I was trying to figure how to use Update from Zend\Db\Sql using a Join in Zend Framework 2.
In the documentation they say that the only allowed method for Update are just where() and set(), so I would like to know if there are some alternative ways to get the same results.
You could do something like this (untested):
$db = new DbAdapter(
array(
'driver' => 'Pdo',
'dsn' => 'mysql:dbname=mydb;host=localhost',
'username' => 'root',
'password' => '',
)
);
$sql = 'UPDATE t1 JOIN t2 ON t1.id = t2.id SET t1.atr = 1';
$sql_result = $db->createStatement($sql )->execute();
if($sql_result->count() > 0){
echo "DONE";
}
I don't believe this is possible with the 'update()' method provided by the Zend Db Adapter.
You can, however, run the query manually using the adapter. Something like:
// $adapter is an instance of Zend_Db_Adapter
$adapter->query(YOUR QUERY HERE);
This seems to be a duplicate of Update with join using Zend-framework
Seems to be no way to do with this with Zend.

My query gets the timeout error on each run. Its a pagination with joins.
I want to debug the SQL, but since I get a timeout, I can't see it.
How can I see the compiled SQL Query before execution?
Some cake code:
$this -> paginate = array(
'limit' => '16',
'joins' => array( array(
'table' => 'products',
'alias' => 'Product',
'type' => 'LEFT',
'conditions' => array('ProductModel.id = Product.product_model_id')
)),
'fields' => array(
'COUNT(Product.product_model_id) as Counter',
'ProductModel.name'
),
'conditions' => array(
'ProductModel.category_id' => $category_id,
),
'group' => array('ProductModel.id')
);
First off, set the debug variable to 2 in app/config/config.php.
Then add:
<?php echo $this->element('sql_dump');?>
at the end of your layout. This should actually be commented out in your default cake layout.
You will now be able see all SQL queries that go to the database.
Now copy the query and use the SQL EXPLAIN command (link is for MySQL) over the database to see what the query does in the DBMS. For more on CakePHP debugging check here.
Since your script doesn't even render you can try to get the latest log directly from the datasource with:
function getLastQuery()
{
$dbo = $this->getDatasource();
$logs = $dbo->getLog();
$lastLog = end($logs['log']);
return $lastLog['query'];
}
This needs to be in a model since the getDatasource() function is defined in a model.
Inspect the whole $logs variable and see what's in there.
One more thing you can do is ....
Go to Cake/Model/DataSource/DboSource.php and locate function execute() and print $sql variable.
That should print the sql.
This certainly is not be the cleanest way (as you are changing Cake directory) .. but certainly would be quickest just to debug if something is not working with sql.
Try...
function getLastQuery($model) {
$dbo = $model->getDatasource();
$logData = $dbo->getLog();
$getLog = end($logData['log']);
echo $getLog['query'];
}
Simple way to show all executed query of your given model:
$sqllog = $this->ModelName->getDataSource()->getLog(false, false);
debug($sqllog);
class YourController extends AppController {
function testfunc(){
$this->Model->find('all', $options);
echo 'SQL: '.$this->getLastQuery();
}
function getLastQuery()
{
$dbo = ConnectionManager::getDataSource('default');
$logs = $dbo->getLog();
$lastLog = end($logs['log']);
return $lastLog['query'];
}
}
or you can get all the query by adding following line in to the function execute() in lib/Cake/Model/DataSource.php
Debugger::dump($sql);
set the debug variable to 2 in app/config/config.php.
echo $this->Payment->save();
Out put like =>SQL Query: INSERT INTO photoora_photoorange.payments VALUES (*******)
[insert query][2]
set the debug variable to 2 in app/config/config.php.

I have followed the zend instructions for implement my web Authentication using a database table.
It's exactly the same code, but when render the page, the following exceptions appears:
Zend\Authentication\Adapter\Exception\RuntimeException
File:
C:\xampp\htdocs\pfc\vendor\ZF2\library\Zend\Authentication\Adapter\DbTable.php
Mensaje:
The supplied parameters to DbTable failed to produce a valid sql statement, please
check table and column names for validity.
produced by this other:
Zend\Db\Adapter\Exception\InvalidQueryException
File:
C:\xampp\htdocs\pfc\vendor\ZF2\library\Zend\Db\Adapter\Driver\Mysqli\Statement.php
Mensaje:
Statement couldn't be produced with sql: SELECT `users`.*, (CASE WHEN `password` = ?
THEN 1 ELSE 0 END) AS `zend_auth_credential_match` FROM `users` WHERE `mail` = ?
Seems to be that Statement.php can not execute the sql of above, but I send the sql by phpmyadmin replacing the ? for strings and work ok.
I am sure that $dbAdapter works ok also because I have tested it and the columns name are
"mail" and "password".
This in my code, also I put the $dbAdapter test code.
$dbAdapter = new DbAdapter(array( //This DbAdapter Work ok sure!!
'driver' => 'Mysqli',
'database' => 'securedraw',
'username' => 'root',
'password' => ''
));
$fp = function($name) use ($dbAdapter) { return $dbAdapter->driver->formatParameterName($name);};
$sql = 'SELECT * FROM ' . $qi('users') . ' WHERE id = ' . $fp('id');
$statement = $dbAdapter->query($sql);
$parameters = array('id' => 1);
$sqlResult = $statement->execute($parameters);
$row = $sqlResult->current();
$mail = $row['mail'];
$password = $row['password']; //until here test $dbAdapter exitly!!
//Start the auth proccess!!
