Joins between DATA COLLECTIONS and TABLES

Question

I would like to know if is there any way to create one data collection with a query result, but I must join this data collection with an exist table, I cant use the GLOBAL TEMPORARY TABLE because I cant create a table in the module. I would like to do just what the SQL Server do with the @.

Answer 1

sql>create type tnumbercollection as table of number;
  2  /
Type created.
sql>declare
  2    c  tNumberCollection;
  3  begin 
  4    select employee_no bulk collect
  5      into c
  6      from mrt_user_master
  7     where rownum <= 5;  -- build collection of 5 employee numbers
  8 
  9    for r in (select um.last_name
10                from user_master um, table(cast(c as tNumberCollection)) t
11               where um.employee_no = t.column_value) loop  -- join the collection to the table
12 
13      dbms_output.put_line( r.last_name);          
14 
15    end loop; 
16  end;
