How to get an array by Executing this query in Yii?
SELECT `sevrity_id`,COUNT(*) FROM `Incident` GROUP BY `sevrity_id`
I need an array like this: array(1=>20,2=10,3=12)
public function getSevrityCounts()
{
$data = array();
$command = Yii::app()->db->createCommand('SELECT sevrity_id,COUNT(*) AS num FROM Incident GROUP BY sevrity_id');
foreach($command->queryAll() as $row) {
$data[ $row['sevrity_id'] ] = $row['num'];
}
return $data;
}

i want use where for $query.
foreach ($oppId as $o) {
$id = $o['opportunity_id'];
$query->Where("id=$id");
}
When I use this. All items shown
$query->orWhere("id=$id");
i need get this query :
SELECT * FROM `opportunity` WHERE id =27 or id =28
this is all of my function :
public function actionShow($type = 0, $city = 0, $client = 0) {
$query = (new \yii\db\Query())->select(['*'])->from('opportunity ')->innerJoin('profile_details', 'opportunity.user_id=profile_details.user_id')->orderBy('id desc');
$query->Where('id !=-1');
if (isset($_REQUEST['type'])) {
$type = $_REQUEST['type'];
if ($type != 0) {
$query->andWhere("project_type_id=$type");
}
}
if (isset($_REQUEST['city'])) {
$city = $_REQUEST['city'];
if ($city != 0) {
$query->andWhere("state_id=$city");
}
}
if (isset($_REQUEST['client'])) {
$client = $_REQUEST['client'];
if ($client != 0) {
$oppId = \app\models\OpportunityControl::find()
->where('project_type_id = :project_type_id', [':project_type_id' => $client])
->all();
foreach ($oppId as $o) {
$id = $o['opportunity_id'];
$query->orWhere("id=$id");
}
}
}
You very much do not want to use strings to add to the query under any circumstances as that is ripe for SQL injection. I'd format it like this:
...
$params = [];
foreach ($oppId as $o) {
$params[] = $o->opportunity_id;
}
$query->andWhere(['in', 'id', $params]);
...
You should also adjust your other query params so that you are not passing variables into SQL via a string.
if (isset($_REQUEST['type'])) {
$type = $_REQUEST['type'];
if ($type != 0) {
$query->andWhere(['project_type_id' => $type]);
}
}
if (isset($_REQUEST['city'])) {
$city = $_REQUEST['city'];
if ($city != 0) {
$query->andWhere(['state_id' => $city]);
}
}
See the Yii2 guide on using variables in queries for what you are trying to avoid here. Specifically:
Do NOT embed variables directly in the condition like the following, especially if the variable values come from end user inputs, because this will make your application subject to SQL injection attacks.
// Dangerous! Do NOT do this unless you are very certain $status must be an integer.
$query->where("status=$status");
I do it with Arrays
$query->where(['or',['id'=>27],['id'=>28]]);
But in your case save all ids in a Array is not possible,I do it with string inside foreach
$StringWhere='';
$LastElement = end($oppId);
foreach ($oppId as $o)
{
$id = $o['opportunity_id'];
$StringWhere.=' id='.$id;
if($o!=$LastElement)
{
$StringWhere.=' or ';
}
}
$query->where($StringWhere);
$query->where(['or',['id'=>27],['id'=>28]]);
I use this and it works perfectly as mentioned by metola. :)
I've got this table
beds
id
name
size
room
status
hotel
created_at
updated_at
I need to filter all beds that belong to a certain room. In order to do so, I've coded this lines.
public function index()
{
//
$user = JWTAuth::parseToken()->authenticate();
$data = Input::get('room');
if( $data ){
$beds = Bed::where('room', '=', $data )->get();
}else{
$beds = Bed::where('hotel', '=', $user->hostel )->get();
}
foreach( $beds as $bed) {
return $bed->get( array('size','room', 'id') );
}
}
So, If i give it the room id, it should return me only that room's ones.
The thing is that it's returning all table entries.
Any ideas?
UPDATE
Fixed relations and tried this:
return Room::with('beds')->findOrFail($data)->beds;
Now it gives me the number of items.
How can I get the items?
