Question

I have a multi-table SQL query.

My need is: The query should I generate a single line by ‘etablissement_id’ … and all information that I want to be back in the same query.

The problem is that this query is currently on a table where “establishment” may have “multiple photos” and suddenly, my query I currently generates several lines for the same id…

I want the following statement – LEFT JOINetablissementContenuMultimediaON etablissement.etablissement_id = etablissementContenuMultimedia.etablissementContenuMultimedia_etablissementId – only a single multimedia content is displayed. Is it possible to do this in the query below?

Here is the generated query.

SELECT DISTINCT `etablissement`. * , `etablissementContenuMultimedia`. * , `misEnAvant`. * , `quartier`. *
FROM `etablissement`
LEFT JOIN `etablissementContenuMultimedia` ON etablissement.etablissement_id = etablissementContenuMultimedia.etablissementContenuMultimedia_etablissementId
LEFT JOIN `misEnAvant` ON misEnAvant.misEnAvant_etablissementId = etablissement.etablissement_id
LEFT JOIN `quartier` ON quartier_id = etablissement_quartierId
WHERE (
    misEnAvant_typeMisEnAvantId =1
    AND (
        misEnAvant_dateDebut <= CURRENT_DATE
        AND CURRENT_DATE <= misEnAvant_dateFin
    )
)
AND (
    etablissement_isActive =1
)
ORDER BY `etablissement`.`etablissement_id` ASC
LIMIT 0 , 30

Here is the code used ZF

public function find (){
    $db = Zend_Db_Table::getDefaultAdapter();
    $oSelect = $db->select();
    $oSelect->distinct()
            ->from('etablissement')
            ->joinLeft('etablissementContenuMultimedia', 'etablissement.etablissement_id = etablissementContenuMultimedia.etablissementContenuMultimedia_etablissementId')
            ->joinLeft('misEnAvant', 'misEnAvant.misEnAvant_etablissementId = etablissement.etablissement_id')
            ->joinLeft('quartier', 'quartier_id = etablissement_quartierId ')
            ->where ('misEnAvant_typeMisEnAvantId = 1 AND (misEnAvant_dateDebut <= CURRENT_DATE AND CURRENT_DATE <= misEnAvant_dateFin) ')
            ->where ('etablissement_isActive = 1')
            ->order(new Zend_Db_Expr('RAND()'));


    $zSql = $oSelect->__toString();

    if(isset($_GET['debug']) AND $_GET['debug'] == 1)
        echo $zSql ;
    //die();

    $oResultEtablissement = $db->fetchAll($oSelect);   

    return $oResultEtablissement ;
}

Can you help me?

I took the time to redo the whole model of the database … and now it works. There was no solution for a system as flawed
