ActiveQuery represents a Sphinx query associated with an Active Record class.

An ActiveQuery can be a normal query or be used in a relational context.

ActiveQuery instances are usually created by yii\sphinx\ActiveRecord::find() and yii\sphinx\ActiveRecord::findBySql(). Relational queries are created by yii\sphinx\ActiveRecord::hasOne() and yii\sphinx\ActiveRecord::hasMany().

Normal Query

Because ActiveQuery extends from yii\sphinx\Query, one can use query methods, such as where(), orderBy() to customize the query options.

ActiveQuery also provides the following additional query options:

  • with(): list of relations that this query should be performed with.
  • indexBy(): the name of the column by which the query result should be indexed.
  • asArray(): whether to return each record as an array.

These options can be configured using methods of the same name. For example:

$articles = Article::find()->with('source')->asArray()->all();

ActiveQuery allows to build the snippets using sources provided by ActiveRecord. You can use snippetByModel() method to enable this. For example:

class Article extends ActiveRecord
{
    public function getSource()
    {
        return $this->hasOne('db', ArticleDb::className(), ['id' => 'id']);
    }

    public function getSnippetSource()
    {
        return $this->source->content;
    }

    ...
}

$articles = Article::find()->with('source')->snippetByModel()->all();

Relational query

In relational context ActiveQuery represents a relation between two Active Record classes.

Relational ActiveQuery instances are usually created by calling yii\sphinx\ActiveRecord::hasOne() and yii\sphinx\ActiveRecord::hasMany(). An Active Record class declares a relation by defining a getter method which calls one of the above methods and returns the created ActiveQuery object.

A relation is specified by $link which represents the association between columns of different tables; and the multiplicity of the relation is indicated by $multiple.

If a relation involves a junction table, it may be specified by via(). This methods may only be called in a relational context. Same is true for inverseOf(), which marks a relation as inverse of another relation.

public $this addGroupBy ( $columns )
$columns string|array|yii\db\ExpressionInterface

Additional columns to be grouped by. Columns can be specified in either a string (e.g. "id, name") or an array (e.g. ['id', 'name']). The method will automatically quote the column names unless a column contains some parenthesis (which means the column contains a DB expression).

Note that if your group-by is an expression containing commas, you should always use an array to represent the group-by information. Otherwise, the method will not be able to correctly determine the group-by columns.

Since version 2.0.7, an yii\db\Expression object can be passed to specify the GROUP BY part explicitly in plain SQL. Since version 2.0.14, an yii\db\ExpressionInterface object can be passed as well.

Columns can be specified in either a string (e.g. "id ASC, name DESC") or an array (e.g. ['id' => Query::SORT_ASC, 'name' => Query::SORT_DESC]). The method will automatically quote the column names unless a column contains some parenthesis (which means the column contains a DB expression).

return $this

The query object itself

                public function addWithin($columns)
{
    $columns = $this->normalizeOrderBy($columns);
    if ($this->within === null) {
        $this->within = $columns;

andFilterCompare() public method (available since version 2.0.8)

Defined in: yii\db\Query::andFilterCompare()

Adds a filtering condition for a specific column and allow the user to choose a filter operator.

It adds an additional WHERE condition for the given field and determines the comparison operator based on the first few characters of the given value. The condition is added in the same way as in andFilterWhere() so empty values are ignored. The new condition and the existing one will be joined using the AND operator.

The comparison operator is intelligently determined based on the first few characters in the given value. In particular, it recognizes the following operators if they appear as the leading characters in the given value:

  • <: the column must be less than the given value.
  • >: the column must be greater than the given value.
  • <=: the column must be less than or equal to the given value.
  • >=: the column must be greater than or equal to the given value.
  • <>: the column must not be the same as the given value.
  • =: the column must be equal to the given value.
  • If none of the above operators is detected, the $defaultOperator will be used.
public $this andFilterCompare ( $name, $value, $defaultOperator '=' )
$name string

The column name.

$value string

The column value optionally prepended with the comparison operator.

