I am trying to fetch the single row using the pdo statement, but i am getting the error like ..
Fatal error: call to undefined method fetch()
$sql = new Sql( $this->adapter );
$select = $sql->select();
$select->from('users');
$where = new Where();
$where->equalTo('user_id',$userId);
$select->where($where);
//echo $select->getSqlString($this->adapter->getPlatform());
$statement = $sql->prepareStatementForSqlObject($select);
$result = $statement->execute();
$row = $statement->fetch();
//getting the result set for the below, but not the above statement fetch
$rows = array_values(iterator_to_array($result));
There's no "fetch" method in the statement object. If you want to get a single row then get the current entry of the result iterator, like so:
$row = $result->current();

The below PHQL generates a complex resultset like it should:
$phql = "SELECT User.*, ProductUser.* "
. "FROM ProductUser "
. "INNER JOIN User "
. "WHERE ProductUser.product_id = 5";
Replacing ProductUser.* with an existing column like ProductUser.id causes an error:
MESSAGE: The index does not exist in the row
FILE: phalcon/mvc/model/row.zep
LINE: 67
This is version 2.0.6. Is this a bug or am I making a mistake somewhere? According to the documentation it should be fine.
It was my mistake (expecting the row to always be an object).
I hope this helps someone because looping complex resultsets is not in the documentation.
$result = $this->modelsManager->createQuery($phql)->execute();
if ($result instanceof \Phalcon\Mvc\Model\Resultset\Complex) {
foreach ($result as $rows) {
foreach ($rows as $row) {
if (is_object($row)) {
$modelData = $row->toArray());
// this is what I needed
} else {
$id = $row;
}
}
}
}
First of all you're missing the ON clause in your query.
Anyways, it's easier and more error prone to use Phalcon's query builder for querying:
<?php
// modelManager is avaiable in the default DI
$queryBuilder = $this->modelsManager->createBuilder();
$queryBuilder->from(["product" => 'Path\To\ProductUser']);
// Inner join params are: the model class path, the condition for the 'ON' clause, and optionally an alias for the table
$queryBuilder->innerJoin('Path\To\User', "product.user_id = user.id", "user");
$queryBuilder->columns([
"product.*",
"user.*"
]);
$queryBuilder->where("product.id = 5");
// You can use this line to debug what was generated
// $generatedQuery = $queryBuilder->getPhql();
// var_dump($generatedQuery);
// Finish the query building
$query = $queryBuilder->getQuery();
// Execute it and get the results
$result = $query->execute();
// Now use var_dump to see how the result was fetched
var_dump($result);
exit;
I have a data object related to some other data objects and I am trying to build a reporting page for them.
So far I've got the code below in my page controller to display a form where I will begin to select filtering options for the report.
However I am getting this error due to the left join:
[Warning] Missing argument 2 for SQLQuery::addLeftJoin()
It would seem that the raw2sql is outputting this when I've debugged:
\'AgeRangeData\', \'CallEvent.AgeRangeData ID=AgeRangeData.ID)\'
I'm assuming that the backslashes is what is causing the error
public function ReportingFilter(){
$DataObjectsList = $this->dbObject('DataObjects')->enumValues();
$fields = new FieldList(
new DropdownField('DataObjects', 'Data Objects', $DataObjectsList)
);
$actions = new FieldList(
new FormAction("FilterObjects", "Filter")
);
return new Form($this, "ReportingFilter", $fields, $actions);
}
public function FilterObjects($data, $form){
$data = $_REQUEST;
$query = new SQLQuery();
$object = $data['DataObjects'];
$leftJoin = Convert::raw2sql("'" . $object . "', 'CallEvent." . $object . " ID={$object}.ID)'");
$query->selectField("CallEvent.ID", "ID");
$query->setFrom('`CallEvent`');
$query->setOrderBy('CallEvent.Created DESC');
$query->addLeftJoin($leftJoin);
return $query;
}
SQLQuery::addLeftJoin() takes two arguments. The first is the table to join on and the second is the "on" clause.
