Symfony2/Doctrine QueryBuilder using andwhere() - doctrine

I am using following method in a repository class to look for certain tags in my database:
public function getItemsByTag($tag, $limit = null)
{
$tag = '%'.$tag.'%';
$qb = $this->createQueryBuilder('c');
$qb->select('c')
->where($qb->expr()->like('c.tags', '?1'))
->setParameter(1, $tag)
->addOrderBy('c.clicks', 'DESC');
if (false === is_null($limit))
$qb->setMaxResults($limit);
return $qb->getQuery()->getResult();
}
This works just nice.. But: How can I add 2 additional variables (where: reviewed = 1, enabled = 1)? I tried andwhere() but I couldn't figure it out.
I also found out that something like this:
public function getItems($limit = null)
{
$qb = $this->createQueryBuilder('b')
->select('b')
->add('where', 'b.reviewed = 1')
->add('where', 'b.enabled = 1')
->addOrderBy('b.name', 'ASC');
// ...
}
won't work either...
Any hints?

I would write it like this:
$qb = $this
->createQueryBuilder('c')
->where('c.tags LIKE :tag')
->andWhere('c.reviewed = 1')
->andWhere('c.enabled = 1')
->setParameter('tag', "%{$tag}%")
->orderBy('c.clicks', 'DESC')
->addOrderBy('b.name', 'ASC');
if ($limit) {
$qb->setMaxResults($limit);
}
return $qb->getQuery()->getResult();
You could also unite those where conditions:
->where('c.tags LIKE :tag AND c.reviewed = 1 AND c.enabled = 1')

From the manual, the suggested way is like below:
$qb->select(array('c'))
->where($qb->expr()->orx(
$qb->expr()->eq('c.reviewed', 1),
$qb->expr()->eq('c.enabled', 1),
$qb->expr()->like('c.tags', '?1')
))
->orderBy('c.clicks', 'DESC'));

Laravel: how to check if array is empty or not?

let's say i have this query:
$schedules = [33,34];
foreach ($schedules as $schedule) {
$buses[] = DB::table("buses")->select('id', 'bus_number')
->where('station_id', $stations_id)
->whereNotNull('Driver_id')
->get();
}
The data it is returning is empty like this: [[],[]]
So, my question Is how to check if there is data in it or not?
A simple solution would be excluding null filled values:
$schedules = [33,34];
foreach ($schedules as $schedule) {
$bus = DB::table("buses")->select('id', 'bus_number')
->where('station_id', $stations_id)
->whereNotNull('Driver_id')
->get();
if($bus && isset($bus->id)) {
$buses[] = $bus;
}
}
if($buses && count($buses)>0) {
//has value
}
If you have related Schedule with buses, you could use, something like this;
$schedules = Schedule::whereIn('id',$schedule_ids)->with('buses')->get();
//and you dont need to set into an array
You could use count() funcion, something like this:
$schedules = [33,34];
foreach ($schedules as $schedule) {
$bus = DB::table("buses")->select('id', 'bus_number')
->where('station_id', $stations_id)
->whereNotNull('Driver_id')
->get();
if(count($buses) > 0) {
$buses[] = $bus;
}
}

