Passes a list of literal, parameter values (parameter markers for
    dynamic execution), or variables to the called stored procedure.

    You can pass a literal only to an IN parameter of a stored
    procedure. You cannot pass a literal to an OUT or INOUT
    parameter.

    In SQL statements to be dynamically executed, you refer to both
    the main and indicator parameters with a single parameter marker
    (?).  See the Parameters HELP topic for details about how to
    use parameters in programs for static as well as dynamic SQL
    statement execution.
