    This cursor will execute statements and handle the result. It will not automatically

    MySQLCursor should be inherited whenever other functionallity is required.
    An example would to change the fetch* member functions to return dictionaries instead
    of lists of values.

        The arguments will be set during this session, meaning
        they will be called like  _<procname>__arg<nr> where
        <nr> is an enumeration (+1) of the arguments.

        Coding Example:
          1) Defining the Stored Routine in MySQL:
          CREATE PROCEDURE multiply(IN pFac1 INT, IN pFac2 INT, OUT pProd INT)
          BEGIN
            SET pProd := pFac1 * pFac2;
          END

          2) Executing in Python:
          args = (5, 5, 0)  # 0 is to hold pprod
          await cursor.callproc('multiply', args)
          print(await cursor.fetchone())

        For OUT and INOUT parameters the user should provide the
        type of the parameter as well. The argument should be a
        tuple with first item as the value of the parameter to pass
        and second argument the type of the argument.

        In the above example, one can call callproc method like:
          args = (5, 5, (0, 'INT'))
          await cursor.callproc('multiply', args)

        The type of the argument given in the tuple will be used by
        the MySQL CAST function to convert the values in the corresponding
        MySQL type (See CAST in MySQL Reference for more information)

        Does not return a value, but a result set will be
        available when the CALL-statement execute successfully.
        Raises exceptions when something is wrong.

    This class is a blend of features from MySQLCursorDict and MySQLCursorPrepared

    Multiple inheritance in python is allowed but care must be taken
    when assuming methods resolution. In the case of multiple
    inheritance, a given attribute is first searched in the current
    class if it's not found then it's searched in the parent classes.
    The parent classes are searched in a left-right fashion and each
    class is searched once.
    Based on python's attribute resolution, in this case, attributes
    are searched as follows:
    1. MySQLCursorPreparedDict (current class)
    2. MySQLCursorDict (left parent class)
    3. MySQLCursorPrepared (right parent class)
    4. MySQLCursor (base class)

        When no more rows are available, it returns an empty list.
        The number of rows returned can be specified using the size argument,
        which defaults to one.

        Returns:
            list: The next set of rows of a query result set represented
                  as a list of dictionaries where column names are used as keys.
