Question

I am looking to export a large amount of data into a CSV file for user download using Zend Framework. Is there any way to use Zend_Db\'s functionaity and use the \"INTO OUTFILE\

You can try to build a base query, convert it to a string and then append from there. The advantage being that you can use Zend's bind functionality (at least for the where clause), in case you need that. Like so:

$filename = 'tmp/test.csv';
$value = 'given';

 // build base query making use of Zend´s binding feature.
$select = $this->_db->select()
    ->from(test_table, array(a,b,a+b))
    ->where('column = ?', $value)
    ->__toString()

 // append the rest of the query.
.' INTO OUTFILE "'. $filename .'"'
.' FIELDS TERMINATED BY ";"'
.' OPTIONALLY ENCLOSED BY "\\""'
.' LINES TERMINATED BY "\\n"';

 // execute query.
$this->_db->query($select);
