i have an custom extension, where you can select the different entries at the backend, to show them at the list view. I have a custom sorting at my backend, but the system always sort them Descending.
I implemented an "orderBy" function, which doesnt work, because the system uses wrong backspaces.
My code looks like this:
I call the sort function in my "findByUid($uid)" function like this:
$query->setOrderings($this->orderByKey('uid', $uidArray));
protected function orderByKey($key, $uidlist) {
$order = array();
foreach ($uidlist as $uid) {
//$order["$key=$uid"] = \TYPO3\CMS\Extbase\Persistence\QueryInterface::ORDER_DESCENDING;
$order["$key=$uid"] = "ASC";
\TYPO3\CMS\Extbase\Utility\DebuggerUtility::var_dump($order);
}
return $order;
}
The result at the sql query is:
ORDER BY `tx_MYEXTENSION_domain_model_FIELD`.`uid=3` DESC
But it must be:
ORDER BY `tx_MYEXTENSION_domain_model_FIELD`.`uid` = 3 DESC
Is there a way to change this?
After a lot of search, I found this solution on an stackoverflow entry:
$ids = explode(',',$this->settings['entries'])
foreach($ids as $key => $id){
$entries[$id] = $this->entriesRepository->findByUid($id);
}
This code snippet has to be intergrated at the controller.
For me its working.

I have written this SQL code
SELECT drugs.*, COUNT(*) as 'views' from drugs INNER JOIN drug_seen on drugs.id = drug_seen.drug_id GROUP BY drugs.id order by views ASC
And now I am trying to write in in the Laravel equolent but I am facing some troubles.
This is what I have tried
$drugs = Drug::select(DB::raw('drugs.*,count(*) as views'))
->join('drug_seen', 'drugs.id', 'drug_seen.drug.id')
->groupBy('drug.id')->orderByRaw('views');
I am having errors like column not found i think the code is not written properly
Drug class
class Drug extends Model
{
use HasFactory;
use SoftDeletes;
...
...
...
public function drugVisits()
{
return $this->hasMany(DrugSeen::class);
}
Hop this will solve your problem.
$drugs = Drug::with('drugVisits')->get();
$drugs->count(); //for total records in drugs table.
You have typo error in join instead on drug_id you use drug.id
Try this:
$drugs = Drug::select(DB::raw('drugs.*,count(*) as views'))
->join('drug_seen', 'drugs.id', 'drug_seen.drug_id')
->groupBy('drugs.id')->orderByRaw('views');
}
As soon as you use join() you're leaving Eloquent and entering Query\Builder, losing the benefits of Model configurations in the process. And with() eager-loads aren't the answer, if you're looking to filter the results by both tables. What you want is whereHas().
Also, as far as your grouping and count manipulation there, I think you're looking more for Collection handling than SQL groups.
$drugModel = app(Drugs::class);
$results = $drugModel->whereHas('drugVisits')->with('drugVisits')->get();
$organizedResults = $results
->groupBy($drugModel->getKey())
->sortyBy(function (Drugs $drugRecord) {
return $drugRecord->drugVisits->count();
});
If you want to have a 'views' property that carries the count in the root-level element, it would look like this:
$drugModel = app(Drugs::class);
$results = $drugModel->whereHas('drugVisits')->with('drugVisits')->get();
$organizedResults = $results
->groupBy($drugModel->getKey())
->map(function (Drugs $drugRecord) {
$drugRecord->views = $drugRecord->drugVisits->count();
return $drugRecord;
});
->sortyBy('views');
I have a codeigniter app.
My active record syntax works perfectly and is:
function get_as_09($q){
$this->db->select('m3');
$this->db->where('ProductCode', $q);
$query = $this->db->get('ProductList');
if($query->num_rows > 0){
foreach ($query->result_array() as $row){
$row_set[] = htmlentities(stripslashes($row['m3'])); //build an array
}
return $row_set;
}
}
This is effectively
select 'm3' from 'ProductList' where ProductCode='$1'
What I need to do is convert the below query into an active record type query and return it to the controller as per above active record syntax:
select length from
(SELECT
[Length]
,CONCAT(([width]*1000),([thickness]*1000),REPLACE([ProductCode],concat(([width]*1000),([thickness]*1000),REPLACE((convert(varchar,convert(decimal(8,1),length))),'.','')),'')) as options
FROM [dbo].[dbo].[ProductList]) as p
where options='25100cr' order by length
I picture something like below but this does not work.
$this->db->select(length);
$this->db->from(SELECT [Length],CONCAT(([width]*1000),([thickness]*1000),REPLACE[ProductCode],concat(([width]*1000),([thickness]*1000),REPLACE((convert(varchar,convert(decimal(8,1),length))),'.','')),'')) as options
FROM [dbo].[dbo].[ProductList]);
$this->db->where(options, $q);
$this->db->order(length, desc);
Help appreciated as always. Thanks again.
