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,

Repeat Table Header in all pages in BIP

how to repeat the column titles on a table in all pages if the table extends over several pages What you need to is: 1. Select and Highlight the table header row 2. Right click and select table properties 3. On the Row tab properties , specify that the header row should be repeated on every page 4. Save the RTF 5. BIP looks at the properties of the word settings for the table and will repeat the header row on every page the table needs. This works so well in PDF output, but RTF output seeems to have some issue with this header repeat functionality We all can beleive, In future releases this bug won't be there ;)

Limit rows per page

Solution to have fixed number of rows in each page. This solution is not a perfect solution considering the line size increases due to text in each line. But this solution gives you how to fix no of rows per page. In the forum Heated discussion Users are arguing for having a placeholder in same fixed place on all pages, irrespective of no of lines , increased line size due to word-wrap. Here i am not going to discuss anything related to that. But a simple logic of , how to fix number of rows. Step 1: Loop through the records and display them Step 2: Have a condition for MOD of position(), then insert a page-break on the result of Zero Step 3. Blank row has to be filled, a condition has to be added, to find how many blank rows ROWLIMIT - (count of row mod ROWLIMIT) will gives us the rows to be filled. Step 4: use foreach_number function to simulate the iteration. Refer the images below
