 * @example

 * Note: We must use prefix (from connection) with tables with scema equal defaultSchema or without schema and don't use with other schemas
 * Note: With ExpressionInterface as tablename - we cannot add prefixes and quoting of table names.
 * For example with Oracle: (new Query)->select('*')->from(new Expression('dblink1.dbo.table')) for build `select * from dblink1.dbo.table1`

It seems like $alias can also be of type Yiisoft\Db\Expression\ExpressionInterface. However, the property $alias is declared as type null|string. Maybe add an additional type check?

        $this->schema = $schema;
    }

    {
        assert(is_string($name) || $name instanceof ExpressionInterface);
        assert(is_string($schema) || $schema instanceof ExpressionInterface || $schema === null);

        return new self($name, $alias, $schema);
    }
