Ref cursor with Execute immediate

Question

I want to get the results in ref_cursor, but I am not able to do that.

Please suggest me how to get the results in ref_cursor using Execute immediate

CREATE OR REPLACE PROCEDURE TEST_PROC_QT ( p_name IN VARCHAR2,
                                           p_result_set OUT sys_refcursor ) IS

  v_sql VARCHAR2(4000);

BEGIN

   v_sql := '';
   v_sql := 'SELECT * FROM USERS WHERE 1=1 ';

   IF p_name is not null THEN
     v_sql := v_sql || ' AND login_id = :v_name';
   ELSE
     v_sql := v_sql || ' AND ((1=1) or :v_name is null)';
   END IF;

   Dbms_output.put_line(v_sql);

   EXECUTE IMMEDIATE v_sql

   --OPEN p_result_set for v_sql
   --INTO p_result_set using p_name;  

END;

Completely unrelated but a better way of writing the query (with no execute immediate) is: 'SELECT * FROM USERS WHERE login_ID = nvl(:v_name, login_id)' — Thomas Jones-Low, Jun 23 '11 at 22:44
@Thomas Jones-Low: that ain't gonna work if you have an index on that column. — Robotronx, Feb 10 '17 at 15:07

Just:

OPEN p_result_set for v_sql using p_name;

You need to create a type to keep the data you select is going to return,for example. Imagine this is yours users table user(id number, name varchar2), your type should look like:
```
create type users_type as object (id number, name varchar2);
```

Create a type table to keep object to created above.

create type users_table_object as table of users_type;

create the procedure:

create the procedure test(
cv_1  OUT SYS_REFCURSOR
....
)
as
users_table_object;
v_query VARCHAR2(2000);  

begin
v_query := N'select users_type(id, name) from users ';

execute immediate
bulk collect into users_table_object;

open cv_1 for table(users_table_object)
