Hi all,
I need a select that will bulk collect some data in my nested table.
I have two tables from which I need to select all the accounts only once.(remove duplicates).
Tried to search on the forum...but no luck.
I have a table with one column:
create table a1(account_no number);
and a second table with 3 columns.
create table a2 (account_no number, name number, desc varchar2 (100));
I have a nested table like:
table of a2%rowtype;
Can I select from this two table in one select and put in my nested table just one row per account?
if a I have in a 2a row like :
1 'test' 'test2'
2 aaaa aa
and in a1 a row like:
1
I want to put in my nested table just (1, null,null and 2,aaaa, aa)) or (1,test,test2 and 2,aaaa, aa). it does no matter what row from those two I insert.
Second question:
If I use:
BANNER

what is the best solution to remove duplicates from a neste table like mine?
I thought that I can build another nested table and loop in my first nt and for each row I check in there was the same account in previous lines.
it will be like:
for i in 1....nt_first.count loop
for j in 1..i loop
--check if my line was in previous lines. if it was...do not move it in my second collection
end loop;
it is this best option in oracle 9i?
