Native Dynamic SQL, PL/SQL

Question

Hi all,
When I try the follwing block to perform a PL/SQL block, it gives the error ORA-06536: IN bind variable bound to an OUT position.
DECLARE
V_SQL VARCHAR2(4000);
V_E_NAME VARCHAR2(100);
BEGIN
V_SQL := 'BEGIN
SELECT EMP_NAME
INTO :1
FROM EMP
WHERE EMP_CODE = :2;
END;';
EXECUTE IMMEDIATE V_SQL USING V_E_NAME, 101;
DBMS_OUTPUT.PUT_LINE('EMP NAME - '||V_E_NAME);
EXCEPTION
WHEN OTHERS THEN
DBMS_OUTPUT.PUT_LINE('ERR - '||SQLERRM);
END;
Please help me to overcome this.
Thanks in advance.

Yes, you can declaring V_E_NAME to be an OUT bind parameter...
SQL> DECLARE
  2  V_SQL VARCHAR2(4000);
  3  V_E_NAME VARCHAR2(100);
  4  v_empno number := 7839;
  5  BEGIN
  6  V_SQL := 'BEGIN SELECT ENAME INTO :1 FROM EMP WHERE EMPNO = :2; END;';
  7  EXECUTE IMMEDIATE V_SQL USING OUT V_E_NAME,v_empno;
  8  DBMS_OUTPUT.PUT_LINE('EMP NAME - '||V_E_NAME);
  9  EXCEPTION
10  WHEN OTHERS THEN
11  DBMS_OUTPUT.PUT_LINE('ERR - '||SQLERRM);
12  END;
13  /
EMP NAME - KING
