Syntax options:

    INTO parameter | INTO qualified-parameter | INTO variable

    Specifies output parameters or variables whose values are
    returned by a successful EXECUTE statement.

    When you specify a list of parameters or variables, the number
    of parameters in the list must be the same as the number of
    output parameter markers in the statement string of the prepared
    statement. If SQL determines that a statement string had no
    output parameter markers, the INTO clause is not allowed.
