Using the IN command with parameters

Question

I am using .Net with the Oracle 10G client software to connect to a 10G database. I have a package that contains a stored procedure where I need to pass in multiple values to utilize the IN command, but I keep getting a cryptic Oracle error. Basically this is the scenario..
SELECT * FROM [Table] WHERE ID IN(P_PARAMETER);
Through my .Net code, I set P_PARAMETER equal to something like "25,31,36,48" without the double quotes. I also tried surrounding each number with single quotes and it still bombed out. Is this valid to do? If not, what are my options since I need to use this scenario (the numbers aren't known ahead of time)?

Answer 1

may be you are looking for this, you have to use dynamic sql,
i am using ref cursor to display the data, basically the inlist you are passing is comma seprated as under
SQL> var c refcursor;
SQL> var NO VARCHAR2(200);
SQL>
---- this is the in list with comma seprated
SQL> EXECUTE :NO:='10,20';
PL/SQL procedure successfully completed.
-- i am paasing that in list here to procedure
SQL> CREATE OR REPLACE PROCEDURE test_in (pdno IN VARCHAR2, p_cursor OUT sys_refcursor)
  2  IS
  3       st                            VARCHAR2 (200);
  4       vename                        VARCHAR2 (20);
  5  BEGIN
  6       st         := 'SELECT empno,ename  FROM emp  WHERE dno in ('||pdno||')';
  7       DBMS_OUTPUT.PUT_LINE (pdno);
  8       DBMS_OUTPUT.PUT_LINE (st);
  9       OPEN p_cursor FOR st ;
10  END test_in;
11  /
Procedure created.
-- calling the procedure
SQL> EXECUTE  test_in (:NO,:c);
10,20
--- this how the statement will look like
SELECT empno,ename  FROM emp  WHERE dno in (10,20)
PL/SQL procedure successfully completed.
printing the out put
SQL> print :c;
     EMPNO ENAME
      7369 SMITH
      7566 JONES
      7782 CLARK
      7788 SCOTT
      7839 KING
      7876 ADAMS
      7902 FORD
      7934 MILLER
