/**
17
 * Query represents a SELECT SQL statement in a way that is independent of DBMS.
18
 *
19
 * Query provides a set of methods to facilitate the specification of different clauses
20
 * in a SELECT statement. These methods can be chained together.
21
 *
22
 * By calling [[createCommand()]], we can get a [[Command]] instance which can be further
23
 * used to perform/execute the DB query against a database.
24
 *
25
 * For example,
26
 *
27
 * ```php
28
 * $query = new Query;
29
 * // compose the query
30
 * $query->select('id, name')
31
 *     ->from('user')
32
 *     ->limit(10);
33
 * // build and execute the query
34
 * $rows = $query->all();
35
 * // alternatively, you can create DB command and execute it
36
 * $command = $query->createCommand();
37
 * // $command->sql returns the actual SQL
38
 * $rows = $command->queryAll();
39
 * ```
40
 *
41
 * Query internally uses the [[QueryBuilder]] class to generate the SQL statement.
42
 *
43
 * A more detailed usage guide on how to work with Query can be found in the [guide article on Query Builder](guide:db-query-builder).

Bug Best Practice introduced by
The expression return $this->queryScalar('COUNT('.$q.')', $db) returns the type string which is incompatible with the return type mandated by yii\db\QueryInterface::count() of integer.

In the issue above, the returned value is violating the contract defined by the mentioned interface.

Let's take a look at an example:

interface HasName {
    /** @return string */
    public function getName();
}

class Name {
    public $name;
}

class User implements HasName {
    /** @return string|Name */
    public function getName() {
        return new Name('foo'); // This is a violation of the ``HasName`` interface
                                // which only allows a string value to be returned.

It seems like $tables can also be of type false or string. However, the property $from is declared as type array. Maybe add an additional type check?

Our type inference engine has found a suspicous assignment of a value to a property. This check raises an issue when a value that can be of a mixed type is assigned to a property that is type hinted more strictly.

For example, imagine you have a variable $accountId that can either hold an Id object or false (if there is no account id yet). Your code now assigns that value to the id property of an instance of the Account class. This class holds a proper account, so the id value must no longer be false.

Either this assignment is in error or a type check should be added for that assignment.

Documentation Bug introduced by
It seems like $columns can also be of type false. However, the property $groupBy is declared as type array. Maybe add an additional type check?

Our type inference engine has found a suspicous assignment of a value to a property. This check raises an issue when a value that can be of a mixed type is assigned to a property that is type hinted more strictly.

For example, imagine you have a variable $accountId that can either hold an Id object or false (if there is no account id yet). Your code now assigns that value to the id property of an instance of the Account class. This class holds a proper account, so the id value must no longer be false.

Either this assignment is in error or a type check should be added for that assignment.

class Id
{
    public $id;

    public function __construct($id)
    {
        $this->id = $id;
    }

}

class Account
{
    /** @var  Id $id */
    public $id;
}

$account_id = false;

if (starsAreRight()) {
    $account_id = new Id(42);
}

$account = new Account();
if ($account instanceof Id)
{
    $account->id = $account_id;