You can use sub query way of codeigniter to do this for this purpose you will have to hack codeigniter. like this
Go to system/database/DB_active_rec.php Remove public or protected keyword from these functions
public function _compile_select($select_override = FALSE)
public function _reset_select()
Now subquery writing in available And now here is your query with active record
$select = array(
'Length'
'CONCAT(([width]*1000)',
'thickness * 1000',
'REPLACE(ProductCode, concat((width*1000),(thickness*1000),REPLACE((convert(varchar,convert(decimal(8,1),length))),'.','')),'')) as options'
);
$this->db->select($select);
$this->db->from('ProductList');
$Subquery = $this->db->_compile_select();
$this->db->_reset_select();
$this->db->select('length');
$this->db->from("($Subquery)");
$this->db->where('options','25100cr');
$this->db->order_by('length');
And the thing is done. Cheers!!!
Note : While using sub queries you must use
$this->db->from('myTable')
instead of
$this->db->get('myTable')
which runs the query.

I'm trying to do a query where I preserve the order of the ids in a IN statement. I can't seem to do it with either the Model Manage Query Builder or the standard ORM 'order' array parameter. Am I missing something? I keep getting:
UNEXPECTED TOKEN IDENTIFIER(, NEAR TO 'id`enter code here`,17743,16688,16650
Here's my model manager:
$query = $this->modelsManager->createQuery('SELECT * FROM Projects WHERE id IN ('.implode(',', array_keys($finalIterations)).')
ORDER BY FIELD(id,'.implode(',', array_keys($finalIterations)).'');
It's pretty obvious PhQL doesn't like the FIELD key word. Is there a way for me to do what I'm trying to do with PhQL? It seems I will not be able to do what I need to.
Unfortunately as previously said, this is missing a feature in Phalcon.
Have a look at this function, I've put it into my ModelBase abstract class which is parent class of all my models. It uses PhQL variable binding, so it's safe for handling direct user input.
You could have reimplemented custom \Phalcon\Mvc\Model\Criteria but this solution seems to be easier to work with, at least for me.
ModelBase abstract
public function appendCustomOrder( \Phalcon\Mvc\Model\CriteriaInterface &$criteria, $orderField, array &$orderValues = [] ) {
if(!empty($orderValues)) {
$queryKeys = $bindParams = [];
foreach($orderValues as $key => $id) {
$queryKey = 'pho'.$key;
$queryKeys[] = ':'.$queryKey.':';
$bindParams[$queryKey] = $id;
}
// TODO: add support for multiple orderBy fields
$criteria->orderBy('FIELD('.$orderField.','.implode(',',$queryKeys).')');
// there's no 'addBind' function, need to merge old parameters with new ones
$criteria->bind( array_merge( (array) #$criteria->getParams()['bind'], $bindParams ) );
}
}
Controller usage
$projectIDs = [17743, 16688, 16650];
$projectsModel = new Projects();
$criteria = $projectsModel->query->inWhere( 'id', $projectIDs );
$projectsModel->appendCustomOrder( $criteria, 'id', $projectIDs );
$projectsData = $criteria->execute();
This will generate valid PhQL syntax similar to this one:
SELECT `projects`.`id` AS `id`, `projects`.`title` AS `title`
FROM `projects`
WHERE `projects`.`id` IN (:phi0, :phi1, :phi2)
ORDER BY FIELD(`projects`.`id`, :pho0, :pho1, :pho2)
i want to get some database tables from my typo3 extensions.
The Extension is based on extbase.
The query always returns nothing but the data exists
I've tried this:
$query = $this->createQuery();
$query->statement('SELECT * FROM `my_table`
WHERE field = ? ORDER BY date DESC LIMIT 1',
array($condition));
$results = $query->execute();
and this:
$query = $this->createQuery();
$query->matching($query->equals('field', $condition));
$query->setOrderings(array('date' => Tx_Extbase_Persistence_QueryInterface::ORDER_DESCENDING));
$query->setLimit(1);
$results = $query->execute();
both returns null as result.
Is it possible to get the sql that the class creates to look where the bug is?
I've looked in some extbase persistent classes but didn't find a clue
EDIT:
For those who are interested.. i found a "solution".
If you create the query with the statement() method, you can print the query with this function
echo $query->getStatement()->getStatement();
It doesn't replace the placeholder.
But you can get the Variables with this method
var_dump($query->getStatement()->getBoundVariables());
Thats the best Solution that i found, without editing the extbase extenstions
In TYPO3 6.2 you can use Extbase DebuggerUtility to debug the query.