Codeigniter count_all_results with having

I have composed a query using Codeigniter's Query Builder class. The query utilizes aliases and the having method. When I call the count_all_results method on this query, an exception occurs. Inspecting the log, I see that the query has stripped out the 'having' clauses. Is there a way to keep these clauses in while calling count_all_results? Thanks for your help.
EDIT: I first believed the problem was knowledge-based and not code-based and so did not share the code, but here it is. Please let me know if more is needed.
Here's the call on the model in the controller.
$where_array = array(
$parent_key.' is not NULL' => null
);
$search_post = $request_data['search'];
if (isset($request_data['filter'])) {
$filter_array = $request_data['filter'];
foreach ($filter_array as $filter_pair) {
if (isset($filter_pair['escape'])) {
$where_array[$filter_pair['filterBy']] = null;
} else {
if ($filter_pair['filterBy'] == 'table3_id') {
$where_array['table3.'.$filter_pair['filterBy']] = isset($filter_pair['filterId']) ?
$filter_pair['filterId'] : null;
} else {
$where_array[$table.'.'.$filter_pair['filterBy']] = isset($filter_pair['filterId']) ?
$filter_pair['filterId'] : null;
}
}
}
}
$like_array = array();
foreach ($request_data['columns'] as $key => $column) {
if (!empty($column['search']['value'])) {
$like_array[$column['data']] = $column['search']['value'];
}
}
$totalFiltered = $this->$model_name->modelSearchCount($search, $where_array, $like_array);
Here's the model methods.
public function modelSearchCount($search, $where_array = null, $like_array = null)
{
$this->joinLookups(null, $search);
if ($where_array) {
$this->db->where($where_array);
}
if ($like_array) {
foreach($like_array as $key => $value) {
$this->db->having($key." LIKE '%". $value. "%'");
}
}
return $this->db->from($this->table)->count_all_results();
}
protected function joinLookups($display_config = null, $search = null)
{
$select_array = null;
$join_array = array();
$search_column_array = $search ? array() : null;
$i = 'a';
$config = $display_config ? $display_config : $this->getIndexConfig();
foreach ($config as $column) {
if (array_key_exists($column['field'], $this->lookups)) {
$guest_model_name = $this->lookups[$column['field']];
$this->load->model($guest_model_name);
$join_string =$this->table.'.'.$column['field'].'='.$i.'.'.
$this->$guest_model_name->getKey();
$guest_display = $this->$guest_model_name->getDisplay();
if ($search) {
$search_column_array[] = $i.'.'.$guest_display;
}
$join_array[$this->$guest_model_name->getTable().' as '.$i] = $join_string;
$select_array[] = $i.'.'.
$guest_display;
} else {
$select_array[] = $this->table.'.'.$column['field'];
if ($search) {
$search_column_array[] = $this->table.'.'.$column['field'];
}
}
$i++;
}
$select_array[] = $this->table.'.'.$this->key;
foreach ($join_array as $key => $value) {
$this->db->join($key, $value, 'LEFT');
}
$this->db->join('table2', $this->table.'.table2_id=table2.table2_id', 'LEFT')
->join('table3', 'table2.table3_id=table3.table3_id', 'LEFT')
->join('table4', $this->table.'.table4_id=table4_id', 'LEFT')
->join('table5', 'table4.table5_id=table5.table5_id', 'LEFT');
$this->db->select(implode($select_array, ', '));
if ($search) {
foreach (explode(' ', $search) as $term) {
$this->db->group_start();
$this->db->or_like($this->table.'.'.$this->key, $term);
foreach ($search_column_array as $search_column) {
$this->db->or_like($search_column, $term);
}
$this->db->group_end();
}
}
$this->db->select('table2_date, '. $this->table.'.table2_id, table4_id, '. 'table5.table5_description');
}
Since count_all_results() will basically run a Select count(*) and not count the rows in your resultset (basically rendering the query useless for your purposes) you may use other Codeigniter methods to get the resultset and the row count.
Try running the query into a variable:
$query = $this->db->get();
From then, you can do pretty much anything. Besides returning the result with $query->result(); you can get the number of rows into another variable with:
$rownum = $query->num_rows();
You can then return that into your controller or even just return the $query object and then run the num_rows() method on the controller
To answer this question, count_all_results() transforms the original query by replacing your selects with SELECT COUNT(*) FROM table. the aliased column would not be selected, and the having clause would not recognize the column. This is why count_all_results() does not work with having.

