Temporary tables in stored procedure for Oracle

Question

I have a stored procedure that runs fine on MS SQL and DB2. But cannot get it to run on Oracle as it uses temporary tables created within the procedure. I would like to know any suggestions on my stored procedure if possible. Please do not suggest execute immediate as i do not have the permission for that. This is a huge procedure so please guide me how i can do this without a temporary table. Please note that creating a temporary table before creating the procedure is also not an option.

Thanks in advance!

Do you have permissions to create database level types such as a nested table type? — Ollie

You can try, as Ollie says, with Collections. I take only your LEADS_DELETED table.

CREATE OR REPLACE TYPE Collection_LEADS_DELETED;
CREATE OR REPLACE TYPE TypeObject_LEADS_DELETED 
AS OBJECT (ID NUMBER(19));

FUNCTION your_function
   RETURN Collection_LEADS_DELETED PIPELINED
IS
     type t_array is table of number
          index by binary_integer;
     v_data   t_array;
     v_cont   integer;

     CURSOR cur_your_cursor
        IS
            SELECT DISTINCT LEADSEQ 
              FROM ASSIGNMENT 
             WHERE SEQID IN (SELECT ID FROM ASSIGNMENTS_DELETED);
        BEGIN
            v_cont := 0;
            FOR i in cur_your_cursor
            LOOP
                    v_cont := v_cont + 1;
                    v_data (v_cont) := i.LEADSEQ;
            END LOOP;
            For x in 1 .. v_data.count
            loop
                pipe row (TypeObject_LEADS_DELETED(v_data(x)));
            end loop;
            RETURN;
        END your_function;

Then, you can call this function anywhere, for example:

select * from table(your_function);

If you can't create Object Types (you have no grants, for example), as your temporary tables seems only an array of integers, you could use only the first part, avoiding returning anything or pipelining or creating types outside your procedure. In v_data variable you had all your desired ID's. You can use it, for example, something like this:

    For x in 1 .. v_data.count
        LOOP
          insert into ASSIGNMENTS_DELETED
             select SEQID FROM ASSIGNMENT 
             WHERE LEADSEQ IN (v_data(x)) 
             AND  SEQID NOT IN
                   (SELECT SEQID FROM ASSIGNMENT 
                    WHERE ROLE = 6 AND STATUS = 8 
                   AND CLOSINGTIME < closed);
       END LOOP;
