Problem with nested loops in collections

Question

Hi All,
I am trying to insert data captured on a form(elements) into a database table thru a view.
I have a process for insert that looks like..
for x in (select * from htmldb_collections where collection_name = 'PARTY')
loop
for i in 1..50
insert into imds_part_num (mdb_nr,part_nr) values(:P5_MDB_NR,to_number(x.c00(i)));
end loop;
end loop;
the error is 'C00' must be declared.
I have no error when i tried to insert with process like this....
for x in (select * from htmldb_collections where collection_name = 'PARTY')
loop
insert into imds_part_num (mdb_nr,part_nr) values(:P5_MDB_NR,to_number(x.c001));
end loop;
i have 50 items on my form page . i added members into the collection like this,
htmldb_collection.add_member(p_collection_name => 'PARTY',
p_c001 => :P5_ENTWICKLUNGSNUMMER,
p_c002 => :P5_GEHAEUSE_PT,
p_c003 => :P5_GEHAEUSE,
p_c004 => :P5_PRESSTEIL,
p_c005 => :P5_MAEL ,
p_c006 => :P5_KGE_WNZ......, before the process mentioned above....
I see the collection as a VARRAY.
Cud somebody point me the mistake, or a workaround for this.
Thank you.

Chalamalasetty,
When you have -
x.c00(i)You're actually trying to access the Nth item in an array, for example if i=2 then you're trying to access the 2nd item in the c00 array.
However, your query which performs the select from htmldb_collections is not returning an array called c00, it does infact return distinct columns such as -
jes@DBTEST> desc htmldb_collections;
Name                                         Null?    Type
COLLECTION_NAME                              NOT NULL VARCHAR2(255)
SEQ_ID                                       NOT NULL NUMBER
C001                                                  VARCHAR2(4000)
C002                                                  VARCHAR2(4000)
C003                                                  VARCHAR2(4000)
C004                                                  VARCHAR2(4000)
C005                                                  VARCHAR2(4000)
C006                                                  VARCHAR2(4000)
....... extra lines deleted .......So you would need to specify the columns individually. If you wished to do this dynamically then you would need to make your insert statement a dynamic statement and build it up as a string.
If you can explain precisely what you're trying to achieve then it will be easier to suggest alternative ways of doing it.