Laravel: dynamic where clause with Elouquent

I am calling URL with search params which are dynamic. How could I form proper Eloquent query?
In theory:
query
query where(someParam1)
query where(someParam2)
query orderby(someParam3)
query get
I need this kind of structure so I can use where clause if param exists.
If there is some other way in Laravel, please let me know.
It's easy with Laravel. Just do something like this:
$query = User::query();
if ($this == $that) {
$query = $query->where('this', 'that');
}
if ($this == $another_thing) {
$query = $query->where('this', 'another_thing');
}
if ($this == $yet_another_thing) {
$query = $query->orderBy('this');
}
$results = $query->get();
You can just use the where statement.
For ex: on users table or User model, you want dynamic search on name, id. You can do this
$where = [];
$firstName = $request->get('first_name');
if ($firstName) $where[] = ['first_name', 'like'. '%' . $firstName . '%'];
$id = $request->get('id');
if ($id) $where[] = ['id', $id];
$users = User::where($where)->get();
By default, it will return all the users, if anything exists in $where array, it will apply the where condition on that.
You can use like this
$validateUserDetail = User::query();
if (!empty($userDetails['email'])) {
$validateUserDetail->whereemail($userDetails['email']);
}if (!empty($userDetails['cellphone'])) {
$validateUserDetail->wherecellphone($userDetails['cellphone']);
}
$validateUserDetail->select('username');
$validateUserDetail->get()
You can pass dynamic value by below example
$user_auctions = $this->with('userAuctions')
->where('users.id', '=', $id)
->get();
I came here from Google. If you are going to be iterating over more then 5 if statements, its more effective to use a switch statement
if(empty($request->except('_token')))
return 'false';
$models = Vehicle::query();
$request_query = $request->all();
$year_switch = false;
foreach ($request_query as $key => $field_value){
if($field_value != 'any'){
switch($field_value){
case 'X':
case 'Y':
$year_switch = true;
break;
case'Z':
//Dynamic
$models->where($key,'LIKE', $field_value);
break;
}
}
}
You can pass a callback to the where function.
So, you can do something like this:
class TestService {
TestRepository $testeRepository;
public function __construct(TesteRepository $teste) {
$this->testeRepository = $teste;
}
public function getAll(array $filters)
{
$where = function (Builder $query) use ($filters) {
collect($filters)
->each(function ($value, $param) use ($query) {
if ($param === 'test') {
$query->where($param, '=', $value);
} else if ($param === 'test2') {
$query->orWhere($param, '>', $value);
}
});
};
return $this->testRepository->gelAll($where);
}
class TestRepository
{
public function getAll(\Closure $where)
{
$query = TestModel::query();
$query->where($where);
//and put more stuff here, like:
//$query->limit(15)->offset(30)
...
return $query->get();
}
}
And in your controller you pass the filters:
class TestControler ...
{
public function $index()
{
$filters = request()->query();
return $this->testService->getAll($filters);
}
}

Laravel how to get query with bindings?

