How can I view the SQL Query on model->save() in CakePHP 3? Is there any way to do this? I want to get the specific sql query e.g when I save new entity.
I need it because I want to save that to a log file in some cases.
My bootstrap.php log config:
Log::config('current', [
'className' => 'File',
'path' => LOGS.DS.date('Y-m').DS,
'scopes' => ['daily','queriesLog'],
'file' => date('Y-m-d'),
]);
What i want to get:
e.g when i save entity:
$this->Clients->save($client);
i want to log something and i want to save INSERT sql query with this log
Log::warning('test\n', ['scope' => ['daily']]);
A solution could be using query logging
http://book.cakephp.org/3.0/en/orm/database-basics.html#query-logging
you can turn query logging on just when you save your model and then turn it off
For example I have a Comments model
In my bootstrap.php I did
Log::config('current',
[
'className' => 'File',
'path' => LOGS.date('Y-m').DS, // you don't need a DS between LOGS and date()
'scopes' => ['daily','queriesLog'],
'file' => date('Y-m-d'),
]);
and in my controller I did
$conn = \Cake\Datasource\ConnectionManager::get('default');
$comment = $this->Comments->get(5620); // 5620 is the id of one comments of mine
$conn->logQueries(true);
$comment = $this->Comments->get(5619); // 5619 is onother id of one comments of mine
$comment->text = 'Test';
$this->Comments->save($comment);
$conn->logQueries(false);
In this way a file is created in the logs folder and the file contains the following
2015-12-16 13:38:35 Debug: SELECT ... WHERE Comments.id = 5619 LIMIT 1
2015-12-16 13:38:35 Debug: BEGIN
2015-12-16 13:38:35 Debug: UPDATE comments SET text = 'Test' WHERE id = 5619
2015-12-16 13:38:35 Debug: COMMIT
note that the query used to get comment #5620 has not been logged
Also note that this works if you don't have debugkit enabled
Put this into model
function getLastQuery() {
Configure::write(‘debug’,false);
$dbo = $this->getDatasource();
$logs = $dbo->getLog();
$lastLog = end($logs['log']);
$latQuery = $lastLog['query'];
echo "<pre>";
print_r($latQuery);
}
after $this->save($data);
call that function
$this->getLastQuery();
and echo it.
Try it.

while I am updating record it display above error.

I added 2 primary keys for table.
table structure:
After adding primary keys to table need to flush the cache
To refresh the database cache :
Load all tables of the application in the schema
Yii::app()->db->schema->getTables();
clear the cache of all loaded tables
Yii::app()->db->schema->refresh();
If you want to refresh only one table, you can also do :
Yii::app()->db->schema->getTable('tablename', true);
After that It works fine.
I am using the Firebase PHP Admin SDK: https://firebase-php.readthedocs.io/en/stable/realtime-database.html#update-specific-fields
Here is the example it gives to update specific fields:
$uid = 'some-user-id';
$postData = [
'title' => 'My awesome post title',
'body' => 'This text should be longer',
];
// Create a key for a new post
$newPostKey = $db->getReference('posts')->push()->getKey();
$updates = [
'posts/'.$newPostKey => $postData,
'user-posts/'.$uid.'/'.$newPostKey => $postData,
];
$db->getReference() // this is the root reference
->update($updates);
From that, I created a users class and in that I have an update function. Like so:
public function update() {
$data = array('users' => array('1' => 'David'));
$this->database->getReference()->update($data);
return true;
}
In my database I have this structure:
Now if I run that function $users->update();
It removes the other child and only leaves David. Like so:
How can I update only a specific value of a specified key without it overriding the other data?
There's nothing specific to PHP here. That's the way Realtime Database update operations work. If you want a minimal update, you have to target the deepest key that you want to update. In your case, since you're storing an array type object, the keys are the number indexes of the array items you've written. If you want to modify one of them, you need to build a reference that includes the child number you want update. In that case, none of the sibling values will be touched.
Try this instead:
$this->database->getReference('users')->update(array('1' => 'David'));
Notice here that the update is rooted at "users", and you're updating just the immediate child "1" of that.
The example on docs is a little bit hard to grasp as a beginner. I have made it simpler for you to understand.
Once you get the newPostKey, prepare the url for child and run the code. It will only change the specific fields.
$ref = 'users/' . $newPostKey;
$updates = [
'title' => 'Updated title',
'body' => 'Updated body text',
];
$set = $db->getReference($ref)->update($updates);
I have an event table with this fields:
I use this code to insert data in this table :
$oneEvent = array(
'trainer_id' => $event['trainer_id'],
'formation_id' => $event['formation_id'],
'title' => $event['title'],
'start' => $event['start'][$i],
'end' => $event['end'][$i],
);
$success = $this->Event->save($oneEvent);
$events_id= $this->Event->inserted_ids;
when I run this code I get true and ID of insert element (showed using debug)
but in database i can't see this field never !!!!.
and when I insert data in phpmyadmin when this request INSERT INTO events(title,start, end, trainer_id, formation_id) VALUES ('Départ B','2016-11-18 10:00:00','2016-11-18 11:00:00','13','1') it worked
I didn't know what happen here !!??
I solved the problem by using $dataSource->commit(); after calling save() function
I'm doing this:
$students = Student::find()->all();
return $this->render('process', array('students' => $students));
and then this in the view:
foreach($students as $student)
{
echo $student->name . ', ';
echo $student->getQuizActivitiesCount(); ?> <br /> <?php
}
i would like to see the sql query being performed. a student "has many" quiz activities, and the query performs perfectly, but i need to see the raw SQL. is this possible?
Method 1
With relations that return yii\db\ActiveQuery instance it's possible to extract the raw SQL query directly in code for example with var_dump().
