I have written a function that returns the pipelined pkg
Now When I do an INSERT to TABLE 1 FROM TABLE O and one of the TABLE O column value being fetched from the function that returns the pipelined pkg  as below


CREATE OR REPLACE FUNCTION FNC_AGG_GET_BUCKET
    (
      pi_template_desc VARCHAR2,
      pi_as_of_date DATE,
      pi_cashflow_date DATE
      )
    RETURN PKG_PIPELINED_TENOR.piped_buckets PIPELINED

------

INSERT INTO TABLE1 (
column1,
column2,
column3,
column4) VALUES 
SELECT 
 O.COLUM1,
 O.COLUMN2,
[b] (SELECT A.COLUMN1 FROM TABLE(FNC_AGG_GET_BUCKET('4G',V_AS_OF_DATE,O.MATURITY_DATE))A),[/b]
O.COLUMN4
FROM TABLE O

Open in new window


Is there any better way of doing this ?

First of all.. the insert statement is not valid.. you cannot have the values clause when you are using select statement..!!


I think you have just pasted the definition of the function..!!

is column3 data type the same from the output of pipelined function???

if its same then its ok??


well, i don't see anything wrong in the approach .?? you can go ahead and use this

do you have any errors as such?, if yes then let us know..!!

You may not need a pipelined function here. You are getting a single row out of the function, that may as well be achieved with a normal function.

And if the logic of the function is not complex, you may as well get rid of the function and
- Convert is as join or
- Write it as a scalar subquery

that will certainly perform better.
