Concatenate fields of record type

Question

Hi
Is there some way to concatenate fields of the record type ?, example
declare
TYPE customer_sales_rectype IS RECORD
      (campo1 char(3),
      campo2  char(3),
      campo3  char(3));
  TYPE ZZZ IS RECORD (kkk customer_sales_rectype);
      x customer_sales_rectype;
begin
  x.campo1:='000';
  x.campo2:='aaa';
  x.campo3:='BBB';
end;I have a table
ID_REPORT NUMBER                                  
ID_LINE     NUMBER                                  
DT_FILE  DATE           Y                        
DS_LINE     VARCHAR2(2048) Y        My quey have more than 50 columns and must to concatenate columns, example:
select column001 ,
       ';' PV1,
       COL2,
       COL3
       COL4,
     ';' PV2,....ETC
FROM MY TABLESI think moving result of query into variable of record type I would can insert into table in column DS_LINE doing some transformatcion.
Is there some way without to use COL1||PV1||COL2||COL3||COL4||PV2... etc
thank you in advance

It's easy enough to write a function to do this. Here is a "coffee time" implementation:
create or replace function multi_concat
    (p_args sys.dbms_debug_vc2coll)
    return clob
as
    rv clob;
begin
    dbms_lob.createtemporary(rv, TRUE);
    for i in p_args.first .. p_args.last
    loop
        dbms_lob.writeappend(rv, length(p_args(i)), p_args(i));
    end loop;
    return rv;
end multi_concat;
/And the proof of the coffee is in the dunking of the doughnut:
SQL> select multi_concat ( sys.dbms_debug_vc2coll ( ('Red Fish', 'Blue Fish', 1, 'Fish',2,'Fish'))
  2* from dual
MULTI_CONCAT(SYS.DBMS_DEBUG_VC2COLL('REDFISH','BLUEFISH',1,'FISH',2,'FISH'))
Red FishBlue Fish1Fish2Fish
SQL> I would add a TO_STRING member function to your type and use something like the above to implement it.
Alternatively, use the data dictionary to generate a string which joins all your type's attributes with the concatenation operator.