I have some query that I need to pass to another query using query builder
$query = DB::table('table')->whereIn('some_field', [1,2,30])->toSql();
Model::join(DB::raw("({$query}) as table"), function($join) {
$join->on('model.id', '=', 'table.id');
})
which should results with
Select * from model join (select * from table where some_field in (1,2,30)) as table on model.id = table.id
but the bindings are not passed, which force me to do
$query = DB::table('table')->whereRaw('some_field in ('. join(',', [1,2,30]) .')')->toSql();
what can be unsafe at times. How can I get the query with bindings?
Check out the getBindings() method on the Builder class
getBindings()
$query = DB::table('table')->whereIn('some_field', [1,2,30]);
$sql = $query->toSql();
$bindings = $query->getBindings();
Laravel now offers debugging directly on your Builder!!!
https://laravel.com/docs/queries#debugging
\App\User::where('age', '18')->dump();
\App\User::where('age', '18')->dd();
Outputs
"select * from `users` where `age` = ?"
[
0 => "18"
]
public static function getQueries(Builder $builder)
{
$addSlashes = str_replace('?', "'?'", $builder->toSql());
return vsprintf(str_replace('?', '%s', $addSlashes), $builder->getBindings());
}
You can define below code block as helper function and use wherever required.
It will bind numeric as well as string value with quotations.
public static function getSqlWithBindings($query)
{
return vsprintf(str_replace('?', '%s', $query->toSql()), collect($query->getBindings())->map(function ($binding) {
return is_numeric($binding) ? $binding : "'{$binding}'";
})->toArray());
}
Example:
$query = Document::where('model', 'contact')->where('model_id', '1');
dd(Document::getSqlWithBindings($query));
Output:
"select * from `document` where `model` = 'contact' and `model_id` = 1"
Building upon Douglas.Sesar's answer.
I found I also needed to put the bindings in single quotations to be able to easily paste it into my database IDE.
$sql = $query->toSql();
$bindings = $query->getBindings();
$sql_with_bindings = preg_replace_callback('/\?/', function ($match) use ($sql, &$bindings) {
return json_encode(array_shift($bindings));
}, $sql);
$sqlQuery = Str::replaceArray(
'?',
collect($query->getBindings())
->map(function ($i) {
if (is_object($i)) {
$i = (string)$i;
}
return (is_string($i)) ? "'$i'" : $i;
})->all(),
$query->toSql());
The following function ensures the resulting SQL doesn't confuse bindings with columns by enclosing the ? to be '?'
public static function getFinalSql($query)
{
$sql_str = $query->toSql();
$bindings = $query->getBindings();
$wrapped_str = str_replace('?', "'?'", $sql_str);
return str_replace_array('?', $bindings, $wrapped_str);
}
If you want to get an executed query including bindings from the query log:
\DB::enableQueryLog();
\DB::table('table')->get();
dd(str_replace_array('?', \DB::getQueryLog()[0]['bindings'],
\DB::getQueryLog()[0]['query']));
I created this function. It is partial, might be parameters which are not covered, for me it was enough.
More than welcomed to add your improvements in a comment!
function getFullSql($query) {
$sqlStr = $query->toSql();
foreach ($query->getBindings() as $iter=>$binding) {
$type = gettype($binding);
switch ($type) {
case "integer":
case "double":
$bindingStr = "$binding";
break;
case "string":
$bindingStr = "'$binding'";
break;
case "object":
$class = get_class($binding);
switch ($class) {
case "DateTime":
$bindingStr = "'" . $binding->format('Y-m-d H:i:s') . "'";
break;
default:
throw new \Exception("Unexpected binding argument class ($class)");
}
break;
default:
throw new \Exception("Unexpected binding argument type ($type)");
}
$currentPos = strpos($sqlStr, '?');
if ($currentPos === false) {
throw new \Exception("Cannot find binding location in Sql String for bundung parameter $binding ($iter)");
}
$sqlStr = substr($sqlStr, 0, $currentPos) . $bindingStr . substr($sqlStr, $currentPos + 1);
}
$search = ["select", "distinct", "from", "where", "and", "order by", "asc", "desc", "inner join", "join"];
$replace = ["SELECT", "DISTINCT", "\n FROM", "\n WHERE", "\n AND", "\n ORDER BY", "ASC", "DESC", "\n INNER JOIN", "\n JOIN"];
$sqlStr = str_replace($search, $replace, $sqlStr);
return $sqlStr;
}
You can do something like this:
$escapedBindings = array();
foreach($query->getBindings() as $item) {$escapedBindings[] = '"'.$item.'"';}
