Reference documentation and code samples for the Cloud Datastore Client class Filter.
Represents an interface to create composite and property filters for Google\Cloud\Datastore\Query\Query via static methods.
Each method returns an array representation of respective filter which is consumed by other filters or Query object.
Example:
$filter = Filter::where('CompanyName', '=', 'Google');
$query = $datastore->query();
$query->kind('Companies');
$query->filter($filter);
$results = $datastore->runQuery($query);
$finalResult = [];
foreach ($results as $result) {
$finalResult[] = $result['companyName'];
}
Composite filters can be created by using other composite/property filters.
// Or filter
$filterType = 'or';
$filterOr = Filter::or([$filter, ...$filters]);
$query = $datastore->query();
$query->kind('Companies');
$query->filter($filter);
$results = $datastore->runQuery($query);
$finalResult = [];
foreach ($results as $result) {
$finalResult[] = $result['companyName'];
}
Similaryly, AND
filter can be created using Filter::and
method.
