == '... - 1999'){
    $gads = "kat_preces_params.nosaukums <=1991";

}

AND I have a mysql query looking like this:

SELECT kat_prece.*, kat_preces_params.* FROM kat_prece, kat_preces_params WHERE pamat_kat_sad = '$cat_mod_id' 
AND kat_prece.preces_id = kat_preces_params.preces_id 
AND ((
    kat_preces_params.params_id=124 
    AND kat_preces_params.nosaukums LIKE '%$make%'
    ) 
    || (
        kat_preces_params.params_id=125 
        AND kat_preces_params.nosaukums LIKE '%$model%'
        ) 
    AND kat_preces_params.params_id=126 
    AND $gads
    )

$model and $make are requested values

Maybe it’s possible with INNER JOIN or somehow (don’t know nothing about inner join)?

THANK YOU!

• Change the $gads definition to this: kat_preces_params.nosaukums BETWEEN 2000 AND 2009 and so on.
• From your first set of prerequisites, I think what you need is something like: kat_preces_params.params_id IN (124, 125, 126) AND kat_preces_params.nosaukums LIKE '%$make%' OR kat_preces_params.nosaukums LIKE '%$model%'.

What I don’t understand is that what type of data is there in kat_preces_params.nosaukums where you are once comparing them as INTEGER and another time, as STRINGS.
