Confused... Zend_db

Recommended Posts

Hi there,


I have run through the "Getting started with zend..." tutorial which went fairly smoothly.  I'm now trying to run a simple query but Zend keeps throwing the error:


Fatal error: Uncaught exception 'Zend_Db_Statement_Exception' with message 'SQLSTATE[21000]: Cardinality violation: 1241 Operand should contain 1 column(s)' in /Library/WebServer/Documents/library/Zend/Db/Statement/Pdo.php:238 Stack trace: #0 /Library/WebServer/Documents/library/Zend/Db/Statement.php(283): Zend_Db_Statement_Pdo->_execute(Array) #1 /Library/WebServer/Documents/library/Zend/Db/Adapter/Abstract.php(430): Zend_Db_Statement->execute(Array) #2 /Library/WebServer/Documents/library/Zend/Db/Adapter/Pdo/Abstract.php(220): Zend_Db_Adapter_Abstract->query(Object(Zend_Db_Table_Select), Array) #3 /Library/WebServer/Documents/library/Zend/Db/Table/Abstract.php(1189): Zend_Db_Adapter_Pdo_Abstract->query(Object(Zend_Db_Table_Select)) #4 /Library/WebServer/Documents/library/Zend/Db/Table/Abstract.php(1044): Zend_Db_Table_Abstract->_fetch(Object(Zend_Db_Table_Select)) #5 /Library/WebServer/Documents/villa4life/application/controllers/BodymoorheathController.php(10): Zend_Db_Table_Abstract->fetchAll('SELECT * FROM c...') #6 in /Library/WebServer/Documents/library/Zend/Db/Statement/Pdo.php on line 238


I believe this is the problem code:


$this->view->comments = $comments->fetchAll('SELECT * FROM comments ORDER BY dateTime');


Any suggestions.  I'm very confused by the fundamentals of executing queries in Zend.

I'm not sure what's the error about, so let's try a different approach :)


Why don't you use the model for working with the database? That's the point of the MVC.


I'll try to write a basic model for your comments table, based on the info provided. This model should go in: /Library/WebServer/Documents/villa4life/application/models/Comments.php



class Comments extends Zend_Db_Table
protected $_name = 'comments'; // The table name
protected $_primary = 'id_comment'; // The name of the primary column
protected $_schema = 'database_name'; // Name of the database

public function getAll()
	$sql = $this->select()->from('comments');	
	$rowsetComments = $this->fetchAll($sql);
	return $rowsetComments;




Now, the 'id_comment', 'comment', 'author' and the 'date' columns here are fictitious, change them to suit your scenario. To use it in the controller, use it like this:

// some where in some action function...
$comments = new Comments();
$this->view->comment = $comments->getAll();

And that should do it...
