I'm trying to do a join on 2 tables in Zend, using the DbTable / model / mapper structure. If, in my mapper, I do this:
$select = $this->getDbTable()->select(Zend_Db_Table::SELECT_WITH_FROM_PART)
->setIntegrityCheck(false)
->join('images', 'images.oldFilename =
availablePictures.filename')
->where('images.ref IS NOT NULL');
$resultSet = $this->getDbTable()->fetchAll( $select );
it works like a charm, but if I try the same thing with IS NULL instead of NOT NULL, I get nothing where I should get a result set of several rows, just like when I try it directly in MySQL with
SELECT *
FROM (
`availablePictures` AS a
LEFT JOIN `images` AS i ON a.filename = i.oldFilename
)
WHERE i.`ref` IS NULL
I get the impression Zend doesn't like my IS NULL or am I doing something wrong?
The solution was to be found in Machine's comment on my original post. Doing what he suggested I noticed that Zend created an inner join as I was using the wrong select method, so:
$select = $this->getDbTable()->select(Zend_Db_Table::SELECT_WITH_FROM_PART)
->setIntegrityCheck(false)
->joinLeft('images', 'images.oldFilename =
availablePictures.filename')
->where('images.ref IS NOT NULL');
$resultSet = $this->getDbTable()->fetchAll( $select );
is how it should be.