$sql_with_bindings = Str::replaceArray('?', $escapedBindings, $query->toSql());
This is a very old question (2015), but since this is the first Google result I got I think it's worth to give my solution as well, in case it's useful for the next person.
Eloquent (5.7 onwards I think, I haven't tested more recent or earlier versions) has a method to change a Builder's from to wrap a subquery:
# Taken from Illuminate/Database/Query/Builder.php - Line 272
public function fromSub($query, $as) {
[$query, $bindings] = $this->createSub($query);
return $this->fromRaw('('.$query.') as '.$this->grammar->wrapTable($as), $bindings);
}
This however requires an already existing instance of \Illuminate\Database\Query\Builder. In order to make an empty one, you can do:
use Illuminate\Database\Capsule\Manager as DB;
$fancy = DB::table("videogames")->where("uses_sdl2", 1);
$empty = DB::table(null);
# Wrap the fancy query and set it as the "from" clause for the empty one
# NOTE: the alias is required
$empty = $empty->fromSub($fancy, "performant_games");
This will warranty that bindings are treated correctly, since they'll be handled by Eloquent itself.
Since the other answers do not properly quote the expressions, here is my approach. It uses the escaping function that belongs to the current database connection.
It replaces the question marks one by one with the corresponding binding, which is retrieved from $bindings via array_shift(), consuming the array in the process. Note, that $bindings has to be passed by reference for this to work.
function getSql($query)
{
$bindings = $query->getBindings();
return preg_replace_callback('/\?/', function ($match) use (&$bindings, $query) {
return $query->getConnection()->getPdo()->quote(array_shift($bindings));
}, $query->toSql());
}
Simple and elegant solution:
foreach (DB::getQueryLog() as $q) {
$queryStr = \Str::replaceArray('?', $q['bindings'], $q['query']);
echo $queryStr . ";\n";
}
(if you use a non-default connection, use DB::connection('yourConn')->getQueryLog() in the foreach command).
Output to the log all queries with inserted bindings sorted from the slowest query to the fastest:
\DB::enableQueryLog();
// Put here your queries
$query = DB::table('table')->whereIn('some_field', [1,2,30]);
$query2 = DB::table('table2')->where('some_field', '=', 10);
$logQueries = \DB::getQueryLog();
usort($logQueries, function($a, $b) {
return $b['time'] <=> $a['time'];
});
foreach ($logQueries as $item) {
\Log::info(str_replace_array('?', $item['bindings'], $item['query']));
\Log::info($item['time']. ' ms');
}
It is all explained here.....
https://ajcastro29.blogspot.com/2017/11/laravel-join-derived-tables-properly.html
I created a scope query for that thing. I think it can also be in macros..
public function scopeJoinDerived($query, $derivedQuery, $table, $one, $operator = null, $two = null, $type = 'inner', $where = false)
{
$query->join(DB::raw("({$derivedQuery->toSql()}) as `{$table}`"), $one, $operator, $two, $type, $where);
$join = last($query->getQuery()->joins);
$join->bindings = array_merge($derivedQuery->getBindings(), $join->bindings);
return $query;
}

Laravel Operators AND / && - How to Use Them?

I am trying to use AND as well as && in this code block:
public function show($id)
{
$user = Auth::user()->id;
$userEmail = Auth::user()->email;
$share = Share::where('sbj_id', $id)->first();
if ($share->sbj_id == $id && $share->email == $userEmail ) {
$items = Item::where('project_id', $id)
->orderBy("created_at", "desc")
->groupBy('label_name')
->get();
$sbj = Sbj::find($id);
$allSbj = Sbj::where('user_id', $user)->orderBy("created_at", "desc")->get();
$labels = Label::all();
$pages = Page::where('project_id', $id)->orderBy('created_at', 'desc')->get();
$people = Friend::where('sbj_id', $id)->orderBy("created_at", "desc")->get();
$myPeeps = Contact::where('my_id', $user)->get();
return View::make('sbjs.show', compact('sbj', 'pages', 'labels', 'people', 'myPeeps', 'allSbj', 'items'));
} else {
return Redirect::action ('SbjsController#index');
}
}
However, I am looking online to see if && or AND is supported in Lavavel in this context but no success. My app is taking the user to the ELSE action.
Any ideas?
I just added the Eloquent statement to the IF conditional and it worked fine...not sure why it was not evaluating.
