datatype_ARG Procedure

This procedure provides the data that is to be passed to a deferred remote procedure call. Depending upon the type of the data that you need to pass to a procedure, you must call one of the following procedures for each argument to the procedure.

You must specify each parameter in your procedure using the datatype_ARG procedure after you execute DBMS_DEFER.CALL. That is, you cannot use the default parameters for the deferred remote procedure call. For example, suppose you have the following procedure:

CREATE OR REPLACE PACKAGE my_pack AS
   PROCEDURE my_proc(a VARCHAR2, b VARCHAR2 DEFAULT 'SALES');
END;
/

When you run the DBMS_DEFER.CALL procedure, you must include a separate procedure call for each parameter in the my_proc procedure:

CREATE OR REPLACE PROCEDURE load_def_tx IS
   node DBMS_DEFER.NODE_LIST_T;
BEGIN
   node(1) := 'MYCOMPUTER.WORLD';
   node(2) := NULL;
   DBMS_DEFER.TRANSACTION(node);
   DBMS_DEFER.CALL('PR', 'MY_PACK', 'MY_PROC', 2);
   DBMS_DEFER.VARCHAR2_ARG('TEST');
   DBMS_DEFER.VARCHAR2_ARG('SALES'); -- required, cannot omit to use default
END;
/

Note: The AnyData_ARG procedure supports the following user-defined types: object types, collections, and REFs. See Oracle9i SQL Reference and Oracle9i Application Developer's Guide - Object-Relational Features for more information about the AnyData datatype. This procedure uses abbreviations for some datetime and interval datatypes. For example, TSTZ is used for the TIMESTAMP WITH TIME ZONE datatype. For information about these abbreviations, see "Abbreviations for Datetime and Interval Datatypes".
