Question

Okay i have mysql query, and i’d like to search both parameters in table_1
i’ll try showing the idea with “php”

if(table_2_params.params_id == 124){
   //select LIKE  "%EXTEC (Sandvik)%" from  table_2_params.nosaukums
}
elseif(table_2_params.params_id == 126){
  //SELECT  FROM table_2_params WHERE nosaukums is BETWEEN  "2010" AND  "2012"
}

I want to query display first AND second parameter…(both of them to match)
daymn i hope you will understand what i want to say…

Okay here’s the
mysql query:

 SELECT table_1 . * , table_2_params . * 
    FROM table_1, table_2_params
    WHERE table_1.pamat_kat_sad =  '756'
    AND table_1.preces_id = table_2_params.preces_id
    AND (
        (
        table_2_params.params_id =124
        AND table_2_params.nosaukums LIKE  "%EXTEC (Sandvik)%"
        )
        AND (
        table_2_params.params_id =126
        AND table_2_params.nosaukums
        BETWEEN  "2010"
        AND  "2012"
        )
    )
    ORDER BY table_1.preces_id DESC

Problem might be that the table_2_params.nosaukums type is longtext …

If i select only with

    AND (
    table_2_params.params_id =126
    AND table_2_params.nosaukums
    BETWEEN  "2010"
    AND  "2012"
    )

it displays correct year…
AND if i select only with

(
    table_2_params.params_id =124
    AND table_2_params.nosaukums LIKE  "%EXTEC (Sandvik)%"
    )

it also displays correct values…

But i cant make them both work together..

Please help me!

Thank you!

If you want two sets of conditions just use OR. You should also note that joins between tables should be performed using (INNER|LEFT) JOIN :

SELECT
    table_1.*
    , table_2_params.* 
FROM
    table_1
    INNER JOIN table_2_params
        ON table_1.preces_id = table_2_params.preces_id
WHERE
    table_1.pamat_kat_sad =  '756'
    AND
    (
        (
            table_2_params.params_id =124
            AND table_2_params.nosaukums LIKE '%EXTEC (Sandvik)%'
        )
        OR
        (
            table_2_params.params_id =126
            AND table_2_params.nosaukums BETWEEN '2010' AND '2012'
        )
    )
ORDER BY
    table_1.preces_id DESC

And finally your query may perform poorly, since mysql won’t be able to use any index with AND table_2_params.nosaukums LIKE '%EXTEC (Sandvik)%'
