Question

So, i’ve come up with this query wich works perfectly fine when executed. However, since I want to use the pagination from Zend, the query has to be through an adapter.

This is the query that has to be converted: (i’ve cut the query so only the important part is here. I am aware of the fact that you can’t run this query LOL)

//snip
WHERE
    city IN (
        SELECT 
            Plaatsnaam
        FROM
            plaatsnamen
        WHERE
            Latitude 
                BETWEEN 
                    ?
                AND 
                    ?
        AND
            Longitude
                BETWEEN
                    ?
                AND
                    ?       
    )
//snip

Works perfectly fine! However.. As you can see, i’m using an “advanced” WHERE IN case. Somehow, i can’t get this converted and i’m stuck.

This is what it has to be converted to:

$db = Zend_Db_Table::getDefaultAdapter();                
$select = $db->select('gethousecity.id, city')
                                ->from('gethousecity')
                                    ->join('houses_props', 'houses_props.id = gethousecity.id')
                                ->where('city IN ()') // HOW TO CONVERT THE UPPER QUERY TO FIT IT HERE?
                                ->where('is_online = 1')
                                ->where('houses_props.prop_name = ?', 'something')
                                ->where('houses_props.prop_value BETWEEN ? AND ?', array(1,2));

I haven’t found any documentation at all on how to convert the query into some format that fits here. Does anyone have any idea? Mostly because I need to insert some values and ZF is rewriting some weird shit there.

I’m kinda stuck now, any help would be awesome!

Answer 1

Subqueries work just fine.

$select1->cols('id')->where('date > NOW()');
$select2->where('id IN (?)', $select1);

If the problem is the complex where, than you can use named parameters.

$select1 = $db->select();
$select2 = $db->select();
$select1->from('plaatsnamen', array('Plaatsnaam'))
        ->where('Latitude BETWEEN :latmin AND :latmax')
        ->where('Longitude BETWEEN :longmin AND :longmax');
$select2->from('gethousecity')
        ->join('houses_props', 'houses_props.id = gethousecity.id')
        ->where('city IN ?', $select1) // HOW TO CONVERT THE UPPER QUERY TO FIT IT HERE?
        ->where('is_online = 1')
        ->where('houses_props.prop_name = ?', 'something')
        ->where('houses_props.prop_value BETWEEN :propsmin AND :propsmax');
die($select2);

Returns:

SELECT `gethousecity`.*, `houses_props`.*
FROM `gethousecity`
INNER JOIN `houses_props` ON houses_props.id = gethousecity.id
WHERE 
    (city IN (
        SELECT `plaatsnamen`.`Plaatsnaam`
        FROM `plaatsnamen`
        WHERE 
        (Latitude BETWEEN :latmin AND :latmax) AND
        (Longitude BETWEEN :longmin AND :longmax)
    )) AND
    (is_online = 1) AND
    (houses_props.prop_name = 'something') AND
    (houses_props.prop_value BETWEEN :propsmin AND :propsmax)

Which should work with named parameters, as seen in manual

$bind = array(
    ':latmin' => 10,
    ':latmax' => 3,
    '...' => '...',
);
$db->fetchAll($select2, $bind);