UPDATE
This is the model's code:
class Room extends \Eloquent {
protected $fillable = array('beds', 'price', 'name', 'description','hotel');
public function beds(){
return $this->hasMany('Bed', 'id', 'room');
}
}
UPDATE
The var_dump for:
var_dump( Room::with('beds')->findOrFail($data)->beds );
is:
int(1)
UPDATE
So, the final code is the following.
controller
public function index()
{
//
$user = JWTAuth::parseToken()->authenticate();
$data = Input::get('room');
if( $data ){
$d = intval( $data );
return Bed::where('room', '=', $d )->get( array('size', 'room', 'id', 'name') );
}else{
return Bed::where('hotel', '=', $user->hostel )->get( array('size', 'room', 'id', 'name') );
}
}
model
class Room extends \Eloquent {
protected $fillable = array('beds', 'price', 'name', 'description','hotel');
public function camas(){
return $this->hasMany('Bed', 'room', 'id');
}
}
Thank you guys!
You have quite a few issues in your attempts:
return $bed->get( array('size', 'room', 'id') );
// runs SELECT size, room, id from `rooms`
so it returns all the rooms (why on earth would you like to do this in a foreach anyway?)
return $this->hasMany('Bed', 'id', 'room');
// should be:
return $this->hasMany('Bed', 'room', 'id');
protected $fillable = array('beds', ...
public function beds(){
this is conflict - you will never get a relations when calling $room->beds since you have a column beds on your table.
that said, this is what you need:
public function index()
{
$user = JWTAuth::parseToken()->authenticate();
if(Input::has('room')){
$query = Bed::where('room', '=', Input::get('room'));
}else{
$query = Bed::where('hotel', '=', $user->hostel);
}
return $query->get(['size', 'room', 'id']); // given you need only these columns
}
Try this and see if it works. If not, can you provide the var_dump of Input::get('room') and the structure of the the beds table?
public function index()
{
//
$user = JWTAuth::parseToken()->authenticate();
$data = Input::get('room');
if( $data ){
$beds = Bed::where('room', '=', $data );
}else{
$beds = Bed::where('hotel', '=', $user->hostel );
}
return $beds->get(['size','room', 'id'])->toArray();
}
Better yet if you want to get specific beds in a room and you have your relations set up correctly:
return Room::with('beds')->findOrFail($data)->beds;
EDIT
I saw your update. Are you sure its giving you a number of items, maybe there is one item and the number is the id of it. Can you verify? Please provide a vardump of it if thats not the case. Also can you post your code for the relations in the model?
I am trying to create an array containing results from an SQL table. But my foreach loop does not appear to be function correctly.
Here is my code:
$stmt->bind_param("i", $id);
$stmt->execute();
while ($stmt->fetch()) {
}
$stmt->close();
$i = 0;
foreach ($connected_items as &$value) {
print_r ($connected_items[$i]);
$stmt->bind_param("i", $connected_items[$i]);
$stmt->execute();
while ($stmt->fetch()) {
$result[] = array(,
);
}
$stmt->close();
$i++;
}
unset($value);
)
)
It appears to be running the for loop on my print statement and then MySQL statement, using the last connected_items_id, why is that? And why is it not returning the associated values for that id?
remove this [] at line number 6:
while ($stmt->fetch()) {
$connected_items = array($connected_items_id);
}
instead of this:
while ($stmt->fetch()) {
$connected_items[] = array($connected_items_id);
}
Try this,
"connected_item_id" => $connected_items[0],
instead of
"connected_item_id" => $connected_items_id,
Try
foreach ($connected_items as $value) {
......................
......................
$stmt = $this->db->prepare('SELECT name, serial FROM `glpi_monitors` WHERE id =?');
$stmt->bind_param("i", $value[0]);
................................
................................
}
Also you can use IN keyword instead of looping and querying each time.
$sql = "SELECT name, serial FROM `glpi_monitors` WHERE id IN('".implode("','",$connected_items)."'");
$stmt = $this->db->prepare($sql);
eg :
Is it possible to extract raw sql query from the query builder instance in Phalcon? Something like this?
$queryBuilder = new Phalcon\Mvc\Model\Query\Builder();
$queryBuilder
->from(…)
->where(…);
$rawSql = $queryBuilder->hypotheticalGetRawQueryMethod();
By error and trial the below seems to working. Would be great if someone could confirm if there's a better way.
$queryBuilder = new Builder();
$queryBuilder->from(…)->where(…);
$intermediate = $queryBuilder->getQuery()->parse();
$dialect = DI::getDefault()->get('db')->getDialect();
$sql = $dialect->select($intermediate);
Edit: As of 2.0.3 you can do it super simple, see comment for full details:
$modelsManager->createBuilder()
->from('Some\Robots')
->getQuery()
->getSql()
you can use getRealSqlStatement() (or similar function name) on the DbAdapter. See http://docs.phalconphp.com/en/latest/api/Phalcon_Db_Adapter.html
According to documentation you can get this way the resulting sql query.
