Pipelined functions in BIP

http://forums.oracle.com/forums/thread.jspa?messageID=2820319�

Wanted to use the pl/sql package in datatemplate ?
Yes, we can use them in different ways, by using the oracle table function or Pipelined Table Functions.

Pl/sql package will return the collection variable , which you can cast it as table in the query..
sample

create type numset_t as table of number;
/

create function f1(x number) return numset_t pipelined is
begin
for i in 1..x loop
pipe row(i);
end loop;
return;
end;
/
select * from table(f1(3));

COLUMN_VALUE
1
2
3

In the datatemplate , you can just call the

select * from table(f1(3));

Or even the parameter can be passed to the function, in which your entire logic can be written, which will return the collection variable.

Datatemplate wil be more powerful , when used like this,