You want:
$query = new SQLQuery();
$query->addLeftJoin($object, '"CallEvent"."ID" = "' . $object . '"ID"');
You'd need to escape $object appropriately, of course.
NB: Your code looks a little fragile as you're not ensuring that you $object actually has a DB table. I recommend you use ClassInfo::baseDataClass($object). This will have the added benefit that it will also sanitise your class name and ensure it's a real class.
I'm trying to perform a search in one of my tables based on a given criteria like so:
$id = 1;
$criteria = new CDbCriteria();
$criteria->addCondition("usr_currency=:currency");
$currencies = User::model()->findAll($criteria, array(':currency' => $id,));
I get a CDbException:
CDbCommand failed to execute the SQL statement:
SQLSTATE[HY093]: Invalid parameter number: no parameters were bound.
The SQL statement executed was:
SELECT * FROM `user` `t`
WHERE usr_currency=:currency
Where as, this works:
$id = 1;
$criteria = new CDbCriteria();
$criteria->addCondition("usr_currency=:currency");
$criteria->params = array(':currency' => $id,);
$comments = User::model()->findAll($criteria);
What is wrong with the first code fragment?
From CActiveRecord::find()
This is only used when the first parameter is a string (query condition). In other cases, please use CDbCriteria::params to set parameters.
I have a select statement see below. Using PDO how would I recreate this same Select statement, as I want to grab two values from it and combine them into the $geomstring. I can figure out the combine, but not the first 3 lines.
$sql1 = "SELECT easting_value, northing_value FROM gridreference_tbl WHERE gridref_id='$_POST[gridref_id]'";
$result1 = pg_query($sql1);
$row1 = pg_fetch_array($result1);
$geomstring = $row1['easting_value']. $_POST['grid_eastings']." ".$row1['northing_value'].$_POST['grid_northings'];
*php website for prepared statements says *
$stmt = $dbh->prepare("SELECT * FROM REGISTRY where name = ?");
if ($stmt->execute(array($_GET['name']))) {
while ($row = $stmt->fetch()) {
print_r($row);
}
}
I have something similar working for populating a dropdown that partly uses this
$stmt = $conn->prepare("SELECT easting_value, northing_value FROM gridreference_tbl WHERE gridref_id=$gridref_id");
$stmt->setFetchMode(PDO::FETCH_OBJ);
Found it on php.net, I was googling the wrong stuff:
$stmt4 = $conn->prepare("SELECT easting_value, northing_value from gridreference_tbl WHERE gridref_id = 4");
$stmt4->execute();
print("PDO::FETCH_ASSOC: ");
print("Return next row as an array indexed by column name\n");
$result = $stmt4->fetch(PDO::FETCH_ASSOC);
print_r($result);
print("\n");
I am new to pdo and do not get why the following insert query does not work. If I remove the line that executes the query, there will be of course no insertion, but there will be no error. If I leave that line, the script is not executed. Of course I checked and rechecked the table name and field name. Hope someone can hep me understand. Note that before executing the query, the ber_mBacth_date field of my table is set to NULL. Cheers. Marc
<?php
$db_host = 'localhost';
$db_user = 'user';
$db_password = 'user';
$db_database = 'myconsole';
$mBatchDate = date('Y-m-d H:i:s');
$connexion = new PDO("mysql:host=$db_host;dbname=$db_database", $db_user, $db_password);
$qry = $connexion->execute('UPDATE batcherrors SET ber_mBatch_date = "'.$mBatchDate.'"');
$connexion = NULL;
?>
Can you try instead of:
$connexion = new PDO("mysql:host=$db_host;dbname=$db_database", $db_user, $db_password);
$qry = $connexion->execute('UPDATE batcherrors SET ber_mBatch_date = "'.$mBatchDate.'"');
do:
$statement = $connexion->prepare("UPDATE batcherrors SET ber_mBatch_date = :mBatchDate");
$statement->bindValue(':mBatchDate', $mBatchDate, PDO::PARAM_STR);
$statement->execute();
Binding is recommended way to set parameters values (over concatenation).