Add this code before $query->execute():
$queryParser = \TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance('TYPO3\\CMS\\Extbase\\Persistence\\Generic\\Storage\\Typo3DbQueryParser');
\TYPO3\CMS\Extbase\Utility\DebuggerUtility::var_dump($queryParser->parseQuery($query));
For TYPO3 8.7+ use this code instead:
$queryParser = \TYPO3\CMS\Core\Utility\GeneralUtilityGeneralUtility::makeInstance(\TYPO3\CMS\Extbase\Persistence\Generic\Storage\Typo3DbQueryParser::class);
$doctrineQueryBuilder = $queryParser->convertQueryToDoctrineQueryBuilder($query);
$doctrineQueryBuilderSQL = $doctrineQueryBuilder->getSQL();
$doctrineQueryBuilderParameters = $doctrineQueryBuilder->getParameters();
Check this snippet, although it's not very comfortable in use it helps a lot:
in general you need this code at the end of the buildQuery(array $sql) method (*) - right before return $statement;
if (in_array("your_table_name", $sql['tables'])) {
var_dump($statement);
print_r($statement);
}
(*) Class file:
TYPO3 ver.: 4.x: typo3/sysext/extbase/Classes/Persistence/Storage/Typo3DbBackend.php
TYPO3 ver.: 6.x: typo3/sysext/extbase/Classes/Persistence/Generic/Storage/Typo3DbBackend.php
In 6.2.x ...
You can try within \TYPO3\CMS\Core\Database\DatabaseConnection::exec_SELECTquery method, just add the condition after fetching the $query, like (trim is important!):
public function exec_SELECTquery($select_fields, $from_table, $where_clause, $groupBy = '', $orderBy = '', $limit = '') {
$query = $this->SELECTquery($select_fields, $from_table, $where_clause, $groupBy, $orderBy, $limit);
if (trim($from_table) == 'fe_users') {
DebuggerUtility::var_dump($query);
}
// rest of method
An easy way without changing any Typo3 core code and not mentioned in any forum so far is using the php "serialize()" method:
$result = $query->execute();
echo (serialize($result));
In the result object you find the SQL query ("statement;" ...)
Improvement to biesiors answer:
As Extbase replaces some placeholders after calling buildQuery(), you might prefer to place the debug output into getObjectDataByQuery(), just after $this->replacePlaceholders($sql, $parameters, $tableName);
if (strpos($sql, "your_table_name.")) {
debug($sql, 'my debug output');
};
Also, better use debug() instead of var_dump().
[File: typo3\sysext\extbase\Classes\Persistence\Generic\Storage\Typo3DbBackend.php. Line 339 in version 6.1]:
$query = $this->createQuery();
$query->getQuerySettings()->setReturnRawQueryResult(TRUE);
$getHotelInfo = 'SELECT * FROM `my_table` WHERE field = ? ORDER BY date DESC LIMIT 1';
return $query->statement($getHotelInfo)->execute();
For executing query you have to write 'setReturnQueryResult' on your repository
I just extended the above snippet, with a $_GET condition.
for debugging, just append "?dbg_table=tx_some_of_my_tables" to your address, and you're ready to go ;-)
if (in_array($_GET['dbg_table'], $sql['tables'])) {
echo('<div style="background: #ebebeb; border: 1px solid #999; margin-bottom: 20px; padding: 10px;"><pre style="white-space: normal">'.$statement.'</pre></div>');
}
A cleaner way to debug your statements when using TYPO3 6.1 is to use the query parser of Typo3DbBackend.
$parser = \TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance('TYPO3\\CMS\\Extbase\\Persistence\\Generic\\Storage\\Typo3DbBackend');
$params = array();
$queryParts = $parser->parseQuery($query, $params);
\TYPO3\CMS\Core\Utility\GeneralUtility::devLog('query', 'my_extension', 1, array('query' => $queryParts, 'params' => $params));
The parser returns an array containing the different parts of the generated SQL statement.
With TYPO3 6.2 the parseQuery method was moved to Typo3DbQueryParser and lost its second parameter.
i suggest set this in typo3conf/LocalConfiguration.php file under 'SYS' array
'SYS' => array(
......
'displayErrors' => 1,
'sqlDebug' => 1
.......
)
and then write wrong field name in query intentionally and then execute code.
this will show last query execute with error.
I have an query like:
SELECT id as OfferId FROM offers
WHERE concat(partycode, connectioncode) = ?
AND CURDATE() BETWEEN offer_start_date
AND offer_end_date AND id IN ("121211, 123341,151512,5145626 ");
Now I want to cache the results of this query using memcache and so my question is
How can I cache an query using memcache.
I am currently using CURDATE() which cannot be used if we want to implement caching and so how can I get current date functionality without using CURDATE() function ?
Something like this should work:
function getOffers($ids) {
$key = implode(',', $ids);
$cache = new Memcache();
$cache->connect('localhost');
$content = $cache->get($key);
if ($content === false) {
// content is not cached, so we have to run the query
$content = $yourDb->query('your query here');
$cache->add($key, $content);
}
$cache->close();
return $content;
}
getOffers(array('121211','123341','151512','5145626'));
You can take this a step further by sorting $ids so that the same "set" of IDs (but in a different order) will still take advantage of an available cache for that set.
This isn't date-sensitive, but you can make it date sensitive by adding the date string to $key
