ORACLE-SQL: stored procedure using array as parameter for select

Question

I have to use an array into my stored procedure. So I created a type variable:

CREATE OR REPLACE TYPE integer_array is table of number;

Then I tried to write my stored procedure, but I can't to compile it:

create or replace
PROCEDURE SP_TEST(
      i_id_profiles in integer_array, 
      o_clients OUT SYS_REFCURSOR
   )
AS
BEGIN
open o_clients for 
    FOR i IN 1..i_id_profiles.count LOOP
      select a.id_client from b_client a, i_client_profile b where a.id_client = b.id_client 
      and b.id_profile = i_id_profiles(i);
    END LOOP;
END SP_TEST;

Can you help me? I want to get a SYS_REFCURSOR of my select.

thanks

Answer 1

You open a ref cursor for a query(static or dynamic), you cannot open a ref cursor for a for loop construct or any kind of loop construct. It simply semantically incorrect. Moreover, in this situation, there is no need of a loop of any kind at all. As you've created the integer_array as sql type(schema object) you can use table operator to simply select from the instance of that type(represent it as a table). So your procedure might look like this:

create or replace PROCEDURE SP_TEST(
      i_id_profiles in integer_array, 
      o_clients OUT SYS_REFCURSOR
   )
AS
BEGIN
  open o_clients for 
      select a.id_client 
         from b_client a 
         join i_client_profile b 
           on (a.id_client = b.id_client)
         join table(i_id_profiles)  s
           on b.id_profile = s.column_value;
END SP_TEST;
