How to implement sql query in zend db - php

Question

I tried myself for another queries but this one is more complex for me as i am new to zend. Please help me i tried different ways but not worked.
Tour Id fetching from another query
$tourId = $row2 ['test_public_id'];
$query = select count(ms.test_public_id) as total_views, ms1.recent_views from test_stats
ms join (select count(test_stats.test_public_id) as recent_views
from test_stats where test_stats.test_public_id = '$tourId'
and test_stats.updated_on > DATE_SUB(CURDATE(), INTERVAL 7 DAY)) ms1
where ms.test_public_id ='$tourId'" ;

Answer 1

Something like that should work:
$subselect = $dbAdapther->select()->from(
array('test_stats' => 'test_stats'),
array(
'(COUNT(test_public_id)) AS recent_views'
)
)->where(
$dbAdapther->quoteInto('test_stats.test_public_id = ?', $tourId)
)->where(
'test_stats.updated_on > DATE_SUB(CURDATE(), INTERVAL 7 DAY)'
);
$select = $dbAdapther->select()->from(
array('ms' => 'test_stats'),
array(
'(COUNT(ms.test_public_id)) AS total_views' // COUNT should be in brackets to preevent Zend from interpreting it as a field name
)
)->join(
array('ms1' => $subselect),
'',
array(
'ms1.recent_views'
)
)->where(
$dbAdapther->quoteInto('ms.test_public_id = ?', $tourId)'
);
Although I'd have your query broken into two separate ones or, more precisely, write a universal "get number of views" query with a date as its parameter, and then I'd be calling it twice, with or without the date.
But if you still need to get those two figures in one go in a single row (i.e. you can't use UNION instead of your unnecessary JOIN), I'd recommend you to use the following code instead:
$select = $dbAdapther->select()->from(
array('ms' => 'test_stats'),
array(
'(COUNT(ms.test_public_id)) AS total_views',
'(
COUNT(
CASE
WHEN ms.updated_on > DATE_SUB(CURDATE(), INTERVAL 7 DAY)) THEN ms.test_public_id
ELSE NULL
END
)
) AS recent_views'
)
)->where(
$dbAdapther->quoteInto('ms.test_public_id = ?', $tourId)
);

Answer 2

I'm new too in Zend, but I've tried this sample and it's works.
See this tutorial, I hope it'll help you:
http://framework.zend.com/manual/en/zend.db.select.html
or you can do this:
$db = Zend_Db_Table_Abstract::getDefaultAdapter();
$stmt = $db->query($query);
$result = $stmt->fetchAll();