For example if we have user relation:
/**
* #return \yii\db\ActiveQuery
*/
public function getUser()
{
return $this->hasOne(User::className(), ['id' => 'user_id']);
}
You can then var_dump() the raw SQL like that:
var_dump($model->getUser()->prepare(Yii::$app->db->queryBuilder)->createCommand()->rawSql);
exit();
Note that you should call it like that and not $model->user->... (the latter returns User instance).
But in your case it's not possible because count() immediately returns int. You can var_dump() partial query without count(), but I think it's not convenient.
Note that you can use this method for dumping generated SQL of any ActiveQuery instances (not only those that were returned by relation), for example:
$query = User::find()->where(['status' => User::STATUS_ACTIVE]);
var_dump($query->prepare(Yii::$app->db->queryBuilder)->createCommand()->rawSql);
exit();
Method 2
This is much simpler in my opinion and I personally prefer this one when debugging SQL queries.
Yii 2 has built-in debug module. Just add this to your config:
'modules' => [
'debug' => [
'class' => 'yii\debug\Module',
],
],
Make sure you only have it locally and not on production. If needed, also change allowedIPs property.
This gives you functional panel at the bottom of the page. Find the DB word and click on either count or time. On this page you can view all executed queries and filter them.
I usually don't filter them in Grid and use standard browser search to quickly navigate through and find the necessary query (using the table name as keyword for example).
Method 3
Just make an error in query, for example in column name - cityy instead of city. This will result as database exception and then you can instantly see the generated query in error message.
If you want to log all relational queries of ActiveRecord in console application all proposed methods don't help. They show only main SQL on active record's table, \yii\debug\Module works only in browser.
Alternative method to get all executed SQL queries is to log them by adding specific FileTarget to configuration:
'log' => [
'targets' => [[
...
], [
'class' => 'yii\log\FileTarget',
'logFile' => '#runtime/logs/profile.log',
'logVars' => [],
'levels' => ['profile'],
'categories' => ['yii\db\Command::query'],
'prefix' => function($message) {
return '';
}
]]
]
UPDATE
In order to log insert/update/delete queries one should also add yii\db\Command::execute category:
'categories' => ['yii\db\Command::query', 'yii\db\Command::execute']
you can try this, assume you have a query given like:
$query = new Books::find()->where('author=2');
echo $query->createCommand()->sql;
or to get the SQL with all parameters included try:
$query->createCommand()->getRawSql()
In addition to arogachev answer, when you already work with an ActiveQuery object, here is the line I search to view the rawsql.
/* #var $studentQuery ActiveQuery */
$studentQuery = Student::Find();
// Construct the query as you want it
$studentQuery->where("status=3")->orderBy("grade ASC");
// Get the rawsql
var_dump($studentQuery->prepare(Yii::$app->db->queryBuilder)->createCommand()->rawSql);
// Run the query
$studentQuery->all();
when you have a query object you can also use
$query->createCommand()->getRawSql()
to return the Raw SQL with the parameters included or
$query->createCommand()->sql
which will output the Sql with parameters separately.
In order to log/track every/all queries:
extend \yii\db\Connection and override createCommand method, like below:
namespace app\base;
class Connection extends \yii\db\Connection {
public function createCommand($sql = null, $params = array()) {
$createCommand = parent::createCommand($sql, $params);
$rawSql = $createCommand->getRawSql();
// ########### $rawSql -> LOG IT / OR DO ANYTHING YOU WANT WITH IT
return $createCommand;
}
}
Then, simply change your db connection in your db config like below:
'db' => [
'class' => 'app\base\Connection', // #### HERE
'dsn' => 'pgsql:host=localhost;dbname=dbname',
'username' => 'uname',
'password' => 'pwd',
'charset' => 'utf8',
],
Now, you can track/read/... all queries executed by db connection.
Try like,
$query = Yii::$app->db->createCommand()
->update('table_name', ['title' => 'MyTitle'],['id' => '1']);
var_dump($query->getRawSql()); die();
$query->execute();
Output:
string 'UPDATE `table_name`
SET `title`='MyTitle' WHERE `id`='1'
' (length=204)
I'm trying to update a row on my profiles table to reset a users profile picture to the default of user.png. I have the following action in my controller:
public function deleteProfilePicture() {
$this->layout = 'ajax';
// First find the profile ID from the user ID
$profileId = $this->Profile->find('first', array(
'condition' => array('User.id' => $this->Auth->user('id')),
'fields' => array('Profile.id'),
'recursive' => -1
));
$this->Profile->id = $profileId['Profile']['id'];
$this->Profile->saveField('picture', 'user.png', false);
}
However, when I request the URL (/profile/deleteProfilePicture) I get no errors but the database row isn't updated. I have made sure the current profile ID is used by using debug($profileId).
What could be going wrong here?
Edit: The return value of saveField():
array(
'Profile' => array(
'id' => '36',
'modified' => '2013-04-05 14:16:57'
)
)
Try
$this->Profile->id = $profileId['Profile']['id'];
$this->Profile->set(array(
'picture' => 'user.png'
));
$this->Post->save();
I see no error in your code. Try seeing what query is getting executed using this
$log = $this->Model->getDataSource()->getLog(false, false);
debug($log);
based on the result make changes to your query if you find something wrong.
Or try using this
$data['Profile']['id']=$profileId['Profile']['id'];
$data['Profile'['picture']='user.png';
$this->Profile->save($data);
If you set debug to 2 you could see what SQL is being executed, see if your update is actually firing.
Try this
$this->Profile->read(null, $profileId['Profile']['id']);
$this->Profile->saveField('picture', 'user.png', false);
Why are you setting the validation to false? Do you get an error if you omit that?