$defaultOperator string

        $operator = $matches[1];
        $value = substr($value, strlen($operator));
    } else {
        $operator = $defaultOperator;
    }
    return $this->andFilterWhere([$operator, $name, $value]);
}

            
andFilterHaving() public method (available since version 2.0.11)

Defined in: yii\db\Query::andFilterHaving()

A batch query supports fetching data in batches, which can keep the memory usage under a limit. This method will return a yii\db\BatchQueryResult object which implements the Iterator interface and can be traversed to retrieve the data in batches.

For example,

$query = (new Query)->from('user');
foreach ($query->batch() as $rows) {
    // $rows is an array of 100 or fewer rows from user table
}
public yii\db\BatchQueryResult batch ( $batchSize 100, $db null )

Defined in: yii\base\Component::behaviors()

Returns a list of behaviors that this component should behave as.

Child classes may override this method to specify the behaviors they want to behave as.

The return value of this method should be an array of behavior objects or configurations indexed by behavior names. A behavior configuration can be either a string specifying the behavior class or an array of the following structure:

'behaviorName' => [
    'class' => 'BehaviorClass',
    'property1' => 'value1',
    'property2' => 'value2',
]

Note that a behavior class must extend from yii\base\Behavior. Behaviors can be attached using a name or anonymously. When a name is used as the array key, using this name, the behavior can later be retrieved using getBehavior() or be detached using detachBehavior(). Anonymous behaviors can not be retrieved or detached.

Behaviors declared in this method will be attached to the component automatically (on demand).

filterHaving() public method (available since version 2.0.11)

Defined in: yii\db\Query::filterHaving()

Sets the HAVING part of the query but ignores empty operands.

This method is similar to having(). The main difference is that this method will remove empty query operands. As a result, this method is best suited for building query conditions based on filter values entered by users.

The following code shows the difference between this method and having():

// HAVING `age`=:age
$query->filterHaving(['name' => null, 'age' => 20]);
// HAVING `age`=:age
$query->having(['age' => 20]);
// HAVING `name` IS NULL AND `age`=:age
$query->having(['name' => null, 'age' => 20]);

Note that unlike having(), you cannot pass binding parameters to this method.

See also:

public $this filterHaving ( array $condition )
$condition array

The conditions that should be put in the HAVING part. See having() on how to specify this parameter.

return $this

}

            
filterWhere() public method

Defined in: yii\db\QueryTrait::filterWhere()

Sets the WHERE part of the query but ignores empty operands.

This method is similar to where(). The main difference is that this method will remove empty query operands. As a result, this method is best suited for building query conditions based on filter values entered by users.

The following code shows the difference between this method and where():

// WHERE `age`=:age
$query->filterWhere(['name' => null, 'age' => 20]);
// WHERE `age`=:age
$query->where(['age' => 20]);
// WHERE `name` IS NULL AND `age`=:age
$query->where(['name' => null, 'age' => 20]);

Note that unlike where(), you cannot pass binding parameters to this method.

See also:

public $this filterWhere ( array $condition )

        }
        $relation->populateRelation($name, $models);
    }
}

            
from() public method

Defined in: yii\db\Query::from()

Sets the FROM part of the query.

public $this from ( $tables )
$tables string|array|yii\db\ExpressionInterface

The table(s) to be selected from. This can be either a string (e.g. 'user') or an array (e.g. ['user', 'profile']) specifying one or several table names. Table names can contain schema prefixes (e.g. 'public.user') and/or table aliases (e.g. 'user u'). The method will automatically quote the table names unless it contains some parenthesis (which means the table is given as a sub-query or DB expression).

When the tables are specified as an array, you may also use the array keys as the table aliases (if a table does not need alias, do not use a string key).

Use a Query object to represent a sub-query. In this case, the corresponding array key will be used as the alias for the sub-query.

To specify the FROM part in plain SQL, you may pass an instance of yii\db\ExpressionInterface.