Or wait, this might not work on querybuilder. Otherwise you can setup low level query logging: http://docs.phalconphp.com/en/latest/reference/models.html#logging-low-level-sql-statements
$db = Phalcon\DI::getDefault()->getDb();
$sql = $db->getSQLStatement();
$vars = $db->getSQLVariables();
if ($vars) {
$keys = array();
$values = array();
foreach ($vars as $placeHolder=>$var) {
// fill array of placeholders
if (is_string($placeHolder)) {
$keys[] = '/:'.ltrim($placeHolder, ':').'/';
} else {
$keys[] = '/[?]/';
}
// fill array of values
// It makes sense to use RawValue only in INSERT and UPDATE queries and only as values
// in all other cases it will be inserted as a quoted string
if ((strpos($sql, 'INSERT') === 0 || strpos($sql, 'UPDATE') === 0) && $var instanceof \Phalcon\Db\RawValue) {
$var = $var->getValue();
} elseif (is_null($var)) {
$var = 'NULL';
} elseif (is_numeric($var)) {
$var = $var;
} else {
$var = '"'.$var.'"';
}
$values[] = $var;
}
$sql = preg_replace($keys, $values, $sql, 1);
}
More you can read there
The following is the common solution:
$result = $modelsManager->createBuilder()
->from(Foo::class)
->where('slug = :bar:', ['bar' => "some-slug"])
->getQuery()
->getSql();
But you might not expect to see the query without its values, like in:
die(print_r($result, true));
Array
(
[sql] => SELECT `foo`.`id`, `foo`.`slug` FROM `foo` WHERE `foo`.`slug` = :bar
[bind] => Array
(
[bar] => some-slug
)
[bindTypes] =>
)
So, this simple code might be useful:
public static function toSql(\Phalcon\Mvc\Model\Query\BuilderInterface $builder) : string
{
$data = $builder->getQuery()->getSql();
['sql' => $sql, 'bind' => $binds, 'bindTypes' => $bindTypes] = $data;
$finalSql = $sql;
foreach ($binds as $name => $value) {
$formattedValue = $value;
if (\is_object($value)) {
$formattedValue = (string)$value;
}
if (\is_string($formattedValue)) {
$formattedValue = sprintf("'%s'", $formattedValue);
}
$finalSql = str_replace(":$name", $formattedValue, $finalSql);
}
return $finalSql;
}
If you're using query builder then like given below then getPhql function can serve the purpose as per phalcon 3.4.4 version.
$queryBuilder = new Builder();
$queryBuilder->from(…)->where(…)->getQuery();
$queryBuilder->getPhql();
if (!function_exists("getParsedBuilderQuery")) {
/**
* #param \Phalcon\Mvc\Model\Query\BuilderInterface $builder
*
* #return null|string|string[]
*/
function getParsedBuilderQuery (\Phalcon\Mvc\Model\Query\BuilderInterface $builder) {
$dialect = Phalcon\Di::getDefault()->get('db')->getDialect();
$sql = $dialect->select($builder->getQuery()->parse());
foreach ($builder->getQuery()->getBindParams() as $key => $value) {
// For strings work fine. You can add other types below
$sql = preg_replace("/:?\s?($key)\s?:?/","'$value'",$sql);
}
return $sql;
}
}
Simple function that im using for debugging.
I am starting with Zend Framework 2 , I want to make a routing choice with the role of My user and I must write getRoleByID($id) ,
then
How can'I write
" Select 'role' from user where ('id' = $id) " with Zend\Db\Sql
Example Using Select:
$select = new \Zend\Db\Sql\Select('user');
$select->columns(array('role'));
$where = new Where();
$where->equalTo('id', $id);
$select->where($where);
/**
* Simple example of executing a query...
*/
$stmt = $this->getSql()->prepareStatementForSqlObject($select);
$results = $stmt->execute();
/* #var $results \Zend\Db\Adapter\Driver\Pdo\Result */
if( ! $results->count()) {
// do something, none found...
}
$row = $results->current();
return $row['role'];
// if you had multiple results to iterate over:
//$resultSet = new \Zend\Db\ResultSet\ResultSet();
//$resultSet->initialize($results);
//$array = $resultSet->toArray();
//foreach($resultSet as $row) { /* ... */ }
