Getting data into another collection from UNION of 2 collections

Question

Hi,
I have a requirement like this.
cursor c1 is
select a,b,c,d from abc
UNION
select e,f,g,h from def;
I am replacing cursor with collection variables.
Created collection variables for both the select statements as
select a,b,c,d BULK COLLECT INTO coll_abc from abc;
select e,f,g,h BULK COLLECT INTO coll_def from def;
Now, I want to get the UNION of both these collections into another collection variable.
Can I write
select * BULK COLLECT INTO coll_abc_def from coll_abc,coll_def;Thanks

Hi,
I ran into some problem here.
TYPE main_coll is RECORD (
     dte_ent_woc date,     
     sched_beg_dte_woc date,     
     inst_dte_woc date,     
     sub_acct_no_woc number,     
     wo_stat_woc varchar2(5),     
     wo_key_woc number);
TYPE main_coll_typ IS TABLE OF main_coll;
main_collection_union main_coll_typ;
-- Declaration Ends
BEGIN
   err_loc      := 10;
   file_name    := '14932_welcome_call_'               ||
                   TO_CHAR(TRUNC(SYSDATE), 'YYYYMMDD') ||
                   '.txt';
   file_handle  := UTL_FILE.fopen('/apps/custsrv/custsrv/data/output',
                                  file_name,
                                  'W');
   UTL_FILE.put_line(file_handle,
                     '"DV DATE"~"SCHEDULE DATE"~"INSTALL DATE"~"ACCOUNT
#"~"ADDRESS1"~"ADDRESS2"~"CITY"~"STATE"~"ZIP"~"ACTIVATION DATE"~"CURRENT BALANCE"~"DV STATUS"~"ACCOUNT
STATUS"~"RESTART DATE"~"IS DV LAST?"');
   err_loc      := 20;
SELECT  dte_ent_woc,     
     sched_beg_dte_woc,     
     inst_dte_woc,     
     sub_acct_no_woc,     
     wo_stat_woc,     
     wo_key_woc
BULK COLLECT INTO main_collection_union
FROM ((SELECT dte_ent_woc,
             sched_beg_dte_woc,inst_dte_woc,
             sub_acct_no_woc,
             wo_stat_woc,
             wo_key_woc
        FROM woc_base_comp
       WHERE
          wo_typ_woc = 'DV'
         AND MOD(INSTR(wo_rsn_woc, 'BF'), 2) != 0)
      UNION
      SELECT /* index(a DTE_ENT_WOO_I) */
              dte_ent_woo,
              sched_beg_dte_woo,inst_dte_woo,
              sub_acct_no_woo,
              wo_stat_woo,
              wo_key_woo
        FROM woo_base_open a
       WHERE
          wo_typ_woo = 'DV'
         AND MOD(INSTR(wo_rsn_woo, 'BF'), 2) != 0
         AND wo_stat_woo in ('X','O')
       );When I compiled, I got these errors...
Error(146,10): PL/SQL: Statement ignored
Error(146,51): PLS-00302: component 'SUB_ACCT_NO_WOC' must be declared
Error(155,10): PL/SQL: SQL Statement ignored
Error(159,35): PL/SQL: ORA-00904: "MAIN_COLLECTION_UNION"."DTE_ENT_WOC": invalid identifier
.I understand that the declared collection is not being recognized.
But, I am not getting where to declare and where to define the collection.
Any help regarding this would be appreciated.
Thanks
Rajiv