Here are some examples:

// SELECT * FROM  `user` `u`, `profile`;
$query = (new \yii\db\Query)->from(['u' => 'user', 'profile']);

// SELECT * FROM (SELECT * FROM `user` WHERE `active` = 1) `activeusers`;
$subquery = (new \yii\db\Query)->from('user')->where(['active' => true])
$query = (new \yii\db\Query)->from(['activeusers' => $subquery]);

// subquery can also be a string with plain SQL wrapped in parenthesis
// SELECT * FROM (SELECT * FROM `user` WHERE `active` = 1) `activeusers`;
$subquery = "(SELECT * FROM `user` WHERE `active` = 1)";
$query = (new \yii\db\Query)->from(['activeusers' => $subquery]);
return $this

The query object itself

                public function from($tables)
{
    if ($tables instanceof ExpressionInterface) {
        $tables = [$tables];
    }

$columns string|array|yii\db\ExpressionInterface|null

The columns to be grouped by. Columns can be specified in either a string (e.g. "id, name") or an array (e.g. ['id', 'name']). The method will automatically quote the column names unless a column contains some parenthesis (which means the column contains a DB expression).

Note that if your group-by is an expression containing commas, you should always use an array to represent the group-by information. Otherwise, the method will not be able to correctly determine the group-by columns.

Since version 2.0.7, an yii\db\ExpressionInterface object can be passed to specify the GROUP BY part explicitly in plain SQL. Since version 2.0.14, an yii\db\ExpressionInterface object can be passed as well.

function ($row)
{
    // return the index value corresponding to $row
}
return $this

The query object itself

                public function indexBy($column)

public void init ( )

                public function init()
{
    parent::init();
    $this->trigger(self::EVENT_INIT);
}

            
innerJoin() public method

Defined in: yii\sphinx\Query::innerJoin()

Appends an INNER JOIN part to the query.

public $this innerJoin ( $table, $on '', $params = [] )
$table string|array

The table or sub-query to be joined.

Use a string to represent the name of the table to be joined. The table name can contain a schema prefix (e.g. 'public.user') and/or table alias (e.g. 'user u'). The method will automatically quote the table name unless it contains some parenthesis (which means the table is given as a sub-query or DB expression).

You may also specify the table as an array with one element, using the array key as the table alias (e.g. ['u' => 'user']).

To join a sub-query, use an array with one element, with the value set to a yii\sphinx\Query object representing the sub-query, and the corresponding key representing the alias.

$on string|array

The join condition that should appear in the ON part. Please refer to join() on how to specify this parameter.

$params array

The parameters (name => value) to be bound to the query.

return $this

The query object itself

                public function innerJoin($table, $on = '', $params = [])
{
    throw new NotSupportedException('"' . __METHOD__ . '" is not supported.');
}

            
inverseOf() public method

Defined in: yii\db\ActiveRelationTrait::inverseOf()

Sets the name of the relation that is the inverse of this relation.

For example, a customer has orders, which means the inverse of the "orders" relation is the "customer". If this property is set, the primary record(s) will be referenced through the specified relation. For example, $customer->orders[0]->customer and $customer will be the same object, and accessing the customer of an order will not trigger a new DB query.

Use this method when declaring a relation in the yii\db\ActiveRecord class, e.g. in Customer model:

public function getOrders()
{
    return $this->hasMany(Order::class, ['customer_id' => 'id'])->inverseOf('customer');
}

This also may be used for Order model, but with caution:

public function getCustomer()
{
    return $this->hasOne(Customer::class, ['id' => 'customer_id'])->inverseOf('orders');
}

in this case result will depend on how order(s) was loaded. Let's suppose customer has several orders. If only one order was loaded:

$orders = Order::find()->where(['id' => 1])->all();
$customerOrders = $orders[0]->customer->orders;

variable $customerOrders will contain only one order. If orders was loaded like this:

$orders = Order::find()->with('customer')->where(['customer_id' => 1])->all();
$customerOrders = $orders[0]->customer->orders;

variable $customerOrders will contain all orders of the customer.

public $this inverseOf ( $relationName )
$relationName string

The name of the relation that is the inverse of this relation.

return $this

The relation object itself.

                public function inverseOf($relationName)
{
    $this->inverseOf = $relationName;
    return $this;
}

            
isEmpty() protected method

Defined in: yii\db\QueryTrait::isEmpty()

Returns a value indicating whether the give value is "empty".

The value is considered "empty", if one of the following conditions is satisfied:

  • it is null,
  • an empty string (''),
  • a string containing only whitespace characters,
  • or an empty array.
protected boolean isEmpty ( $value )
$value mixed
return boolean

If the value is empty

                protected function isEmpty($value)
{
    return $value === '' || $value === [] || $value === null || is_string($value) && trim($value) === '';
}

            
join() public method

Defined in: yii\sphinx\Query::join()

Appends a JOIN part to the query.