$authAdapter = new AuthDbTableAdapter($dbAdapter);
$authAdapter->setTableName('users')
->setIdentityColumn('mail')
->setCredentialColumn('password');
$authAdapter->setIdentity('josep')
->setCredential('josep');
$authResult = $authAdapter->authenticate(); //This is the fail method!!!
After more research on the subject, I discovered that if changed the driver of the dbAdapter to pdo_mysql, authenticate method works ok.
The problem is I don't want use PDO because the SGBD won't change in the future.
Somebody know because happen this?
This may seems old but I was able to solve this error. This error is caused from you MySQL version.
This one works for me. All you need to do is to remove the driver_options from your db setup, this code is usually located at your global.php or .local.php from your Config file.
Change FROM:
'db' => array(
'driver' => 'Pdo_Mysql',
'dsn' => 'mysql:dbname=dbName;host=localhost',
'username' => 'dbUser',
'password' => 'dbPass',
'driver_options' => array(
PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES \'UTF8\''
),
),
TO
'db' => array(
'driver' => 'Pdo_Mysql',
'dsn' => 'mysql:dbname=dbName;host=localhost',
'username' => 'dbUser',
'password' => 'dbPass',
),
Thank you. This solution solved my problem.
I have the following example code:
$dataProvider = new CActiveDataProvider('firstTable',
array('criteria' => array(
'select' => 't.firstfield,secondTable.secondfield',
'join' => 'join secondTable on secondTable.id=t.secondTable_id',
),
'pagination' => array(
'pageSize' => 10,
),
));
$results=$dataProvider->getData();
After running the code above, firstField (from the model table - firstTable) is available in the object, but secondField (from the joined table - secondTable) is not.
Can anyone provide assistance on what is wrong with the code or why the "select" option is not picking up the secondField?
it would be better if you use CDbCriteria, that has a better solution to join table with the help of relations. I can show the example with CDbCriteria.
$criteria = new CDbCriteria;
$criteria->select = 'firstfield';
$criteria->with = array('secondTable_relation'=>array('select'=>'secondfield'));
$dataProvider = new CActiveDataProvider('firstTable',
array('criteria' => $criteria,
'pagination' => array(
'pageSize' => 10,
),
));
$results=$dataProvider->getData();
secondTable_relation is a relation name with secondTable.
Can anyone provide assistance on what is wrong with the code or why the "select" option is not picking up the secondField?
Answer:
That is happening because you have not selected the field which relates the two tables, i.e the foreign key in firstTable : secondTable_id. So if you do:
'select' => 't.firstfield,t.secondTable_id,secondTable.secondfield',
you will be able to access the secondField of secondTable:
$singleresultrow->secondTableRelationName['secondField'];// a single result row can be obtained by foreach iteration over $results
However there will still be another query (Lazy Loading) when you access the secondField. And the initial(before lazy) object returned will not have the secondTable object filled.
The problem i think lies in the fact that by default yii accesses the related fields by lazy loading, and for that to happen the related foreign_key should be present in the model you are trying to make a dataprovider of, here it is firstTable, and the foreign_key secondTable_id.
I have a code
$command = Yii::app()->db->createCommand()
->update(
'queue q',
array('i.status_id' => $status_id)
)
->join('item i', 'q.item_id = i.item_id')
->where('IN', 'queue_id', $ids);
after I call $command->buildQuery() I get an error:
CDbCommand failed to execute the SQL statement: Invalid parameter number: parameter was not defined. The SQL statement executed was: UPDATE queue q SET i.status_id=:i.status_id
The impression is that it does not see the join and where commands.
What the problem?
Your code is valid with the newest Yii version. This MySQL-specific functionality has been added as of 1.1.14: https://github.com/yiisoft/yii/commit/ed49b77ca059c0895be17df5813ee1e83d4c916d.
The where clause should be in the update() function like this
Yii::app()->db->createCommand()
->update(
'queue q',
array('i.status_id' => $status_id),array('in', 'queue_id', $ids)
);
And regarding the JOIN part there is a open bug at https://github.com/yiisoft/yii/issues/124 (Im not sure. Correct me if Im wrong). Please let me know if there is a workaround.
You have to bind the parameters:
$command = Yii::app()->db->createCommand()
->update(
'queue q',
array('i.status_id' => ':status_id'),
array('in', 'queue_id', $ids),
array(':status_id' => $status_id),
)
->join('item i', 'q.item_id = i.item_id');
Having come across this problem a few times in my projects I have come-up with the following Yii work-around using CDbCriteria which is a little hacky, but gives the security of param count matching.
When applied to your example my code would be (guessing a little bit of your structure):
$ids = array(1,2,3,4,5);
$criteria = new CDbCriteria();
$criteria->addInCondition('i.queue_id',$ids);
$sql = '
UPDATE queue q
JOIN item i
ON q.item_id = i.item_id
SET i.status_id = :status
WHERE '.$criteria->condition;
$command = Yii::app()->db->createCommand($sql);
$command->bindValue('status',$status);
$command->bindValues($criteria->params);
$rows = $command->execute();
The ORM in FuelPHP has an update example that looks like this:
$entry = Model_Article::find(4);
$entry->title = 'My first edit';
$entry->author = 'Total n00b';
$entry->save();
I'm wondering if there is an ability for me to update w/ something like this:
$values = array(
'this' => $that
);
Model_Article::find(4)->save($values);
The insert ability allows for passing arrays of values:
$props = array('property' => 'something');
$new = Model_Example::forge($props)->save();
But I see no example of doing the same thing w/ the update ability.
EDIT: It appears Model_Example::find(4)->values($array)->save(); is what I'm looking for.
