PL/SQL program not working when connect database via SqlNet

Question

Hi,
This is a segment of a PL/SQL program before opening a cursor using input descriptor. It is working fine ( to get the value of unOutputCount ) without connect to a database via SqlNet, can anyone tell me why it is not working ( unOutputCount return 0)while connecting to a database via SqlNet and how to make it work without opening a cursor before DESCRIBE OUTPUT ...?
EXEC SQL ALLOCATE DESCRIPTOR GLOBAL 'input_111'
WITH MAX 100;
EXEC SQL ALLOCATE DESCRIPTOR GLOBAL 'output_111'
WITH MAX 100;
EXEC SQL PREPARE STMT1 FROM :psSqlStatement;
EXEC SQL DECLARE CURSOR1 CURSOR FOR STMT1;
EXEC SQL DESCRIBE INPUT STMT1
USING DESCRIPTOR GLOBAL 'input_111';
/* Get count of input parameters in statement */
EXEC SQL GET DESCRIPTOR GLOBAL 'input_111' :unInputCount = COUNT;
EXEC SQL DESCRIBE OUTPUT STMT1
USING DESCRIPTOR GLOBAL 'output_111';
/* Get count of output parameters in statement */
EXEC SQL GET DESCRIPTOR GLOBAL 'output_111'
:unOutputCount = COUNT;

Hi,
Welcome to Oracle OTN Forums!
I changed your code a little. I think this help you
CREATE OR REPLACE
PROCEDURE xx_test
IS
  v_pid VARCHAR2(100);
  v_cn  VARCHAR2(100);
  v_id  VARCHAR2(1000);
  v_val VARCHAR2(1000);
  CURSOR C1
  IS
    (SELECT product_id, 'PRODUCT_ID'  cn
        FROM product1 );
  BEGIN
    FOR V1 IN C1
    LOOP
      FETCH C1 INTO v_pid, v_cn;
      dbms_output.put_line('==== '||v_pid||'==== '||v_cn);
      EXECUTE IMMEDIATE
      'SELECT product_id, DECODE(COUNT (product_id),1,MAX (product_id))||'''||V_CN||''' as val
        FROM product1
       WHERE product_id =:a
       GROUP BY product_id)' INTO v_id, v_val USING v_pid;
      dbms_output.put_line('==== '||v_id||'==== '||v_val);
      EXECUTE IMMEDIATE 'UPDATE product2 SET '||v_cn||' = ' ||''''|| v_val ||''''|| ' WHERE product_id = :b' USING v_pid;
      dbms_output.put_line('++++ '||v_cn||'++++ '||v_val||'++++ '||v_pid);
    END LOOP;
  END xx_test;