The first parameter specifies what type of join it is.

public $this join ( $type, $table, $on '', $params = [] )
$type string

The type of join, such as INNER JOIN, LEFT JOIN.

$table string|array

The table or sub-query to be joined.

Use a string to represent the name of the table to be joined. The table name can contain a schema prefix (e.g. 'public.user') and/or table alias (e.g. 'user u'). The method will automatically quote the table name unless it contains some parenthesis (which means the table is given as a sub-query or DB expression).

You may also specify the table as an array with one element, using the array key as the table alias (e.g. ['u' => 'user']).

To join a sub-query, use an array with one element, with the value set to a yii\sphinx\Query object representing the sub-query, and the corresponding key representing the alias.

$on string|array

The join condition that should appear in the ON part. Please refer to where() on how to specify this parameter.

Note that the array format of where() is designed to match columns to values instead of columns to columns, so the following would not work as expected: ['post.author_id' => 'user.id'], it would match the post.author_id column value against the string 'user.id'. It is recommended to use the string syntax here which is more suited for a join:

'post.author_id = user.id'
$params array

The parameters (name => value) to be bound to the query.

return $this

The query object itself

                public function join($type, $table, $on = '', $params = [])
{
    throw new NotSupportedException('"' . __METHOD__ . '" is not supported.');
}

The table or sub-query to be joined.

Use a string to represent the name of the table to be joined. The table name can contain a schema prefix (e.g. 'public.user') and/or table alias (e.g. 'user u'). The method will automatically quote the table name unless it contains some parenthesis (which means the table is given as a sub-query or DB expression).

You may also specify the table as an array with one element, using the array key as the table alias (e.g. ['u' => 'user']).

To join a sub-query, use an array with one element, with the value set to a yii\sphinx\Query object representing the sub-query, and the corresponding key representing the alias.

$on string|array

The join condition that should appear in the ON part. Please refer to join() on how to specify this parameter.

                public function limit($limit)
{
    $this->limit = $limit;
    return $this;
}

            
match() public method

Defined in: yii\sphinx\Query::match()

Sets the fulltext query text. This text will be composed into MATCH operator inside the WHERE clause.

Note: this value will be processed by yii\sphinx\Connection::escapeMatchValue(), if you need to compose complex match condition use yii\db\Expression:

$query = new Query();
$query->from('my_index')
    ->match(new Expression(':match', ['match' => '@(content) ' . Yii::$app->sphinx->escapeMatchValue($matchValue)]))
    ->all();

orderBy() public method

Defined in: yii\db\QueryTrait::orderBy()

Sets the ORDER BY part of the query.

See also addOrderBy().

public $this orderBy ( $columns )
$columns string|array|yii\db\ExpressionInterface|null

The columns (and the directions) to be ordered by. Columns can be specified in either a string (e.g. "id ASC, name DESC") or an array (e.g. ['id' => SORT_ASC, 'name' => SORT_DESC]).

The method will automatically quote the column names unless a column contains some parenthesis (which means the column contains a DB expression).

Note that if your order-by is an expression containing commas, you should always use an array to represent the order-by information. Otherwise, the method will not be able to correctly determine the order-by columns.

Since version 2.0.7, an yii\db\ExpressionInterface object can be passed to specify the ORDER BY part explicitly in plain SQL.

select() public method

Defined in: yii\db\Query::select()

Sets the SELECT part of the query.

public $this select ( $columns, $option null )
$columns string|array|yii\db\ExpressionInterface

The columns to be selected. Columns can be specified in either a string (e.g. "id, name") or an array (e.g. ['id', 'name']). Columns can be prefixed with table names (e.g. "user.id") and/or contain column aliases (e.g. "user.id AS user_id"). The method will automatically quote the column names unless a column contains some parenthesis (which means the column contains a DB expression). A DB expression may also be passed in form of an yii\db\ExpressionInterface object.

Note that if you are selecting an expression like CONCAT(first_name, ' ', last_name), you should use an array to specify the columns. Otherwise, the expression may be incorrectly split into several parts.

When the columns are specified as an array, you may also use array keys as the column aliases (if a column does not need alias, do not use a string key).

Starting from version 2.0.1, you may also select sub-queries as columns by specifying each such column as a Query instance representing the sub-query.

$option string|null

       return $this->hasMany(OrderItem::class, ['order_id' => 'id']);
   }

   public function getItems() {
       return $this->hasMany(Item::class, ['id' => 'item_id'])
                   ->via('orderItems');
   }
}
public $this via ( $relationName, callable $callable null )
$relationName string

The relation name. This refers to a relation declared in $primaryModel.

$callable callable|null

A PHP callback for customizing the relation associated with the junction table. Its signature should be function($query), where $query is the query to be customized.

return $this

The relation object itself.

                public function via($relationName, callable $callable = null)
{
    $relation = $this->primaryModel->getRelation($relationName);
    $callableUsed = $callable !== null;
    $this->via = [$relationName, $relation, $callableUsed];
    if ($callable !== null) {
        call_user_func($callable, $relation);
    }
    return $this;
}

            
where() public method

Defined in: yii\db\QueryTrait::where()

Sets the WHERE part of the query.

See yii\db\QueryInterface::where() for detailed documentation.

See also:

public $this where ( $condition )
$condition string|array|yii\db\ExpressionInterface

The conditions that should be put in the WHERE part.

return $this

The query object itself

                public function where($condition)
{
    $this->where = $condition;
    return $this;
}

            
with() public method

Defined in: yii\db\ActiveQueryTrait::with()

Specifies the relations with which this query should be performed.

The parameters to this method can be either one or multiple strings, or a single array of relation names and the optional callbacks to customize the relations.

A relation name can refer to a relation defined in $modelClass or a sub-relation that stands for a relation of a related record. For example, orders.address means the address relation defined in the model class corresponding to the orders relation.

The following are some usage examples:

// find customers together with their orders and country
Customer::find()->with('orders', 'country')->all();
// find customers together with their orders and the orders' shipping address
Customer::find()->with('orders.address')->all();
// find customers together with their country and orders of status 1
Customer::find()->with([
    'orders' => function (\yii\db\ActiveQuery $query) {
        $query->andWhere('status = 1');
    },
    'country',
])->all();

You can call with() multiple times. Each call will add relations to the existing ones. For example, the following two statements are equivalent:

Customer::find()->with('orders', 'country')->all();
Customer::find()->with('orders')->with('country')->all();
public $this with ( )
return $this

The query object itself

                public function with()
{
    $with = func_get_args();
    if (isset($with[0]) && is_array($with[0])) {
        // the parameter is given as an array
        $with = $with[0];
    }
    if (empty($this->with)) {
        $this->with = $with;
    } elseif (!empty($with)) {
        foreach ($with as $name => $value) {
            if (is_int($name)) {
                // repeating relation is fine as normalizeRelations() handle it well
                $this->with[] = $value;
            } else {
                $this->with[$name] = $value;
            }
        }
    }
    return $this;
}

            
withQuery() public method (available since version 2.0.35)

Defined in: yii\db\Query::withQuery()

Prepends a SQL statement using WITH syntax.

public $this withQuery ( $query, $alias, $recursive false )
$query string|yii\db\Query

The SQL statement to be prepended using WITH

$alias string

Query alias in WITH construction

$recursive boolean

TRUE if using WITH RECURSIVE and FALSE if using WITH

return $this

The query object itself

                public function withQuery($query, $alias, $recursive = false)
{
    $this->withQueries[] = ['query' => $query, 'alias' => $alias, 'recursive' => $recursive];
    return $this;
}

            
within() public method

Defined in: yii\sphinx\Query::within()

Sets the WITHIN GROUP ORDER BY part of the query.

See also addWithin().

public $this within ( $columns )
$columns string|array

The columns (and the directions) to find best row within a group. Columns can be specified in either a string (e.g. "id ASC, name DESC") or an array (e.g. ['id' => Query::SORT_ASC, 'name' => Query::SORT_DESC]). The method will automatically quote the column names unless a column contains some parenthesis (which means the column contains a DB expression).

return $this

The query object itself

                public function within($columns)
{
    $this->within = $this->normalizeOrderBy($columns);
    return $this;
}
